I Have a 60 Watt Equivalent Led Bulb That Takes 10 Watts Can I Use That and Leave It on All Night in

Watts are units of power. Lumens are units of light. An incandescent bulb will use 60 watts of power to create about 450 lumens of light. An LED bulb will use 10 watts of power to create the same 450 Lumens. Incandescent bulbs use much more power because most of the energy is turned into heat and not light. LED bulbs convert most of energy to light and only a little to heat and are usually cool to the touch. In short, the lamp rated to operate a 40 watt bulb will easily operate a 10 watt bulb with tons of capacity to spare.

1. Led Bulb Flicker when duty cycle is below 40%. What is wrong with circuit?

This looks like a mess waiting to catch fire or electrocute someone.You do not say where this is, but almost certainly some part of the AC line is tied to ground somewhere. That means you have a hidden conduction path from somewhere in the "AC Supply" block to the source of both FETs. The only way the concept is valid is if this "AC Supply" block is a completely isolated secondary of a transformer, but that's a long way to go to light a LED.If this thing is still working at all, then the reason it might be flickering is because of a beat frequency with the AC line. You did not even mention the PWM frequency, so it seems you did not think about it and it could therefore be a issue.

2. can i connect an 1.2v LED bulb to a 1.5v D battery(in a battery holder)

1.2 Volt Led

3. Can I plug my 110V/2W/a7mA LED bulb into my 250V/660W lamp?

The wattage limit indexed on commonplace table lamps are often based on the thermal means of the lamps reflector head, the thermal means of the lamp socket, the thermal means of the twine terminations or the insulation on the twine or twine providing the lamp. The score is a optimal fee as set by using UL standards, to sidestep kit failure and hearth destructive factors. utilising an more suitable wattage bulb ought to reason a hearth or harm to the table lamp. Use of a CFL will possibly no longer help if the warmth generated by using the ballast exceeds the thermal score of the table lamp fixture. With CFL's it truly is not basically the lamp that generates warmth however the ballast additionally. it truly is advisable to envision with the table lamp producer before utilising a CFL.

4. Why does the LED bulb outside my attached garage take several hours to turn on?

Why does the LED bulb outside my attached garage take several hours to turn on?How many is "several"? If it's 24, it's broken.Does it have an internal light sensor? It may be waiting for it to get dark.Why does the LED bulb outside my attached garage take several hours to turn on?.

5. I got this LED bulb in my house that stays lit on(bright)/off(dull-phosphor)?

you need an electrician to check that out........that's dangerous!

6. Led bulb lights up even when 1 wire is connected. How?

internal capacitors are charging on the positive half cycle of the AC wave, and discharging on the negative half. Very small amount of current. But Since leds will light up at very low currents, they turn on.As mentioned in the comments, this will only happen if you only interrupt the neutral wire.

7. Strange behaviour of a LED bulb via SSR Relay: it's EMI?

I do not know what kind of electronic testing equipment you have. Basically you will want to put a low pass filter on the power line tuned between the primary frequency and the second harmonic. Better would be to put a band pass filter at the power line frequency, a tuned circuit at the power line frequency. But that is a real pain to get adjusted properly without a frequency counter and the lower frequencies are probably not causing the problem. Ferrite are fine, but put many turns of wire around and through the ferrite to increase the inductive reactance. If you know a ham radio operator, you can ask for assistance in choosing the components for a good filter. The ham may even have the diagnostic tools to help diagnose and fix the problem

