The Difference Between LED Projector Light and LED Flood Light

The Difference Between LED Projector Light and LED Flood LightLED Projector Light (LED Downlight) call spotlight again, cast shoot light, shoot light to wait a moment, basically use to do building adornment illume to use, and commercial space illuminates with, the component of adornment sex is heavier, its appearance has circle also have square, because must want to consider commonly the reason that come loose, so its appearance and traditional cast light still have a few distinction.LED projection light features:LED projection light is controlled by a built-in microchip, which can be used without a controller in small engineering applications. It can achieve dynamic effects such as gradual change, jump change, color flicker, random flicker, gradual change and alternation, etc. It can also achieve chase, scan and other effects through the control of DMX.LED Flood Light is a point light source that can be irradiated uniformly in all directions, and its irradiation range can be arbitrarily adjusted, which is shown as a regular octahedron in the scene. Omni is the most widely used light source in rendering. Standard omni is used to illuminate the whole scene. Multiple omni lights can be used in the scene to produce better results.Features of led flood lights:LED omni lights, which shine evenly in all directions from a given point, are the best analogy to light bulbs and candles. Floodlights can be placed anywhere in the scene

If I flick the light switch on and off will it damage the light?

That statement originated (to my knowledge) in the damage that can be caused to incandescent lights (those that produce light as a result of [super] heating some element in the light).Fluorescent lights can also be damaged by repeated on/off switching of the "switch," still due to a startup-effect, but differently than incandescents

If a light year takes light to travel a year...?

A light-year is a measure of distance NOT time. As is a light-month or a light-day. A light-year or lightyear (symbol: ly) is a unit of measurement of length, specifically the distance light travels in a vacuum in one year. While there is no authoritative decision on which year is used, the IAU recommends the julian year. Other units of measurement of distance used in astronomy are a parsec and an Astronomical Unit. Here are some conversion factors: 9.46110^15 metres 9.46110^12 kms 9.46110^18 mm 94.60710^24 63.24110^3 AU 3.26 parsecs US customary / Imperial units 372.4710^15 in 31.03910^15 ft 10.34610^15 yd 5.87910^12 miles So if a light-year is just under 6 trillion miles, a light-month must be just under half a trillion miles and a light day about 16.3 billion miles It is about 40 light minutes from the Sun to Jupiter, 5.5 light hours to Pluto, 4.2 light years to the nearest star (Proxima Centauri) 10.5 light years to the nearest star with a planet (Epsilon Eridani) and 20.4 light years to the nearest star with an inhabitable planet (Gliese 581c). Hope that helps put it all in perspective.

What happens to light after it enters an eye

There is some heating that takes place, but the amount is pretty trivial, because there just is not that much light reaching the back of your eye. A back-of-the-envelope sort of estimate would be to say that the light of the Sun reaching the Earth's surface amounts to about a kilowatt of radiation per square meter. Your pupils have a radius of maybe a millimeter, probably much less in bright sunlight. So, if you are staring directly at the Sun (which, hopefully, you are not really doing), you are getting at most a few milliwatts delivered to the back of your eye. That's not going to tax the temperature regulation systems in your body, given that a living human generates about the same heat as a hundred-watt light bulb.If you dramatically increase the amount of light delivered to your eye, say by accidentally catching a high-power pulsed laser in the eye, you can overwhelm the body's ability to carry away the heat, and do real damage. The pulsed-laser lab next to the office where I did my undergrad thesis research had a sign on the door explaining in gruesome detail what would happen if you were to catch a full YAG laser pulse in the eye, which involved the boiling retina basically blasting your eyeball out of your skull. Which is why you wear safety glasses in those labs, and knock before entering any optics lab

