Top 10 Led Light Questions

Considering that led light may still be new to many people, we provide ten common questions and answers about led light for you to get started.

1. How long does it take for an LED light to start saving you money?

wow you spent that much on a led light.....!!!!! you got ripped off, my led light was 10 bucks!!!!

2. Does an LED light bulb need a power supply?

yes, it needs a power supply. If you are baffled by this simple question, you are NOT ready to tackle this project

3. Why are there light rays coming out of the LED light sources?

It is caused by optical defects inside your eye. It affects all light sources in the dark - consider the traditional "star" shape with points when in reality starts are round

4. I bought a led light for my car HELP?

look for a red wire under your dash. these are usually constant 12V. If you do not feel comfortable doing this you can run a wire from your battery, just make sure you put a fuse in the line somewhere so you do not melt the wire and start a fire. for a ground you can just clean the paint off of bare metal somewhere and screw the ground wire to the metal, make sure there is not anything on the other side of where you are drilling though. the switch you get should tell you which terminal is the power input and which is the ground. The last one will be the ouput to the led

5. Assessing the Impact of Different Light Sources on Product Quality During Pharmaceutical Drug Product Manufacture – Fluorescent Versus Light-Emitting Diode Light

Pharmaceutical scientists are often asked to assess the impact of modifications to the illumination in the manufacturing and product packaging environment on product quality. To assess the impact of switching light sources, four model compounds were exposed to standard fluorescent light, LED, and "yellow light" and the extent of drug photodegradation was determined. Photodegradation under LED light is generally reduced compared to fluorescent light and is often predictable if the UV-Vis absorption spectrum of the active pharmaceutical ingredient (API) and the spectral power distribution emitted by the various light sources overlap. However, lack of noticeable spectral overlap does not ensure absence of API photodegradation and may require additional assessment for selection of appropriate lighting conditions. A detailed evaluation of the API and solid formulation absorbance was performed to assess degradation risk for Compound A and Vitamin D when exposed to LED light. The light budget was established for Compound A, spanning all stages of the manufacturing process, under different illumination conditions to enable a complex supply chain. The results also demonstrate that while LEDs used in manufacturing areas are generally "better" compared to fluorescent lights, they are not replacing yellow lights for compounds sensitive to visible light.

6. Where can I find quality LED light bars for my car?

Try to compare more and get the very one.

7. What company would be able to run an LED light inside a glove (cable) with the light source coming through the?

here are 4 sites hope one is there you can use, bless you

8. anybody know a good led light kit for a 09 ninja 250?

What would you want an illegal blue light for? CMVSS 108 for canada, FMVSS 108 for us, ECE R53for EU, I am not sure the other countries, dictate what colour, location and intensity for lights on your MC

9. Does The T-Mobile Samsung Dart Have A Notification LED Light?

yes, it has that light... Good luck!

10. I have a basic LED light kit, help! Electricians would be nice here?

assuming you wont want them on all the time, they can be wired through a switch so they can be turned off. if the wires are connected to a fuse as above answer, then thru a switch, it can come on with the car, or be turned off

11. Homemade led light bar ideas?

Could get them at auto stores, but do your really want the cops to book you for illegal lighting?

12. does anybody know the laws in michigan regarding led light kits?