Why Does Low Power Factor Make My LED Bulb and Clock Radio Flicker at 0.2 to 3 Hz?
Likely problem: The computer psu is almost certainly running in a "burst" mode, drawing a short pulse of energy occasionally. This is for less than a mains cycle and/or not synchronised to the mains waveform, so the waveform is arbitrary & non sinusoidal with random shape, so many harmonics are produced and power factor is poor. The filtering on the other devices is not adequate to remove the harmonics. Possible solution: Adding a load - maybe via a USB port (fan / light / coffee warmer (higher power) ...). If the USB ports are powered up in this mode then you can probably tailor the load to keep the psu in non burst mode - and waste a few watts in the process1. Will this 20,000k LED bulb function as a grow light?A 20,000K lamp will have peak output at 145 nanometers (Wien's Displacement Law). That's hard ultraviolet. It will hurt your plants. 10,000K still peaks at 290nm, UV. You want a lamp with a far redder color temperature. Here's a nice graph of the wavelengths plants like: See the page Light and Plants2. I have a 60 watt equivalent led bulb that takes 10 watts can i use that and leave it on all night in a 40 watt lamp?Mike's answer is correct but does not answer your question. The LED bulb is actually using only 10 watts, thus lower current and would be safer in the fixture rated for 40 watts. You should be able to leave it on for extended periods with no danger if everything is as you have stated. To be safe, check to see if the socket is getting warm after an hour or so. I leave some like that on 24/7 with no problem3. How do i make a simple LED bulb flash on and off ?The basic concept is a power supply (battery), a switch, and a resistor. How complicated you want to get beyond that is up to you. Although I could understand it's not real fun to run the switch by hand for very long. Beyond that you get into more circuitry; anything from a 555 timer, all the way to playing with a pic-processor like the Arduino which is very popular. It should be easy to find example circuits and even videos.4. How do I make a battery-powered lamp? If it's a LED bulb, could I do it with ONE AA battery?Yes and No ,, A high powered led just one will produce as much light as a 60 watt light bulb ..somewhere around 800 lumens ..it will seem brighter because it's generally more focused but if you shot the beam into a diffuser like a frosted opaque plastic looking lightbulb it would look pretty much the same ,, The down side is ....NO a AA battery wo not do 800 lumens . it takes a serious battery to give you that much light An 18650 battery is a cell like the ones in your lap top battery pack or the ones that the tesla roadster /electric Lotus sports car uses (thousands of them ) The new flashlights use them , the battery is 18mm across and 65mm long and cylinrical so they call it an 18 65 0 18650 It has 3.6 volts basicly and that's like 3 AA batteries It's also a different chemistry ..it's a lithium ion battery like your cell phone battery (which is also about 3.6 to 3.7 volts ) it just has a greater capacity to store energy for a longer period of time because it's bigger than your cell phone battery capacity is measured in amperage . the 800 lumen light would kill the little AA battery in an a matter of minutes ,in fact it would not even run on a AA battery without a small curcuit board called a driver which electronicly boosts the voltage of the AA from 1.2 1.5 volts ...up to 3.6 .. here we are agin at 3,7 volts which lots of electronics curcuits seem to like ..certainly these high power led emitters do . the AAA has i/3rd the power of a AA battery .They are really lame And the AA has 1/3rd the power of a 18650 So this battery about the size of your thumb (if you have a long and fat thumb ) is the most researched and about the best our battery science can give us . We've sort of hit the wall so to speak .Any efficiencies as far as lighting needs to come from the new leds . No is the answer :)
What Type of Centralized Home Control Hardware Is Available?
What you're looking for is home automation. X10 is probably the most popular technology system for this, but that Wikipedia page lists a number of alternatives.To address your specific areas of interest:LED lightingThere may be pre-built solutions out there, but as you're already writing custom software, you may want to look into using something like the Arduino platform to control your lights. Done correctly, you should be able to get the effects you're after. I found a tutorial about how to do a simple LED system that may be useful.Speaker ControlThere are actually a number of systems out there for home media distribution, such as Linux MCE (it took awhile to load that page when I wrote this, but it did load without timing out). You may be able to use one of these, or work some of the code in from one to duplicate the functionality (MCE is open source). The most simple solution is to use small appliance computers that run a very lightweight Linux solution (like MCE) that stream from the base computer. There are actual streaming devices out there, but I'm not sure how well they would integrate into your automation/control software. If you literally just want to run speakers, you'll need multiple sound cards in the base computer to differentiate between the feeds.Automagical ApplicancesThis is where the home automation tech comes in. Using something like X10, you have the ability to flip switches, monitor their status, etc. There are appliances out there that will talk some of these languages, allowing you to control them remotely. A quick search turns up an Engadget