Assume Two Objects Are Travelling Less Than Half of the Speed of Light to Opposite Directions and Ob
Perhaps you can answer it yourself by looking at Velocity-addition formula - WikipediaThere are two different addition formulas: "Galilean relativity" and "Special relativity".You seem to be assuming Gailean relativity - where velocities simply add, and also that the speed of light is relative to the emitter. Both of those assumptions are false, you need to read the "Special relativity" section and accept that both objects will measure an unchanged velocity of light. Each object will see the other object red-shifted, not vanishing— — — — — —Is there a new discovery that the speed of darkness is faster then the speed of light?light and darkness form a dichotomy pair... one is dynamic, the other static. Hence the characteristics of a static are opposite to those of a dynamic. Furthermore if darkness showed any indication of being dymanic, scientists would have reocnised this long ago since it is such a fundamental issue to the structure and function of the universe.— — — — — —Did Einstein consider the speed of light as a universal constant?Yes.He believed that speed of light is constant forever...Even though u make a race with light to achieve light speed and make to going constant of u and light,the light would definetely have 3,00,000km/s with compared to u also even though u travelling with nearly equal to speed of light..Because the light have that behavior....note: achieving of light speed is not make so hard to believe in some thousand years later..But changing the speed of light is impossible with compared to any reference....— — — — — —What speed does current travel through wires?The electrons in a wire move very slowly. centimeters per minute. But the electric current that gets passed down the wire moves at the speed of light.— — — — — —Is the speed of light the fastes form of travel?The speed of light is a measure of.um.SPEED. Not a vehicle— — — — — —How many times faster is the speed of sound that the speed of light?I think this question deserves a direct answer.The speed of sound in air varies with the air density and humidity, but a typical value is 343 meters per second. If you're not familiar with the metric system, a meters is about 39 inches, or a little more than one yard. The speed of light is 300 million meters per second. A more precise value is 299.8 million meters per second.If we divide, we get roughly 1.14 x 10^-6. So the speed of light is about 1/0.00000114 ≈ 877,193 times 'faster" than sound. Another way to say this is that the speed of sound is about one millionth the speed of light. Or that light is about a million times faster than sound.And yes, most people would just say sound was 'slower" than light. But you can multiple by a tiny fraction instead, if you like. Whatever math gives the right answer is fine. Some ways of doing the math seem more clumsy than others, but that's just a subjective judgment— — — — — —Why is the speed of light the speed it is?I have written about this.The speed of light is what it is, because the characteristics of the vacuum.The vacuum permittivity, "εo", is a physical constant which represents the capability of a vacuum to permit electric fields. It is also connected to the energy stored within an electric field and capacitance. The vacuum permeability, "μo", is derived from production of a magnetic field by an electric current in a vacuum.But this is a little hard to understand. Just understand that in any medium, electromagnetism behaves is a way that depends on the characteristics of the medium. In a vacuum, some characteristics (which determine the speed of light and all electromagnetic phenomena) have some residual influence.— — — — — —TrackPad Speed and Mouse Speed - Resets to slow every timeI had this problem but I had smoothmouse installed.

If not, is it due to the Higgs field?No and no. It is due to the limitations on geometry and causality.But see discussion: Does the speed of light vary in noninertial frames?I am concentrating on the misunderstandings evident in the question.The speed of light in GR is not related to the Higgs … GR does not know about Higgs, as Higgs belongs to a completely different theory. Similarly, there is no gravitational force in general relativity.Also see:Spacetime Geometry Inside a Black Hole

Typical VW feature. I always see taillight issues with VW and VW related cars (Audi, Porsche, Bugatti, Lambo, etc...)1. How to find a short in my signal lights?Get youself a multi task voltmeter and a bunch of mini-fuses from your auto supply store. Mini-fuses are generally for motorcycles they look like auto but half the size and double the cost. 10 amps is Red and likely what you will need. Get a dozen or so to do test. Voltmeter costs about 10-15 bucks. Pop seat and or side panels to locate the main wire harness a thick bundle of wires wrapped in black protective weather-proofing that is likely beneath the seat near the battery. This harness usually has a seperated split of a smaller harness of 4-8 wires. These coloured wires have seperatable connections that control electricity to turn signals, brake and tail light, hot wired licence plate, and auxillary after market accesories. These are male / female connections and are housed in a wet proof sheathing. They have all colours. Consult your manual for the wire schematics and find the corresponding colours to circuit. The 'male' is likely the power source so with your voltmeter and the bike key turned on (or engine running) take a fresh mini-fuse insert into blown fuse slot. Now try different combinations with turn signals, brake levers pulled, use the horn, etc until you blow the fuse on purpose. you are narrowing the possible circumstances to find which combo or single electrical need causes the circuit to be shorted. Keep in mind the wire schematics will take all of the guess work out of the function of a wire. The wire can have 2 uses so study the wire plan. These 'hot' circuits mean they do not get switched off while the bike is running. The licence plate circuit is one example. Alternating circuits (left light/right light/brake light) will have one different wire colour to switch on its need and the other attached to a hot circuit. Your volt meter again is usefull to determine live circuits as long as you measure on the power feed side of the main wire harness. It takes a bit of detective work but once you get it you will have the benefits of knowing the causes and fixes if you break down on the road. When that happens you will only need extra min-fuses and tape to fix those problems.2. Why are my signal lights flashing as if i hit the emergency light button by themselves with no key?you probably put in a wrong fuse3. Im my 1992 lexus, all Signal lights work, except for the front passenger side.....?Forget the wiring, if a new bulb did not fix the problem, possibly the bulb socket is corroded or rusty, check that4. Can i have blue led front signal lights or are they illegal?Tough beans, amber is the colour required by FEDERAL law5. my signal lights don't work in my 81 cutlass?Use a 12 volt test light to see if there's power to the bulb's socket. If you have power there, then you have a bad ground. When you say 'signal lights' I assume you mean the turn signals. Have you checked the flasher module? (that little round can that makes the ticking noise when the light blinks on and off) It could be bad6. need help on troubleshooting my right turn signal lights!?Check out the front turn light.