They do not like them and no kind of led strip can be on when your moving

LED Light Flux Over a Bacterial Plate Surface
First of all, to avoid misunderstandings, let us set some definitions according to SI terms (re. e.g. to this Wikipedia article) For a point-like source, the power irradiated within a cone with vertex in the source will be constant, and the Irradiance therefore will decrease with the square of the distance from the source. Or equivalently, the power emitted within a steradiant (Intensity) is constant. Now if you have a diagram (normally given in polar form) of the relative Intensity, that shall mean that the total power irradiated by the led is given by the following integral for $phi$ ranging from $0$ to $pi /2$. $$ begingathered P = int_;0^,pi /2 I_0 (R)I_r (phi ),2pi Rsin phi ,R,dphi = hfill = I_0 (R),2pi R^,2 int_;0^,pi /2 I_r (phi ),sin phi ,dphi = hfill = P_0 ;int_;0^,pi /2 I_r (phi ),sin phi ,dphi hfill endgathered $$ where $P_0$ is the power of the led if it was radiating with a constant flux equal to that in the vertical, i.e. with $I_r (phi)=1$. Otherwise, knowing $P$, then $P_0$ will represent a scale constant. That premised, the sketch above shows clearly that the power emitted inside the solid conic angle of aperture $dalpha$, which is $P_0 ;I_r (phi ),sin phi ,dphi $, on the plane at distance $h$ will distribute over a surface of $2,pi ,ho (phi ),,dho (phi )$. Since we have the following relations: $$ left begingathered ho = h;tan phi hfill dho = frach cos ^,2 phi ;dphi hfill endgathered ight.quad Leftrightarrow quad left begingathered phi = arctan left( ho /h ight) hfill dphi = fraccos ^,2 phi hdho = frach left( h^,2 ho ^,2 ight)dho hfill sin phi = fracho sqrt h^,2 ho ^,2 hfill ; hfill endgathered ight. $$ the relative Irradiance (irradiance per 1 totally emitted W) on the plane surface will be: The above relative Irradiance shall be then multiplicated by $P_0=I_0(R) 2 pi R^2$ in order to get the value in $W/m^2$. Note that $I_0(R)=Q(0,R)$ as should be expected.1. Advice on LED light periods for cactusMost cacti are happy to have "growing season" in summer and a "resting season" in winter. After all, in their natural environment water is unlikely to be available all year round for continuous growth. When they are dormant in the "rest" period, light levels and high temperatures are not so important - though clearly you need to keep the temperature above freezing. Even temperatures that dip below freezing wo not necessarily cause any damage provided you do not have daily freeze-and-thaw cycles, which are guaranteed to damage them.Many cacti can deal with quite high volumes of watering in summer and grow fast as a result, so if your objective is "quick growth" giving them a rest for 4 to 6 months each year might not be as bad as you imagine2. Solid blue LED light on Blackberry torch?Sorry, but I have never seen the blue light before. Only the flashing red light. It could be water damage. Try putting the phone in dry rice to absorb the moisture, I've heard it works great. :)3. My computer mouse LED (Light) glowing even after shutdown.I am using Vista,Pls help?If its a gaming mouse or has led's in the mouse like razors have then no, there is no way to turn that off, its getting a direct feed of power from the usb port, which means yes you have to either shut down your computer or unplug your mouse4. would puttng a long led light tube on a bike be illegall?The LED lights are probably not illegal, but red and blue might be. Those colors suggest a police vehicle, which I suspect is not your situation. Consider a mixture of colors that would not be mistaken for any emergency vehicle. That would include red & blue, red & white, and all red5. Is there an LED light bulb that will screw into a regular light bulb socket?extremely tough thing. look in a search engine. that could help!6. Will a CFL bulb fix into a led light fixture like the ones you find in ikea?Ha ha ha no no no you need a new fixture