article pointing out LG Thinq devices that are accessible via WiFi and ZigBee. If you program your software to speak ZigBee, you should be able to integrate these appliances. Given the number of different protocols out there, you'll probably want to find your devices, try to settle on devices that use one protocol, and then write your code to speak that protocol, but you can also work with multiple protocols if you don't mind developing for each. I believe Linux MCE supports a few of those languages, and since it's open source, you can expand it to support whatever you'd like• Related QuestionsWhy do warm white LED bulbs emit colored light?The semiconductor material inside any LED consists of two differently-doped regions which meet in a common junction. In the P region there are many more positive than negative charges, while in the N region the negative charges (electrons) are more numerous than the positive electric charges. When the P-N junction is forward-biased by an externally-applied voltage, and current starts to flow through the semiconductor material, electrons in the N region are imparted with sufficient potential energy to cause them to move across the P-N junction into the P region. Once the mobilized electrons enter the P region, they are immediately attracted to the excess positive charges in that region - the result of the mutual Coulomb forces of attraction that exist between opposite electric charges. When an electron moves sufficiently close to a positive charge in the P region, the two charges combine with one another in a process called recombination, where the electric potential energy associated with the Coulomb attractive force is converted into electromagnetic energy. For each recombination of a negative and a positive charge, a packet or quantum of electromagnetic energy is emitted as a photon of light, at a frequency/wavelength that is characteristic of/determined by the semi-conductor material - typically a combination of the elements gallium (Ga), arsenic (As), Indium (In) and phosphorus (P). Indium gallium nitride (InGaN) is used to make up the blue, white, true green, and UV types of LED's, and Aluminum gallium indium phosphide (AlGaInP or AlInGaP) is used to make the red, yellow, and orange types.LED's that emit white light are made by one of two different methods. The first method combines different (red, green, blue) semi-conductor materials on the same chip, with each material emitting photons of a particular wavelength/color and energy, which determine the color temperature of that emitted white light. The second method uses a blue LED with a phosphor coating, which fluoresces when the blue light from the LED shines on it, causing it to emit a yellow light. Combining the yellow light with the blue light forms a white light, whose color temperature is determined by the proportions in which the blue light and yellow light are combined,Follows is a chart showing the different color temperature of commercial LED's, and where those occur in the visible portion of the electromagnetic spectrum. LED's classified as "warm white" emit light in the 2500-3000K color temperature range,Why do warm white LED bulbs emit colored light?.------How to tell what is causing my breaker to tripIn most cases of getting a "bzzz pop" on a circuit breaker there is a 98% chance you have a direct short to ground and if this happens once you shouldn't keep trying. The only thing it does is cause further damage to your electrical system. The first thing I would do is to turn very switch to the off position and unplug every piece of equipment from the system. I would remove the panel cover and using an ohm meter or continuity tester to see if I got a "ring" between the load side of the breaker and the neutral/ground buss which indicates a short. Or you could just reset the breaker if you don't have any meters but remember you are damaging your circuit and the breaker. So if you do not get a ring or the breaker stays on, then you know it is not the receptacles or the switches. Now you know the short is after one of the switches and probably in one of your light fixtures. You can then go around and turn on each switch on until you get a ring. This will locate which lighting branch is shorting out and you have at least isolated the problem to a smaller area of the circuit. If you do get a ring or the breaker trips off, you know the short is either before the switches or at one of the receptacles. Experience would tell me to check the receptacles first. Shorts are easy to find since they are and arc flash and create a lot of heat. so there will be the smell of something burnt, melted wire, blackened residue and melted insulation. Removing lamps form light fixture really doesn't help especially in fluorescent fixtures with ballasts and LED's with drivers. These ballasts and drivers use energy regardless if the lamps are plug in or not.Isolating and locating where the problem is allows you to make better informed decisions on if its a simple fix you can handle or you need professional help.FYI - since you have already turned the breaker on let it trip multiple times. It may be a good idea to change out the breaker. It is probably not operating within allowable tolerances (laymen terms the contacts are burnt and the bi-metal trip material is damaged).Good luck------Are LED bulbs safe for enclosed fixtures?Heat is the enemy ofLED light bulbs. Though the LED bulbs may have a similar shape to incandescent or fluorescent light bulbs, the LED chips inside the bulb arent that different to the chips in your laptop or other electronics. For this reason they cant be used in microwaves or ovens, and