Testimonials 1.Cataracts Disappear: A lady with cataracts had been blind for a number of years, and yet in nine days she had her full sight back. This astounded Dr. Christopher, for it to have happened so fast. Other people go on the program for as long as three years, and though they then can see better than before, they have not been completely healed. Others clear in a matter of months--it varies with the individual. 2.Dry Eyes and Cataracts: I have had bad eye trouble for two or three years. The beginning of cataracts on both eyes, I had the jel break in both eyes--at that time my eyes were so terribly dry that I would have to lift the eyelids off my eyes in the morning with my fingers. My vision was getting real bad. I have been taking exercises for my eyes, using the eye wash and taking the Eye Wash Formula. My eyes are much, much improved. I am positive that the cataracts will be completely dissolved. Thank God for you and the wonderful work you are doing. 3.Cataracts, Glaucoma and Bad Vision: I was diagnosed as having a fast growing cataract in my right eye and a build-up of pressure in both eyes causing glaucoma. I then found in Newsletter #19 all about Herbal Eyewash [Herbal Eyebright] and capsules, which I ordered and received on November 4. I immediately started using both three times a day--with marvelous results. Within three days I could see through my new glasses, bi-focals. I had not been able to since I got the new glasses which had stronger vision for distance and weaker bi-focals. So I had to change to my old glasses for my bookkeeping work and the new ones for driving. Suddenly I realized I forgot to change them when I sat down at my desk at my office (because I was seeing figures perfectly, I had forgotten I had them on). Then within two weeks I suddenly realized I could see much farther with the bad eye with the cataract, when I could not see with it at all before. All along small pieces of mucus is coming out of my eyes many times daily. Before using eyewash, I could not stand driving after dark as the car headlights, tail lights, signal lights and street lights all had huge halos around them of flashing red, yellow and green, very scary. So I had to be very careful not to leave my office so I would get home after dark. Now the halos have disappeared and I see only a tail on each light which I think looks like only a small part of a halo and I take that to mean my eyes are improving. I am very happy with continuing improvement and have full confidence that my cataract and glaucoma will be cured. I have started two friends using it too, and they both tell me they are having good improvements too. Neither have cataracts or glaucoma, but they do have weak eyes and wear glasses. 4.Vision Improves: I started the Eyebright formula treatment... TWO WEEKS AGO. My vision has improved immensely, needless to say my first few days of treatment were rather hectic, but as I read the doctor's answers to questions in the Healthview letters, I was encouraged to go on. I bought the herbal eye-wash powder so it was necessary for me to strain it as I made it each morning. In preparation I had bought a box of filter drip coffee filters rather than using the gauze. When I poured the tea through the filter, it plugged up almost immediately. So the next morning, I put a teaspoon of the powdered tea in the filter, tied it shut with a twistum, thus making a tea bag. Bring the cup of distilled water to a boil with the tea bag in it. Let it stand until it cools. Works beautiful. No fuss no muss. Someone else has probably already thought of this method. I will write you more as it progresses. Eyebright Formula has helped me and a few friends of mine. I would give it a try. Best of health to you. Cheers

The membrane is not ciliated. Cryptomonas cells are fairly large; they average about 40 micrometers in size and often take the shape of an oval or ovoid. There are two flagella present, yet the two flagella are not equally sized. One is shorter and curled and the other one is longer and straight. The two flagella are fixed to the cell by four unique microtubular roots. In addition, the flagella are lined with small hairs that allow for better movement. There are also contractile vacuoles that control the flow of water in and out. Two boat-shaped plastids are observed in the cells. In a secondary endosymbiosis event, the phagotrophic ancestor of the Cryptomonas presumably captured a red alga and reduced it to a complex plastid with four envelope membranes. The phycobilisomes of the former red algae were reduced until only phycoerythrin remained. Phycoerythrobilin, a type of red phycobilin pigment, is a chromophore discovered in cyanobacteria, chloroplasts of red algae and some Cryptomonads. Phycoerythrobilin is present in the phycobiliprotein phycoerythrin, the terminal acceptor of energy during the process of photosynthesis. The phycoerythrin was translocated into the thylakoid lumen with its chromophore composition altered; subsequently, phycobiliproteins with at least seven different absorption spectra evolved. Cryptomonas is distinguished by the purple phycoerythrin 566 as an accessory pigment, which gives the organisms a brownish color in appearance.— — — — — —can you see a cell using a 900x microscope?Depends what kind.