LED Light Maintenance - 6 Tips for Seasonally Repairing/Maintaining Your Deck, Dock & Landscape LightingIn this post, we have put together 6 tips for checking your LED outdoor lighting system. This will help you ensure that everything is working efficiently and at its best. Check that all your lights are functional, it's much easier to know what is not working when the entire system is powered on. Check the output voltage of your transformer, anything less than 11vDC would require attention. Replace any burned out LEDs, using the same wattage LED. Increasing wattage can overload the circuit and decreasing it could increase the voltage going to your other fixtures, causing them to burn out prematurely. Bury exposed cables, in high traffic areas it may be common for cables to make their way to the surface. Ensuring all your cables are buried will reduce any trip hazards and prevent rodents from chewing through them. Checking for loose connections, if a light is dim or flickering you may want to double-check and see a cable is loose or has gone bad. Adding dielectric grease on connections you find that are loose. Dielectric grease will help fight corrosion and ensure longevity in your connections. Clean lenses and brush off fixtures. LEDs are known for maintaining a cool temperature, most LEDs wo not get hot enough to melt snow. Depending on the size of the fixture, you can use a toothbrush or broom to brush off any excess snow that may be piled up on your LEDs. Doing this two times a year should make your system last for many years and not keeping up with basic maintenance might cost you big in the future by forcing you to replace multiple fixtures and or/ multiple cables. Unsure of how long your warranty lasts? Not up to doing the maintenance yourself?3. I have a basic LED light kit, help! Electricians would be nice here?assuming you wont want them on all the time, they can be wired through a switch so they can be turned off. if the wires are connected to a fuse as above answer, then thru a switch, it can come on with the car, or be turned off4. would and led light strip from pepboys that runs off a 12v batt work off a wall outlet?No. You will need a 12 volt DC power supply that runs off of house current (which is 117 volts AC)5. Need an LED light array or something like that with AC power for miniature model house?Check out partsexpress.com6. What is the rightmost LED light on my nintendo 3ds?Nintendo 3ds Lights7. Can I drive a led light with help of a CT clampYes, this is sometimes done in industrial situations to indicate the presence of current in a circuit. It's a bit of a waste to use a measuring grade CT for an indicator. If the CT is made with very thin wire and much less core then it will still be sufficient for powering an LED and may not need a series resistor. It's typical to use a bipolar LED (the two-leaded LED package contains two dies of the same color connected back-to-back) so the LED conducts on both halves of the AC cycle. You could also use a bridge rectifier LED or a put a diode across the LED and throw away the negative half cycle, or put two LEDs in inverse parallel. Here is a typical commercial product: In this case, the maximum current through the core is 100A and it turns on at about 1-2A. By looping a wire through the core more than once, the range can be moved downward by reciprocal-of-integer factors. For example, three loops through would make the LED turn on at 0.30.7A (1/3) and allow a maximum current of about 33A in the wire.8. led light strips power consuptionThe reason you are getting such low amperage is because you do not have the strip resupplied with voltage at every voltage drop point. If I am getting this correctly you have the whole strip hooked up to one end resulting in the voltage dropping to probably somewhere around seven through nine volts on the other side. So if you re-inject the 12VDC power source every 1-2 ft you will see a higher current.
Stay Safety Compliant with Emergency Led Light Bars
Whether you operate a construction company, run a private ambulance company, run a utility provider, or have a towing business, you likely have a fleet of vehicles that you need to get the job done. Did you know that there are federal and state safety standards that apply to these cars, trucks, and SUVs? In fact, both utility vehicles and tow trucks are required to meet a number of standards before being used on a job site or dispatched to a customer in need. One essential requirement is lighting, and, for these work vehicles, some lights are required while others are forbidden. Be certain to keep your vehicles compliant by knowing when you can and must have a grill light, flashing light, or Emergency Led Light Bar . Federal Requirements on Lighting There are two federal regulations that dictate the lighting allowed on roadside and private emergency response vehicles. The first is the Federal Motor Vehicle Safety Standard. This law is executed by the National Highway Traffic Safety Administration (NHTSA,) a federal agency. It is this particular law that dictates what is required for a brand new vehicle. The other relevant law is found in the Federal Motor Carrier Safety Administration (FMCSA). This law doesn't provide much information for those constructing these vehicles and new purchasers but does have a lot of influence on what lighting is allowed on the truck or car after it is in operation. When it comes to the FMCSA, the most important thing to know is that a lot of modifications you may want to make are actually prohibited. By way of example, the color of lights on your tow truck or utility vehicle cannot be similar to those used on police vehicles or ambulances. Therefore, only these vehicles can have a specific emergency LED light bar, while a roadside construction vehicle will need to utilize one that only has white or yellow lights. Additionally, the Society of Automotive Engineers and Department of Transportation will regularly provide advice and information to manufacturers and owners of these vehicles. At times these recommendations haven't aligned. In the worst instances, there have been direct discrepancies. For this reason, it is imperative to discuss any after-sale modifications with the manufacturer or a lawyer knowledgeable on these issues. Requirements for Utility and Construction Vehicles Set by the State Remember, there are not just federal standards to meet when it comes to your emergency and response vehicles. In many regards, the lighting requirements for towing, utility, and similar vehicles are designated at the state level. It could be that your utility vehicle or towing truck needs a version of an emergency LED light bar, without the red and blue lights, to be compliant, or it may only be a grill light that is allowed in your state. You might be allowed to place red lights on the rear of your light bar in some states, to indicate that it is the back of the vehicle, but not in others. For instance, in Texas, tow trucks are prohibited from the use of red lights, other than tail lights. While most states discourage the use of blue lights as well because this is the color of EMT vehicles, in New Mexico it is perfectly fine to have blue lights on your LED light bar. If you look at some of the northern states, such as Alaska and Minnesota, don't be surprised to find that blue lights are placed on snowplows. As you can see, it is essential that you check your state's laws regarding the color, shape, and placement of additional lights before you buy! If your EMT or private ambulance company needs to upgrade its safety standards on trucks, cars, or other vehicles, your utility van needs a grill light, or your construction truck needs a stick light , you will find the lighting you need at Ultra Bright Lightz. We even have bulk deals to offer you the best deal on the safety lights you need!