some of the larger LED bulbs may utilize a passive heat sink or internal fan to keep the electronics from overheating. Enclosed fixtures that dont allow for proper ventilation can drastically affect the temperature of the LED bulb, causing it to overheat and shortening the lifespan of the bulb. Thats why some bulbs will tell you not to use it in an enclosed ceiling fan or fully enclosed porch light fixture. Today wed like to address some frequently asked questions about enclosed fixtures or enclosed fixture rated bulbs to help you get the most light out of your light bulbs.What is an Enclosed Fixture?An enclosed fixture is any fixture or application where the light bulb is encased in a way that does not allow for proper airflow or ventilation. This includes but is not limited to porch lights where the bottom is glass or plastic instead of open air, enclosed Mason jar light fixtures, and lensed recessed light fixtures.Can an Enclosed Fixture Rated Bulb be Used in Open Fixtures?Yes, just because a light bulb is rated for enclosed fixtures doesnt mean it requires an enclosed fixture. To use a bulb in an enclosed fixture, it has to be designed to handle the heat of the enclosed space. In the open air, thats not a concern. The other reason to buy enclosed fixture rated bulbs is to use them outside. You may have garden lights or fully enclosed street lamps that require an enclosed fixture rated bulb. Because the bulbs are fully protected from rain and other elements, the bulb does not have to be rated for wet or damp locations to be used in an outdoor enclosed fixture. Understanding which light bulb is rated for a specific application, whether it be outdoors or an enclosed fixture, is important for getting the most light from your bulb. Dont hesitate to give us a call if youre still unsure whether you need a bulb rated for enclosed fixtures------How exactly does Curiosity's floating bus work, and how does it continue to operate when voltage drops from 11 to only 4 volts?The term "floating bus" means the power supply is not connected to the rover's chassis.In for example a car, the body is used as part of the electrical circuit: the negative terminal of the battery is connected directly to the body. This means every electrical component needs only one long wire to the positive terminal of the battery, and a short wire to the nearest part of the body.In some cases, electrical components are designed with a metal housing that acts as the ground connection, so there's no ground wire at all.This all works well, with one exception: when a positive wire contacts the body, you get a short that can damage the electrical system. Although most circuits are protected by fuses, there is at least one high-current circuit that isn't protected: the starter motor.If you wanted to convert your car to use floating circuits, you'd have to replace all these ground connections with wires to the negative terminal. And you'd have to insulate all components from the chassis.As a result, when either a positive or a negative wire contacts the chassis, nothing happens.I'm not convinced the answer here is correct. The circuit shown there is the correct way to connect a non-floating circuit to a floating circuit. But in Curiosity's case, the entire electrical system may be floating, so you don't need this conversion. I haven't found a source that specifies this though.Either way, the voltage they measured was between the power bus and the chassis. This indicates there's contact between the bus and chassis.The power bus voltage remained nominal, I presume, or they would have mentioned it.A short between the positive and negative sides of the power bus would have been a much bigger problem, as this would have reduced the amount of power available to run the rover.The short did not threaten the mission:"The vehicle is safe and stable, fully capable of operating in its present condition, but we are taking the precaution of investigating what may be a soft short," said Mars Science Laboratory Project Manager Jim Erickson at NASA's Jet Propulsion Laboratory, Pasadena, Calif.A "soft" short is a leak through something that's partially conductive of electricity, rather than a hard short such as one electrical wire contacting another.
Are Household LED Bulbs Suitable As Supplemental Light for Plants?
I use led lights for a planted fish tank, and all of the plants have very high light requirements, and it works fine. Mind you- each fixture (I have two of them), costs around 175.00 dollars, but if led's can grow plants in 20 inches of water in an aquarium, I am sure that for regular plants- led's will do fine.1. Blues was one of the main factors that led to the birth of Rock and Roll.?Yes the blues petatonic scale was the basis of the petatonic scale.. Blues orginally came from africa to the western world.. i.e guitar, bass guitar, drums were used in africa to play folk songs. . It was the conversion of classical music that made scales that then made jazz then many american blues guitarist used the classical and jazz scales to help create modern blues in America in the 20's american blues is as old as jazz is to america.. then in the late 40 early 50 you had R&B... some R&B and early Rock & Roll.. musicians Elvis played blues and R&B, Fats Domino R&B, Chuck Berry R&B and early Rock &Roll, Buddy Holly country and Rock and Roll. .Holly and Berry came up with standards in early days of speed and thier chord progression.. the Beatles credit Fats Domino for thier sound..Elvis opened up music from early unknown black blues musicians he had heard at younger days he was influenced by that and country music also from early country music.2.

