1 Watt (Blue) LED with Heat Sink

1 Watt (Blue) LED with Heat Sink

1 Watt (Blue) LED with Heat Sink

Make a 1 Watt LED flashlight or a headlamp with this ultra-bright LED. The LED is very bright, with 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 'cool' 6000K pure white, not a 'warm' incandescent-looking 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.
