With the older model BMW’s, they use one bulb to light up two rings per headlight whereas the newer BMW models use one LED bulb per ring. Please view the diagram below:As you can see, the bulb near the left powers up both rings from one location. The inner ring will get majority of the light since the bulb is right behind it. The outer ring is further away and the light has to travel a longer dis...

8. How Can I Measure LED Power Output? The easiest way to measure total power output is to position the LED very near to a large photodetector.You should be able to get large area photodiodes from: Vactec, EG&G, Hammamatsu, IPI Centronic, Optodiode, Silonix, among others. The last one is a Canadian co. Solar cells OK, but you should probably do a rough calibration. Here's one way to do it: Noonday...

2. How Hard Can I Drive LEDs? Q. I'm interested in driving my IR LED to the maximum power without significantly reducing it's life span. I've heard that i can drive an LED above its rated power if i do it in pulses?A. If you actually need 50% duty factor, you will find yourself limited to just double the rated continuous current for the LED, usually about 50mA. For best results, get an AlGaAs IR ...

What color should I get for my LED’s? We have a variety of colors to choose from, but we highly recommend getting Xenon White for the color. Xenon White is also the brightest color that is available.From the brightest to dimmest, it would move from Xenon White – Ultra Blue – Brilliant Red. Since Xenon White is the closest color to natural sunlight, it is the brightest light color. Ultra Blue is cl...

LED strips are strips of LED chips that are encased in a silicon material that are typically used for accent lighting and other “add-on” type lights. They can be used to the interior and exterior of the vehicle and they can be tapped to any 12v power source on the vehicle. LED strips are usually used to achieve the Audi Style Daytime Running Light effect and to provide ambient lighting inside or o...

Can I cut my LED strips into shorter lengths? Yes, our single-colored LED strips can be cut every three (3) LED chips to make it shorter. Our dual-color LED strips such as the switchbacks cannot be cut shorter.Please understand that cutting the LED strip will void the warranty and void the return/exchange on the item. We recommend that you test the LED strip prior to making any type of modificati...