SMD Led Bulb - White
There are numerous parts and accessories installed on a vehicle. It is very impossible for one to get to know every piece of them quite clearly. Every item is specially designed for a particular purpose. As more people are going to purchase at least car, it is necessary for we to get a general knowledge of the automobile itself. Doing this will not only help us in choosing a car, but also give us the ability to maintain our car in good condition as possible as we can. For example, when your front bumper lip is out of shape in a car accident, you are probably able to replace it with a brand new one. It is not a piece of hard work.These parts make up vehicle's many complicated systems. Engine system, brake system, and drive line system are very complicated as they are composed of various parts with totally different function. Lighting system, however, is relatively simple by comparison. Headlights, tail lights, fog lights, side markers are all the components of the lighting system and they are indispensable to a vehicle. They perform different tasks but for the same task that is guaranteeing a safe driving. Headlights work to bring the driver illumination in low-visibility circumstances such as precipitating and darkness. Tail lights perform to let the vehicle seen by other vehicle behind to avoid unnecessary bumps or collisions. Fog lights are specially used on foggy days. Side markers are turned on to show the vehicle's turning direction.It is very good for you to know the lighting system well. When any light can work, you can check out where the problem lies: if the ballast of your HID projector headlights is broken? If the halogen gas filled in the headlight bulb can not produce bright light for you? If the tail lights needs shinning angel eyes to highlight the appearance...Anyway, renew them time whenever you find the problem.
Replacing an Incandescent Bulb with LED Bulb
When we talk about replacing an incandescent bulb with LED bulb, one question comes in everyone's mind: Is it possible to use a LED bulb that has higher wattage equivalent than the fixture I have?Well the answer is Yes, as far as the LED bulb uses less wattage than your fixture. If you see the label states "100 watt LED equivalent" it does not mean that the LED bulb is using 100 watts, it means the bulb produces an amount of light (Lumens) equivalent to a 100 watt incandescent bulb. When your socket says do not exceed 60 watts, it means the dangers of high heat output is associated with Incandescent bulbs.LEDs do not discharge the dangerous levels of heat. Thereby, if the fixture states "not to exceed 60 watts" and you want to use a 100 watt equivalent LED bulb, this remains safe to do.Why LEDs are so much efficient?Because LED bulbs or tubes don't use direct heat to produce light, where Incandescent bulbs give a much bigger spectrum of radiation since they are heating metal as the lighting source. An important question that often asked by people: "How can I know if my LED bulb will be bright enough or not?" When we deal with LED bulb brightness, we need to think about Lumens, not watts. As per general standard, 800 lumen LED bulb generate the same amount of light as an old 60 watt incandescent bulb. Maybe you would like to use a bulb that is more brighter. So, for 60 watt fixture, you can use 100 watt, 125 watt or even 150 watt LED equivalent because as far as electricity consumption is concern all above mention replacement bulbs uses under 60 watt, and 150 watt LED equivalent produces about 2,600 lumens brightness, while only uses nearly 30 watt.It means you can use 150 watt LED equivalent bulb in 60 watt fixture and get three time or more than three time brightness of your traditional 60 watt incandescent bulb·RELATED QUESTIONWere can I get quality outdoor LED lighting for my landscape project?If short maintenance, eco friendly landscape lighting is a precedence for you, outdoor LED lighting is a ideal option for your landscape lighting design.