Polar Sapphire: Driving Down LED Costs
Polar Sapphire's proprietary process produces the world's lowest cost, highest purity alumina. High purity alumina faces growing demand, driven primarily by the growth in LED lighting market - but secondary (and highly disruptive) demand may be created by emerging markets like sapphire smart phone glass (see Apple's recent announcement relating to sapphire ingot production), lithium-ion battery coating, etc.High purity alumina - 99.99% pure aluminum oxide (Al2O3) - is used to make artificial sapphires. Sapphire ingots are cored, then sliced to make the crystal wafer substrates on which LEDs are grown. Higher purity alumina yields larger wafers due to the smaller number of impurities in the core ingot. Larger wafers drives down the cost of LED production.The market for high purity alumina was near 14000 tonnes in 2013 and is expected to grow to 25000 tonnes by 2015. Market prices remain near $50/kg - leading to an addressable market of more than a billion dollars by 2015. Polar's high-margin, low-cost (and low energy) production method will ensure it's position as the lowest cost and highest quality provider in this market.Currently building a production line large enough to demonstrate core economics and initiate strategic customer engagement. Our first investment was placed in 2012, and we recently led their B-Round in Q4 2013.

URPOWER LED Light-up Blueooth Speaker Review
I've had a fascination with Bluetooth speakers that light up for quite some time. One of the speakers I've really had my eye on is the JBL Pulse because of its fluid motion with the movement of the LED lights. This one from URPOWER mimics that style of motion and color that the JBL Pulse puts out. It's not built as a cylindrical tower, but is instead a small square style speaker, which is actually a little more convenient.URPOWER's Wireless Stereo Speaker with LED Lights utilizes Bluetooth 3.0 Technology. It promises to connect to your device within about three seconds of setting the speaker into pairing mode. Connection was very simple and quick and it amplifies the sound of your mobile device very well. There are very few Bluetooth accessories that I've been able to pair so easily.The speaker appears to be very durable and even somewhat water resistant as all the buttons and ports are covered with the silicone covering that encases the speaker. That is not something that is indicated by the user manual or even the description on Amazon, but having used other 'all-weather' speakers, URPOWER's Wireless Stereo Speaker with LED Lights exhibits some of the same qualities as those devices.I paired the speaker with my iPhone 6 and was quite impressed with the volume I was able to get from it. This small portable wireless speaker has a nice depth of sound with punchy bass and has easy to use controls. The forward/back controls even control tracks within apps like Pandora. There is a pause/play/answer button and a mode changing button, too.Now, even though it's a Bluetooth speaker, it comes packaged with a 3.5mm audio cable so that it can be used with non-Bluetooth devices, too. The speaker charges with the aide of a Micro USB cable, which is also included.One feature I was a bit leery of was the LED lights. I've seen a lot of speakers that incorporate LED lights, but many of them have dull, lifeless lights. That's not the case with this URPOWER speaker. It has a a very vibrant array of colors and there are seven different modes to choose from.This is a very nice speaker and is affordable within its category. Not only does it put out nice sound, but it also provides a fun light show.BUY ON AMAZON: Hi-Fi Portable Wireless LED SpeakerOriginally published at www.macsources.com on November 3, 2015.·RELATED QUESTIONI didn't get Google Glass Explorer Edition.

How Are LED Lights Compared to High-Pressure Sodium ( HPS) Lights?
Before LED grow lights , HPS( High-Pressure Sodium Lights) were the main sources of light used for indoor plant growing. But, after LED lights were introduced, HPS lights started losing their popularity and demand. In actual LED lights are more efficient than HPS ( we'll discuss it later in this article) but still not everyone prefers LED grow lights. Maybe due to some sort of confusion regarding Are LEDs actually efficient in plant's growth? Isthis electricity saving appliances? and so on.LEDs have been proved better than sodium lights in most of the aspects,and that is why these are gaining popularity with each day gone. So, without confusing you further let's have a look at the working criteria of both LEDs and HPS grow lights:1: Power ConsumptionThis is the foremost thing one should look before buying a grow light. Growing indoors itself is an expensive task and spending too much money on faulty grow lights can take your price out of your budgets fixed for the same. HPS lights are more power consuming,and this became the reason for the need of searching a power effective light. LEDs, on the other hand, consumes less power and gives more output which means their efficiency is higher than those HPS grow lights.2: Heat EmissionHPS lights radiate a lot of heat when working and thus makes it necessary to spend extra money for installations regarding heat sinking technology and air circulation. LEDs do not produce that much heat. They even can touch your plants without harming it in any way. Also, it is easy to throw out the heat produced by LEDs with just a minimal investment.3: Intensity:However, HPS lights are just a little bit good in producing intensified lights than LEDs. But as an approximate, LEDs also produce the same intensity which HPS lights produce. So now you can easily make a distinction between the two in terms of intensity.4: YieldHPS lights are lesser in yield than LED grow lights as the latter gives 3 times more yield/ output for the same 1W power consumption. This means your production from HPs lights would then become 3 times with the LED grow lights. This is a major plus point for the LED grow lights over HPS lights.5: DurabilityLED grow lights on an average have a lifespan lying between 50,000- 1,00,000 hours whereas HPS lights last for around 10,000 hours. This means you can enjoy years of service from the LEDs without facing any failure. This makes them more reliable than those HPS grow lights.6: FlexibilityLED lights can be easily adjusted as per the plant requirements which is not present in thecase of HPS lights. Most of the HPS lights remain fixed in their place without offering any specific adjustment facility to the users. LEDs excel HPS lights in this regard because they are more flexible to use.8: Type of LightLED grow lights mainly exhibits red and blue light spectrum which are considered to be the best suitable for vegetative and flowering stages of a plant. HPS lights, on the other hand,emit all the wavelengths at once without giving attention to any specific wavelength or colour.This is the reason why their efficiency is good than the typical HPS grow lights in general.So, this was a comparison between the two in nearly all the aspects one looks before buying any of these grow lights.External Links:-Growerslights.comTwitterWordpressPen.ioGravatar·RELATED QUESTIONI didn't get Google Glass Explorer Edition.

