3 WATT LED LUXEON W/ HEATSINK, Make a 3 Watt flashlight or a headlamp with this ultra-bright LED.
The LED is very bright, with 90 Lumens in a 140 degree lambertian pattern. Compared to most LEDs, you would say this is 30,000 millicandela. Either way, its incredibly bright!
The output is a 6000K pure white. The LED is mounted onto an aluminum PCB for heatsinking, and it also makes it easy to solder in. Simply connect to the big + and – pads on the PCB (there are two of each). The best way to drive these LEDs is constant current, 350 mA, but you can get away with under-driving for compactness. At about 3V, the LED draws 200 mA, so connect two Alkaline batteries up directly with no resistor for a basic bright lamp. You can also try driving it directly with a 3.3V power supply, that will probably work OK as well (although its not ideal) – that’s what we did when we made a vintage LED bike light using a 1W white LED.