How to Power an LED Bulb Using Graphite
In this experiment, let us explore how graphite can be used to power an LED bulb. What you will need… • Pencil (6B, or any pencil with a graphite lead) What you have to do… • Take one of the wires and attach it to the negative terminal on the battery. The other wire should be attached to the positive terminal on the battery (or battery pack). • The other end of the wire attached to the negative terminal of the battery should be attached to the LED bulb. • Use the pencil to draw a rectangle on a piece of paper that is about 3 inches long and 1 inch wide. Shade the shape in completely. • The other end of the wire attached to the positive terminal of the battery should be attached to the graphite drawing. • When you complete all of these connections, the LED bulb should light up. • Try this with different shades of graphite lead. You can use different pencils with varying graphite lead and see what happens. What you just learned… Graphite is an effective electric conductor that you can use to complete a simple circuit. Even the thinnest layer of graphite, known as graphene, can serve just as well. Graphene is the thinnest material there is and is actually a single layer of carbon atom that has a honeycomb pattern. The simplest way to extract graphene begins with graphite - which is actually layers and layers of graphene. To do this, you need a pencil, a sharpener or cutter, tweezers and scotch tape. • Sharpen the pencil and separate the graphite flakes. You can also use a cutter to achieve bigger flakes. • Use the tweezers to place a graphite flake on a piece of scotch tape (about 3 inches long). You can fold the two ends of the tape so you have something to hold on to. • Fold the tape over the graphite and pull it apart again. Do this repeatedly and you will see a honeycomb like graphite on the tape. The thinnest part may even be graphene! This quality of graphene makes it an essential material in the development of nanotechnology. Researchers and manufacturers of computer chips have been testing it to see how its semiconductor qualities can be used to develop thin and flexible electronic components. How to Generate Current Through Human Battery? How to Make Batteries Out of FruitVolvo V60 Daytime Running Light - what is the bulb type? Instructions to replace bulb? Or what relay/fuse to replace?Before you go off to the Stealership to have the bulb replaced, you may want to see if the bulb has lost connectivity at the plug. Since these are LED bulbs, they do not go bad very often or very fast. I believe you should be able to access the plug by removing the main headlight in your car. While this video shows you how to remove the main headlight, it's a little cheesy. You should not have to remove the wire connectors to the headlight to get to the DRL. As far as the DRL, try unplugging/plugging it a few times to see if this rejuvenates the connection. Also, I doubt the problem is a fuse, since normally when you have two bulbs like this (as you do), both bulbs run off the same fuse/relay. Since one is working, you can rule this outCan a 20w12v halogen bulb work in a socket that originally came with a 10w12v? Do watts matter if volts match?Aussie gave you a good answer, so if you use the 20w bulb just make sure that the extra heat wo not melt your angelGrowing up back in the 1940,s I seen many home enema bags,and the bulb syringes in homes of friends etc?Does not matter the color. Mine were red, too, in the 60'sWhat is electricity in the sense that the same electricity that lights up a bulb can start a computer? Is it used for heat?Types of energy can be converted into each other.Electricity is very versatile. It can interact in very convenient ways with it's surroundings, more than other energies.Where as heat needs a pressurized system to add directed power and controlled higher energy output, electricity follows conductive strands (metal usually), gravity just does what it wants and blankets crap. So if I have not lost you yet, closer to the actual conversion difference between heat and light if the wave length of the em (electromagnetic) wave that us generated by electricity as it passes through something that is an obstacle, the lack of permeability of said obstacle is usually defined as resistance or impedance.In tern resistance and impedance generates an electromagnetic field. Now changing the current which you can think of as the speed of the electrons, determines the amount of em field potential. The more current the more energy is expended upon the obstacle. This allows something akin to a heat dial.Your body feels heat the most closer to the longer waves of the em spectrum (infrared typically when you feel it and do not see it ya know if you ai not in the blast radius of a nuke). Finally if you change the electron interaction between molecules or orbitals in the material that you are sending this current through, this affects the frequency of the electromagnetic wave meaning you can change the output from something like heat to light (although they are technically the same thing just a different wavelength).What is electricity in the sense that the same electricity that lights up a bulb can start a computer? Is it used for heat?
Do You Need LED Bulbs? Don't Worry We Got You!
Undoubtedly today's most efficient way of illumination and lighting is LED. Over the past several years LED lighting is being developed remarkably, because of this, it is considered the most efficient and eco-friendly way of illumination for residential and commercial places.The problems we've been going through about LED Bulbs, that they are not producing much brightness and consuming much energy. In the end, it leads to high-cost utility-bills. But now these both problems have been solved and a variety of smart LED Bulbs is been introduced for both commercial and residential areas."Make the Green Deal by installing these energy-efficient LED Bulbs"What are the Different ?In the past, the LED Bulbs is having a limited design to choose from. But at the pace at which LED technology is increasing is quite incredible. Because of the greater advancement in technology, you can now get a range of bulbs with different design and lumens efficacy. The cost is not too high and can provide a significant saving in utility-bills.A19 LED BulbsThe term A19 is used to describe the shape and dimension of the light bulb. An "A" is the classicLight bulb shaped, compared with an upside-down pear.The A19 LED Bulbs is also known as "general purpose" bulb, are one of the most common and familiar bulbs amongst all. It's a standard light bulb designed in a way that commonly finds everywhere.This bulb is one of the most energy-efficient bulbs, provides an omnidirectional light. Which means it provides the light in all direction, ensures the brightness at all the indoor space by eliminating all the dark-spot in your regular incandescent lighting.BR LED BulbsThe BR in these BR LED Bulbs stands for "Bulge Reflector". Which refers to the reflective coating inside the Bulbs, that directly emits the lights forward.If you are having a recessed can and looking for an efficient lighting solution.