The cancer may derive from the microscopic Merkel cell nervous organ in the skin and viscera which is responsible for touch and pressure sensation. Based on its origin, the cancer cell type is called a neuroectodermal tumor. Although rare compared with other skin cancers, the incidence of Merkel cell carcinoma in the USA tripled between 1986 and 2001, to around 1400 cases per year. Merkel cell carcinoma is mainly seen in older individuals. It is known to occur at increased frequency in people with immunodeficiency, including transplant recipients and people with AIDS, and this association suggests the possibility that a virus or other infectious agent might be involved in causing the cancer. Kaposi's sarcoma and Burkitt's lymphoma are examples of tumors known to have a viral etiology that occur at increased frequency in immunosuppressed people. Other factors associated with the development of this cancer include exposure to ultraviolet light. Eight of 10 Merkel cell carcinoma tumors initially tested were found to be infected with MCV. In these tumors, the virus has integrated into the cancer cell genome and can no longer freely replicate. Recent studies from other laboratories have reproduced these findings: in one study 30 of 39 (77%) of Merkel cell tumors were MCV positive; in another study, 45 of 53 (85%) Merkel cell tumors were positive. Sequencing of the virus from Merkel cell cancers reveals that it generally has tumor-specific mutations that truncate the MCV T antigen. These mutations (which are not found in native virus obtained from nontumor sites) eliminate the T antigen helicase, preventing the integrated virus from replicating independently from the host cancer cell. The tumor is a "dead-end host" for MCV. Normally, the virus exists as circular episome (or plasmid) within the cell and its DNA is packaged into viral capsids and transmitted to other cells. In tumors, the viral DNA has broken and become integrated into human DNA within the tumor, so that the virus is no longer transmissible. The integrated virus cannot be excised from the host cell and it must replicate as the host cell is replicated. Examination of infected tumors reveals that the majority have a clear monoclonal pattern, indicating that the virus integrated into a single cell before it began its cancerous expansion. For this reason, there is very strong evidence that MCV causes some, but not all, Merkel cell carcinomas. MCV can also be found in healthy tissues from people without Merkel cell carcinoma. A complete MCV genome (MCV-HF) was designed from multiple tumor-type MCV genomes and examined with successful replication capability in vitro. The identical sequences were found in human normal skins. While the precise prevalence of infection is unknown in humans, it is likely that most infections do not cause cancers.
How You Can Make Money on Solar Street Light with Lithium Ion Battery Products
How You Can Make Money on Solar Street Light with Lithium Ion Battery Products
Since lithium-ion batteries are the preferred battery type for outdoor lighting, we strongly recommend that you choose this type of battery. Lithium ion and lithium phosphate batteries are the best choice for solar lighting systems, especially those used in the same lighting system, such as solar street lights. Lead-acid batteries are commonly used to illuminate ordinary household and emergency lights. There are two commonly used batteries for solar street lights: deep-discharge gel batteries and lead-acid batteries.If you are looking for high quality and long lasting solar garden lights, you should look for those that have lithium ion batteries. Generally, you shouldn't worry too much about lithium solar panels right now. Currently, most universal solar LED street lights on the market use 18650 type lithium batteries and in some cases 26650 type.If you think your solar lights won't last much longer outdoors, and you don't want to spend more on lithium-ion batteries, then opt for nickel-based solar panels. This means it may be more practical to purchase a more expensive lithium battery powered solar street light than a solar nickel cadmium light fixture. The battery size requirement for sunlight application is inconvenient.Solar landscape lights must provide high-quality light, otherwise their service life will be affected. Recently, solar lights have become more and more popular when used in streets, stadiums, homes, and other outdoor places that require night lighting. You can also use these convenient lights by purchasing suitable options such as SZYOUMY solar street lights.We love the fact that this sunlight doesn't emit as much heat as regular LED bulbs. While there are solar panel adjustment options, this luminaire has a highly efficient auto-tracking system that blocks the solar panel in the sun all day long. Light depends on the heat energy emitted by the sun and accumulates most of it during the day.Solar panels charge a battery that powers a fluorescent or LED lamp at night. Photovoltaic panels have a rechargeable battery that supplies power to a fluorescent lamp or LED during the night. Batteries allow the light to work in bright mode for 10-12 hours and then go to dim mode for over 60 hours; hence, providing sufficient lighting for several days even when there is no sun. When the battery is fully charged, the light can work for 12 hours, practically overnight.The battery provides over 24 hours of continuous illumination. Keep in mind, however, that battery life and lighting are dependent on the intensity of sunlight. On cloudy days, the lighting time will be shortened because the battery will not be fully charged.Even in cloudy days, solar panels can provide 3V voltage and charge the battery. Battery life is 4-5 years, maintenance-free. It can be equipped with a 3.6V battery, which can be used for some solar garden lights. It can use 12V battery directly or run through solar and battery charge controller. Equipped with 18000mAh battery, charging for 6-8 hours, lighting for 10-12 hours.Solar garden lights using nickel-based rechargeable batteries can last no more than 2-3 years. Battery life is very important to the life of a flashlight, and battery capacity affects the number of days a flashlight can run on its own.A battery pack can give you additional control over your home's power supply, allowing you to maintain essential devices (such as medical equipment, refrigeration equipment, air conditioning, electric heating, lighting, and well pumps) during power outages. In favorable solar conditions with limited home electricity use, combining a solar panel with a rechargeable storage system can help your devices stay powered up for days. Installing 30-watt solar-powered LED street lights can provide the same light output, so installing lithium solar-powered street lights can save at least 80% on your electricity bill.From our analysis of these solar roads, we are pleased to note that they emit very bright light, aided by 28 super-bright LEDs. They can glow on subsequent nights, even if solar energy is