1 Watt (Warm-White) LED with Heat Sink

Make a 1 Watt LED flashlight or a headlamp with this ultra-bright LED. The LED is very bright, with the 140-degree Lambertian pattern. Compared to most LEDs, you would say this is 17,000 millicandela. Either way, it's incredibly bright! The output is a 'warm white'2900K.
The LED is mounted onto an aluminium 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.