In general, smaller frame sizes have higher nominal speeds than larger units mainly due to the larger impeller stresses in larger wheels. Mathematically, stress is directly proportional to the square of tip speed. With less denser materials, you can drive to higher speeds. A typical example would be an automotive turbocharger compressing air, made of single aluminum stages where 60,000-100,000 RPMs are not unheard of. The process gas compressor are limited to lower speeds due to a steel alloy makeup and practical constraints of rotor dynamics and thermomechanical stress in multi stage units.

Choosing LED lights by price are unreliable.To select suitable LED headlights, you can start from the following four parts.1. LED lamp beadsGood LED lamps use brand-new lamp beads and lamp bead chips matched by large-scale light source enterprises, with excellent materials, advanced technology, power saving, low power consumption, and good color rendering.2. Heat conducting materialsFor LED lamps, heat dissipation is particularly important to ensure the long life of the lamps and prevent them from being damaged easily. Poor heat dissipation leads to poor light and cannot see the road clearly. If it is serious, the headlights will be burned down.3. Cooling fanSome cheap LED lamps use substandard fans with low wind power and high noise.4. Power controllerA good power controller can not only meet the control function of the lamp bead, but also has a good protection function for the lamp bead, and complement each other with the lamp bead to maximize the service life of the lamp bead.If you want to know more about LED car headlights, you can visit my website (www.vantenled.com) or my blog (vantenled.blogspot.com).
Why It Makes Sense to Say Goodbye to Incandescent, CFL, Halogen Bulbs and Switch to LED Lights.
We can't emphasize it enough that the benefits of replacing incandescent, CFL, and halogen bulbs with LED lights are endless. They outweigh its competitors in many ways. Energy efficiency, durability, and better illumination being some of them.Victorian government is putting emphasis on installing LED lights because they are the latest advancement in lighting, and are a great alternative to your current incandescent, CFL or halogen bulbs.Here is a list of ways in which installing LED lights at your home can save you time, energy and money:Benefits of LED Lights:Highly Energy EfficientOn an average, 90% of the electricity used in a 50W halogen bulb turns into heat, which means only 10% of energy is converted into light. Whereas, LED lights use only 15% of the total energy consumed by a standard halogen bulb, and provide up to 85% better light output. And because they produce no heat, they reduce cooling expenses.Reduced Energy BillsLighting contributes a lot to your overall energy costs. Some areas of your house like the kitchen, bathroom or bedroom utilize a considerable amount of energy because of the frequency and length of time they are used. You cannot reduce traffic in these areas. What you can do is use energy-efficient lighting products in these areas to reduce the overall energy usage. Plus LED lights run on cool temperature when compared to standard incandescents and halogens, they save on energy costs occurring due to air conditioning.Long Life SpanLED lights have a super long life span of up to 50,000 hours, which means all your maintenance costs are reduced to zero. Plus no more burn out bulbs! If you have high ceilings and light fixtures beyond reach, LEDs are a perfect replacement because they don't blow up. On average, LED bulbs last up to 8-10 times longer than halogen bulbs, making them an ideal replacement option.Lifespan is directly liked to carbon emissions. A longer life span means lower greenhouse emissions because longevity reduces the requirement for frequent replacements - meaning need for fewer bulbs and hence fewer resources are needed for the manufacturing process, packaging materials, and transportation.DurableLEDs are durable because they don't have any filaments and glass components, making them resistant against vibration or breakage like old bulbs. This makes them a perfect fit for areas which are exposed to the elements. And since they don't produce any heat, you can install them in sensitive areas safely, reducing chances of fire.Instant OnLED lights deliver full brightness instantly, every time, unlike fluorescent lights which fade in and out or flicker every time you turn them on or off.Better Light DistributionLED have a better light distribution (focused light in one direction) as compared to conventional lighting which wastes energy by scattering light in all directions. This leads to dark/poorly lit corners or light in areas where it isn't required such as the ceiling. This means you can achieve much better illumination with fewer LED lights. Fewer lights reduce energy consumption, and hence lighting cost.SafeLED lights operate at very low voltage so are cool to touch and much safer to work with during installation and maintenance. Moreover, they can work just fine even if exposed to rain or snow.Environmentally FriendlyThis is one of the reasons why the Australian government wants every household and business switch to LED lights. The LED lights are an eco-friendly as they do not contain mercury or other harmful gasses, nor they emit any harmful UV rays. For example, a 10W LED bulb emits almost 60% less CO2 than a standard 40W incandescent bulb running 10 hours per day.Compact SizeYou can get LED bulbs as small as 2mm, making them perfect for areas where you don't have the liberty to use a standard size bulb. They can easily fit into hard-to-reach areas, and give an extra edge to the architectural features of your home or business.VersatileThere are many types of LEDs available in the market today. Replacement for every incandescent, CFL or halogen bulb is available to suit every need.If you want to switch to LED lights or want to learn more about the LED lighting solutions, please contact us today!Source: ·RELATED QUESTIONWhat times does Tribute in Light display outside of September 11, 2012?Located at West and Morris Streets in Lower Manhattan, the tribute of lights will begin at sunset of 9/11 (7:11pm) and fade away at dawn on September 12th (6:43am), though no formal service will be held.