unavailable for several days. Besides powering homes and offices with photovoltaic modules, solar energy is also effective as an outdoor lighting solution. This is in the form of taxpayer-paid city lights that illuminate streets and other public places.Batteries store the electricity generated by the solar panel during the day and provide power to the unit at night. Batteries can provide the necessary backup power for your essential devices and appliances, such as medical equipment, refrigeration equipment, air conditioning, electric heating, lighting, and borehole pumps. Modern designs use wireless technology and fuzzy control theory to manage batteries.Ultimately, they can illuminate the entire road, area lights that are too bright, or the eyes of drivers or pedestrians, causing feelings of insecurity and discomfort. With these ENVIRONMENTAL LED solar floodlights, you can make the experience more realistic by making sure your complex has adequate nighttime lighting. The outdoor luminaire consists of a 40-LED 6500K lightbar, a stainless steel sensor and an aluminum screw base. The product is also equipped with a highly efficient LED light which helps to provide continuous illumination of the road even on days when sunlight reception is poor.As now, the efficiency of solar panels is higher, the capacity and cycle time of lithium-ion batteries are longer, the rechargeable solar street light controller, the brightness and power consumption of the LED lights make solar LED street lights more economical in terms of overall cost and production. A real ecological product. Modern solar lighting systems use lithium-ion batteries, which are much better than previous models. New energy subsidies have basically expired. Lithium batteries and battery panels are so cheap today-not counting light poles, this is the cost of laying 20 meters of cables, and each light pole requires at least 50 meters of cables. Smart control is the same. Most solar street lights are installed in backward areas. I don’t think that mountain village workers drive dozens of kilometers on mountain roads every day to adjust the light control time with their mobile phones. This is more like a pseudo demand. Save money and effort-either do not understand the technology, or sell the controller at a high price.The 3.2V system is a bit simpler than the 12V system, but this is not the point. Therefore, the simple design does not require cross protection. 3.2V lithium iron phosphate street lamp solar panels have an unprecedented opportunity. After 6 years of testing, the failure rate is much lower than that of municipal street lamps. In order to solve this problem, some solar lamp manufacturers will make a protective cover for your external solar panels or bury them in the ground.
Dark Spots on Face
Dark Spots on Face
Every woman longs for a clear, translucent, blemish-free complexion. However not many of us are blessed with an even complexion, and blemishes in the form of dark spots or brown spots are quite common. But it is possible to get rid of these unsightly dark spots with the right beauty products and procedures. To know more about the causes and remedies for dark spots read on...Dark spots are a problem that most women encounter at some point in their lives. These dark spots or brown spots generally appear in and around the cheeks, arms and hands. People with fair or wheatish complexion are more prone to brown spots. Sun exposure is one of the main reason for appearance of dark spots, and the problem with brown spots is that they can make you look older than your age. Hiding behind a layer of foundation or concealer is not the answer and you need to know the causes for the appearance of , before you can consider some of the remedies for fading them. There are various reasons why dark spots appear on the face. The most common cause is extensive sun exposure. Our skin contains melanin, and in order to protect our skin from the harmful ultraviolet rays of the sun, melanin absorbs the rays resulting in tanning of skin. Excessive exposure to sun for a long period of time causes a concentration of melanin, which results in the appearance of dark spots, sun spots or age spots on the skin. Dark spots on the face might also be due to fluctuating hormones during pregnancy or menopause. Stress, aging, acne, genetics, use of birth control pills and liver diseases might also cause pigmentation in the form of brown spots. There are a couple of ways in which you can fade brown spots or dark spots from your skin.One of the best way to counteract this problem is to prevent the occurrence of dark spots by minimizing sun exposure. Apply a broad-spectrum sunscreen with a minimum SPF of 30, even when you are indoors. A broad spectrum sunscreen shields the skin against both UVB and UVA rays. For added protection apply a sunscreen over an oil free lotion that contains green tea or vitamin C. Products containing active ingredients like alpha hydroxy acids, beta hydroxy acids, salicylic acid, vitamin C and Retin A helps in fading dark spots by sloughing off dead skin cells. To eliminate the toughest of dark spots, use a skin lightening cream that contains hydroquinone or kojic acid. However prolonged use of these ingredients can cause discoloration of the skin, so always consult a reputed dermatologist before applying them.Intense pulsed light therapy (IPL) can be highly effective in eliminating dark spots from hands and face. The laser light penetrates deep into the skin and it is absorbed by the area with dark spots, which darkens over the next couple of days. The skin looks dark and blotchy for about a week, then the spots slough off revealing clear, fresh skin. There may be a slight amount of redness and stinging, but it disappears within a week. People who want to reduce the appearance of fine lines and wrinkles, can also greatly benefit from intense pulsed light therapy.A non-surgical, safe and highly efficient method for removing dark spots from face is microdermabrasion. In this process the skin is very gently abraded with microscopic crystal particles, generally aluminum oxide crystals. It is a painless procedure, and you can resume your daily activities immediately. For safe and efficient treatment of brown spots you can also consider chemical peels. This is very effective in removing caused due to acne. An acid of mild concentration, usually glycolic acid is applied on the skin to "peel" off the outer layer of skin. A neutralizer is then applied over the skin revealing fine-textured healthy skin free of pigmentation. Six to eight sittings are required to get the best results.Here are some home remedies for removing dark spots.The best way to prevent the appearance of dark spots is regular application of a good quality sunscreen that contains SPF of above 30. Also avoid prolonged exposure to sun. Over the counter bleaching agents are your best bet if you are looking for an easy and inexpensive option to fade away dark spots. For quicker results, you can always opt for chemical peels and intense pulsed light therapy.