Infrared LED Light Therapy - Information About Infrared Technology
Over the past half of a century there has been a big push to be healthy. People are always looking for new and innovative technology that can help improve the look of their skin and body. Many products have been developed to give people the care that they are looking for. One particular product that is very popular is infrared led light therapy.This infrared therapy provides people with the benefits that infrared light rays offer. Because the light rays are absorbed into the skin, it is commonly used for rehabilitation and a variety of different ailments. One of the most popular injuries that this technology works with is soft tissue injuries. The infrared lights help to boost the bodies overall blood circulation and also promotes the white cells levels.The increased levels of white soft blood cells and circulation allow this technology to heal injuries faster. You will often see health professionals using this technology to work on people who have sports injuries. Because the human body is made up of over 90% water, the led light therapy and help to activate and ionize these molecules.Unlike traditional heat therapy that requires a hot pad or hot towel, this technology is less uncomfortable then traditional heat methods that are used. Additionally, infrared led light therapy works very well in beauty treatments. It can work well to reduce scars, wrinkle lines, and improve the overall skin texture and look. You will often find that many different beauty spas use this infrared technology as an intricate part of their treatment.
$6 Led Interior Light Conversion 12v Dc Car/boat/rv
This instructable might give you some ideas of how you can use inexpensive, off the shelf, LED lights to convert your car, boat or RV, interior lighting system. For about $5 US, you can buy a ready to use 12V LED light. Istarted with an amber side marker light, which included three bright amber LEDs in a ready to use device. My ten year old Suzuki/Chevy's interior light had been on the fritz for almost a year. Replacing the bulb didn't work; the time delay pwb (shown later) was bad, so I had a good excuse to do the LEDconversion. The completed light is really nice. The amber light is easy on the eyes, and yet there's plenty of light to fill the car's cabin.A few assorted observations...Current draw of old incandescent bulb =0.8 ampsCurrent draw of new LED conversion = 0.05 ampsLED Side Marker = Blazer International #CW1586A $4.97 USD**These lights sealed, which adds a few minutes to the job. If a suitable unsealed light is available, the unit will be easier to take apart.Many people will have the odds and ends on hand to complete the job, but Ithrew in an extra dollar for solder, wire, etc...Disconnect NEG battery terminal or pull the appropriate fuse and remove the lighting fixture from the vehicle.Remove old bulb & holder, but take a look at the wiring and contacts; they may come in handy.With my car, the dome light was a bit more complex than some. When the light was working, it had a time delay and fade-out which Iactually found annoying. This added feature required a small circuit board, whichhad to be removed. The sliding switch was still good and allowed the typical DOOR/ON/OFF choices.If you're unfamiliar with how most automotive interior lights work, you may want to pay attention here... Most vehicles use negative or ground switching for interior lights. So when you open the door, that little button switch that turns on the light actually provides a path to ground, or the negative side of the battery. If your light has a sliding switch like mine, that switch is probably providing two possible paths to ground; through the door switch and directly to ground, thus providing light when the door is closed on demand. Slidinng the switch to the OFFposition, simply blocks any path to ground or the negative side of the battery. (More about this in the next step)I used much of the existing wiring, metal contacts, and hardware for the new LED unit. For an explanation of how the sliding switch works, see picuture details.I used hot glue to attach the LEDunit and stabilize wiring, etc...Actually, this was an easy job. It took longer to make this instructable than it did to do the project. This picture was take without flash, and although the three LEDs appear to be separate points of light, the actual light output is very even and more than adequate for the purpose of lighting the car's interior at night. The amber light is pleasant to the eyes too.
