I'm thinking aboub exchanging the 55W/12V car bulb of my hand spotlight. It is powered by 12V 4Ah.



My first idea was a 10W DX module with reflector and a 75mm lens. But I think it won't be bright enough.



Second idea was the 30W module with a step up converter.



But i'm not sure if it will be really bright.



Does anybody already tried these modules or has someone a good idea which emitter will be right for such a project. Should be really bright and have a acceptable runtime (minimum 1 hour).