Wedding rings are not made from steel2. are whitetail deer spooked by flashlight light?a deer, will usually stop & look at a sudden bright light before moving off, which allows poachers, to be so effective at night. they will spook, if there is much movement of the light3. What flashlight is most popular with police these days?The one that puts the biggest dent in some combative jerk's head4. Can you point a flashlight at a cop?These days you could be shot before you even flicked the light on. Not smart on either yours or the cop's part5. can i use a l.e.d flashlight to do a photoelectric experiment?generally speaking red, blue, and green should give a white light when combined but this must depend upon the precise wavelengths of the respective colours. The light should be more or less white however. In this event there is no reason why you sghould not be able to do such an experiment. .. light is light after all and any colour light should render the experiment a success !! The only differences in the colours is that the shorter wavelengths (toward the blue and away from the red ) generally have a higher energy content given that the intensities are equal in all cases6. how big flashlight to see if eggs are fertilized?the term is called candling ( in the old day's they used candles ) so that should answer you are question7. can we use nikon remote control for any brand of flashlight?One of the most important things I have learned when it comes to using a flash is getting it off the camera. There is a good reason for that: it allows for more control over where I place the light. A very important tool for this is a wireless flash trigger. I tested out the Hahnel Combi TF Remote Control & Flash Trigger for Nikon DSLRs and, for the most part, I like it. It is a question of value really. If you can manage without a typical name brand like PocketWizard, you will find this interesting.As a remote control, the Combi TF allows wireless control of the camera's shutter release, auto focus, continuous shooting, bulb mode, and 4-second timer delay trigger.8. I have a Mag Lite 5 -D flashlight the batteries have leaked and I cannot get them out, WD-40 did not help?take off top and bottom of mag lite,take a screwdriver and hammer and knock the batterys out9. Where would I go to find an LED Flashlight?Target, Sam's Club, Sports Authority, Sears, JC Penny, Best Buy, Kmart, Walmart, Sharper Image10. Will using the iphone camera flash as a flashlight for long periods harm it in any way?I would say no for two reasons,The flash on an iPhone is an LED which unlike old camera flashes does not mind running for extended periods of time.Flashlight use is not limited by iOS. If the letting the flash run for a while would break the phone apple would not allow you to do so or at the very least set a timer to turn it off after so long.The only problem T could see is the bulb will eventually burn out, but considering you do not seem to need the camera anyway that probably is not an issue for you.11. Red Filtered Flashlight (similar to stargazing flashlights).?You need a red light for one main reason. First it help you keep you night vision because it takes anywhere from 30 min to 1 hour for your night vision to take full effect. A flashlight is good but you have to hold it. My guess is that you will be on a hike to get there? Get a headlamp. You can go to REI or Gi Joes but your going to pay a high price for a flashlight. The tissue paper is a good idea but it will rip. Instead of tissue paper you would be better to use a red ballon and a rubber band or tape. If you want it cheap, and I know cheap go to Walmart, Target, some store. Go to the sporting goods section and they will have headlamps. Read on the box. Get a LED one because the thing will break before the bulb will. The AAA are the best ones because they are small and put out the most powerful light. The headlamps will most likely have a white light and a red light so the light is good for both and you do not have to worry about a ballon, tissue ripping or a filter that falls off. I have had a lot of flash lights and these are the best. Hands free the way to be.
Visible Light Beams
Visible Light Beams
Visible light beamsFrom the side, a beam of light is only visible if part of the light is scattered by objects: tiny particles like dust, water droplets (mist, fog, rain), hail, snow, or smoke, or larger objects such as birds. If there are many objects in the light path, then it appears as a continuous beam, but if there are only a few objects, then the light is visible as a few individual bright points. In any case, this scattering of light from a beam, and the resultant visibility of a light beam from the side, is known as the Tyndall effect. Visibility from the side as side effectFlashlight (UK 'Torch'), beam directed by hand Headlight, forward beam; the lamp is mounted in a vehicle, or on the forehead of a person, e.g. built into a helmet Lighthouse, beam sweeping around horizontally Searchlight, beam directed at somethingVisibility from the side as purposeFor the purpose of visibility of light beams from the side, sometimes a haze machine or fog machine is used. The difference between the two is that the fog itself is also a visual effect. Laser lighting display- Laser beams are often used for visual effects, often in combination with music. Searchlights are often used in advertising, for instance by automobile dealers; the beam of light is visible over a large area, and (at least in theory) interested persons can find the dealer or store by following the beam to its source. This also used to be done for movie premieres; the waving searchlight beams are still to be seen as a design element in the logo of the 20th Century Fox movie studio.