How to Select the Most Appropriate Indoor LED Bulb Color
The pictures you supplied as an example represent unnatural colors in a forest being highlighted by artificial lighting. What you ask for and then show seems to represent two different things.Sometimes you have to buy a 3000k, 3500k, and 4100k bulb and see what works best for the location. Too low of color temperature and the whites in those pictures will fade, too high the whites will offend. The CRI (color rendering index) plays a difference too, if you have the option to pick a higher CRI the colors will be less distorted. A little history, if go back to an era that electric lighting was just Edison bulbs people picked colors of walls, flooring and furniture that created a comfortable look with the available lighting. When fluorescent lighting became available the initial locations for use was in warehouses and other commercial settings where color was less important than efficiency and often the greys and browns in a industrial setting worked better with a lamp that was more blue (4100k) than an Edison bulb. When one of those blue cool white bulbs is used in an environment with colors picked for Edison bulbs too much blue becomes highlighted in the space, and a warmer (3000k) color was developed to more closely create a similar effect as 2700K Edison bulbs.3500K is usually a pretty good neutral color, but we do not always decorate in the sames colors as 1950 so you have to look at your own interior colors. One house I lived in had kind of creamy tan carpets, matching paint, pine color cabinets and similar colored counter tops. The warm white lamps made it look dingy, 5000K lamps pulled the lighter tones out and made it more comfortable. House I live in now has all white baseboards, doors and casings. A 5000k lamp would make the the whites pop, and finger prints stand out. Also if somebody puts makeup on in a 5000k bathroom the goes to work in a 3000k office they may always look jaundice because they put too much yellow makeup on, or if they use a 3000k bulb for makeup and work outdoors they may look pale. You really need to light the room for it's use and colors.1. Can I install a 100W LED bulb in a car?I am going to assume that you are referring to 100/130W equivalent bulbs, not that they draw that much current. As long as the current draw is less than the stock bulbs you should be fine.Years ago I updated the 55W bulbs on my 525i to 80W bulbs and the additional current draw was enough to melt the wiring at the bulb. Those bulbs were actually drawing 80W, hence the melting. But LEDs generally consume less power for the same light output, so replacing conventional bulbs should not require any changes to the wiring2. Light intensity is dropping on large LED bulb display when it sequencesR52 and R55 are too large. With 24 big LEDs in parallel, you need 3 amps from your 12 volt supply. Call it 1.5 amps per PNP transistor. Because you want the PNPs to be hard on ("saturated" is the term), you should provide about 150 mA of base drive per transistor. That is, a good rule of thumb for transistors in saturation is that they are operating with a current gain of 10. Assuming 10 volts across the base resistors, they should be about 10 / .15, or 67 ohms. The value is not critical, so 50 to 100 ohms will probably work. And smaller is better. And make sure they can handle the power - use 2 watt resistors at a minimum. The 1k value which I recommended in your previous version was adequate for the much lower current requirements of your smaller LEDs, but not for these piggies. To put it another way, with 1k base resistors you get about 10 mA of base drive. If you assume a gain in the PNPs of 100, that only provides 1 amp per transistor, rather than the 1. 5 you need. Which is why the circuit works OK with only a few LEDs on - they are not drawing much total current.Note that this means your 12 volt supply should be rated for at least 4 amps. And you can get rid of the new caps, too. If anything, they add to the current requirements when the transistors first turn on.EDIT - And, of course, I did not think things through. A second problem is R51. As with R52 and R55, this is sized for a lower current draw. As given, a 1k R51 provides about 4 mA of base drive to the TIP31. Since the NPN also should be in saturation, this only provides for 40 mA of solid base drive to the PNPs, when they need 300 mA. Fortunately, the Arduino IO lines are rated for 40 mA of source drive, although the voltage output at this current level is not specified. The NPN needs 30 mA of base drive, and let's figure on 4 volts output at this level. Then 3 volts will be dropped by R51, and 3 /.03 equals 100 ohms. So replace the 1k R51 with 100 ohms and see what happens. My apologies for not thinking this through.END EDIT3. Strange behaviour of a LED bulb via SSR Relay: it's EMI?I do not know what kind of electronic testing equipment you have. Basically you will want to put a low pass filter on the power line tuned between the primary frequency and the second harmonic. Better would be to put a band pass filter at the power line frequency, a tuned circuit at the power line frequency. But that is a real pain to get adjusted properly without a frequency counter and the lower frequencies are probably not causing the problem. Ferrite are fine, but put many turns of wire around and through the ferrite to increase the inductive reactance. If you know a ham radio operator, you can ask for assistance in choosing the components for a good filter. The ham may even have the diagnostic tools to help diagnose and fix the problem
