I want to make something that runs around 1000lm. I was thinking of useing XMLAWT 1000-Lumen LED Emitter White Light Bulb (3.0~3.5V) from DX and house it in a Ultrafire Flashlight Aluminum Alloy Casing/Shell/Housing with Strap - Black (also from DX) but I don't know what kind of reflector or driver I should use? Any Thoughts.