— — — — — —How would one construct a realistic “infrared vision” effect?What you normally see from the world is the visual part of light which is reflected by objects. A green object reflects only green light, a red object only red light and a blue object only blue light. Infra-red can be considered a fourth color which your eyes can not perceive. An infra-red camera makes infra-red light visible to you by perceiving it with a sensor and converting the infra-red image into wavelengths you can see.Just like some materials are more or less bright in red, green or blue, they are also differently bright in IR. The IR brightness can but does not necessarily has to correspond to how bright it is in visible light. Here is a scene in visible and in IR. Note how the leafs of the trees are much brighter in IR than the trunks, but the IR brightness of the different parts of the facade of the building is similar in visible and IR light.What you could do is create two versions of all of your textures: an RGB texture for visible light and an alternative monochrome texture for infra-red. In normal mode you use the RGB texture and in IR mode you use the IR texture. You might also consider to use different light-sources in IR mode. The sun produces as much IR light as visible light. But artificial light-sources (like halogene lamps or light-emitting diodes) produce few or almost no IR light, so they do not illuminate anything in infra-red. On the other hand there are light-sources which are much stronger in IR (like open fire) or only visible in IR (hot objects which are not hot enough to glow red. Or artificial IR light sources. Did you know that when you wear IR goggles, you can use a TV remote as a flashlight?). Different light-conditions in normal and IR light could be an interesting gameplay element.— — — — — —What does it take to be a Psychophysicist?See, colors are made up from different wavelengths of light, which is an electromagnetic wave. The wavelengths of visible light vary from about 400-700 nanometers. By varying the wavelength, you can change the observed color. There can be an infinite number of different wavelength in this range itself, as you can always have a very tiny decimal difference and still obtain another different wavelength: hence, a new color. Thus, there can be an infinite number of colors, though there are just three primary colors of light: Red, Green, Blue AND three primary colors for pigments: Cyan, Magenta, Yellow
What the Most Fun Thing You Can Do with the Lights Off?
What the Most Fun Thing You Can Do with the Lights Off?
Sex obviously!1. Your experience with the northern lights ?( 10 points!)?The gloomy days make human beings unhappy and without the solar, they are no longer uncovered to nutrition D it somewhat is why they are happier while it somewhat is heat out. additionally the quantity of photograph voltaic is constrained while in comparison with summer months, which makes human beings unhappy. And it somewhat is chilly and the chilly gets tiring after awhile.2. Do you like to do it with the lights on or off?I can not sleep if I have the lights on3. Ideas for my momsMaybe you could do a black and white winter scene (come on, what color does not go with black or white?) or a Christmas tree with a bunch of red/orange/blue lights on it. If you want to do modern, maybe you could do a cityscape in winter with a bit of snow and lights all around. I think that would be the most interesting but whatever you do, I am sure you will mom will love it! Hope this helps and happy holidays!.4. Flourecent light blinking after off?It's perfectly normal. Modern compact fluorescent lamps have a miniature DC power supply built into the base. A small amount of leakage current from the switch can charge up the power supply enough to provide a brief flash. Switcheds with built in lights that allow you find them in the dark are especially likely to cause the effect. Bulb manufacturers could eliminate the problem by adding a 2 cent resistor to the circuit but they would also reduce the overall efficiency slightly by doing so. Don5. Do you have a tip for hangingHow to hang outdoor Christmas lights is a big ordeal for a lot of people. Christmas is supposed to be a time of joy and laughter, but the whole process of putting up outdoor Christmas lights kills a lot of the fun. You should have some basic idea about how to put hang outdoor Christmas lights, so you can enjoy this as much as other yuletide activities. Hanging outdoor Christmas lights is not necessarily a difficult task. Take a look at our tips to simplify the job and make it a fun filled activity. Tip # 1 Plan early. Before Christmas is knocking on the door, you should know what exactly you want to do with your outdoor Christmas lights. If it snows and gets really cold where you live, start thinking about it right from the end of August, when the weather is still comfortable. A good idea is to hang icicle lights around the top of your house. For this, you have to screw in hooks under the roof. If you do that, you can put up the lights in a few minutes and there's no way you can make a mess of things. This is also applicable if you want lights around your porch or deck. Tip # 2 You would do well to put up the lights as early as October or November when it's not that cold. When the holiday season is around the corner, you can fit in a timer and turn them on. Tip # 3 You can teach your kids how to hang outdoor Christmas lights. They can do all the untangling while you do the actual job of putting the lights up. If the hooks are in place, putting up the outdoor Christmas lights is a piece of cake. Put the wires over the hook and they will stay in position; there will be no risk of damaging the lights. Tip # 4 From time to time, you will need to change the hooks (they are prone to rusting). But you surely do not have to do that every year. Let the hooks be after the holiday season too. You can use them again the year coming. Tip # 5 Measurements are important. You need to have at least a rough idea about the measurements of your home so you have enough lights to decorate the space. Tip #6 Make sure to test your lights before hanging them. Tip # 7 Get all the tools you need. These include a tape measure, pliers, a hammer and a ladder to complete the job. Tip # 8 Your ladder needs to be planted on flat ground. It is better and safer to have someone hold it when you are up on it. Tip # 9 Hang the lights along eaves. Take your time and be careful not to damage your home walls. If you want lights attached to your gutter, use plastic clips. These will stick with the gutter and hold the lights and extension cord.

How Do You Light a Wood Burning Fire Place?
Nothing. Just put like a gallon of petrol on to make sure it wo not die - fire-starters are a pure waste of money. With petrol you will clear the chimney at the same time. Jokes1. Why do flies land on the ceiling of my patio when we light a wood BBQ?They are doing the same thing as your neighbor does, but your neighbor does not land on the ceiling...he hangs on your fence...both hoping for an invite2. O.K. listen up, melt some candles and dip paper towels in the melted wax and role or wad them up then you only have to light one in your fireplace and add small pieces of wood then when the wood ignites add larger chunks until your fire is satisfactory. The old paper towel and candle wax trick is a excellent way to start campfires too3. Staining a light wood to a cherry finish...?You can clean off the finish and use a cherry varnish stain to paint it. I prefer stripping the old varnish off and sanding it smooth and using a water based cherry stain to get the color I want, then either put a clear polyurethane finish or just do an oil finish with many coats. Depends on how much you treasure the piece and the effort you want to apply.4. dark wood and light wood together? bad idea needs fixed please help.?To me, it would be the focal point of the room! Make it look pretty and then add a couple dark things around the room, like a vase or lamp, you know accessories to sort of tie the room together!5. What color should I paint the walls in a bedroom with light wood floor, a earthy-brown bed and lots of light?I can give you thrree thoughts but i havent seen the room cause ceiling height and base board color plays a part too. Thought one which is easy painting, a very deep red which will absorb the light and enhance your comfort set. thought number two, A nice yellow such as honey (girls like it) but this takes a tone down which requires a tinted glaze, such as brown or even deep red, (your local paint department should have pamplets on how to do it yourself. ) I know it sounds crazy but ive seen it, NICE.. My final thought is to to take something in your design of the room (example the color of a shirt in a picture on the wall, or a less noticed color in the comfort set) and paint one wall that color, perferable one that has the window or windows or big furniture up against it and then pic a earthy tone that is a lighter shade.. If I sound crazy, than my other answer is to go to the paint store and gather some pamplets on painting.6. How to paint a table from light wood to dark wood color?If they have a glossy finish you will need to sand them. Just get sand paper and rub it evenly everywhere to get off the finish. The you need to stain it and seal it with polyurithane. That will give it the shine. Hope this helps!.7. What is barycentre and how does it work?Instead, two celestial objects orbit each other around their common center of mass, or balance point of a system. In astronomy, the center of mass of two or more celestial bodies is sometimes called the barycenter.This kind of interaction happens because the force of gravity is mutual. As one celestial body pulls on the other, the other responds in kind until a balance point is found.Let's demonstrate the concept of a center of mass with a couple of familiar examples. Grab a ruler from somewhere. Try and balance it on your finger. You will need to place the finger smack in the middle of the ruler to balance it. That's because its center of mass is at its center since it's a uniform ruler. Neither end is heavier than the other end.Contrast this with a hammer. If you put your finger in the middle of the hammer to balance it, what will happen? The hammer will tip and fall over. Make sure it does not hit your foot on the way down by the way!This happens because the hammer's center of mass is somewhere else because one end is made of heavy metal and the other is of light wood. You will need to place your finger really close to the heavier, more massive metal end, in order to balance the system, so to speak. Thus, the common center of mass is very close to the metal end in this example. In some cases, like a box or ball, the center of mass may actually be inside the object itself.What these two examples should've taught you is:Two celestial bodies of different masses will balance at their common center of massThe center of mass will be located closer to the more massive object
