Hey everybody, I am looking into a project that involves placing a 30w LED set inside my old projector (to take the place of the burned out bulb). Problem is, i would like to very the brightness of it as it may end up being too bright for the projector (the light that was in it was rated at 1400 Luminous). Here are the states of the LED:
I have been trying to find a linear potentiometer capable of handling the 15 to 18v's with a 30watt but am unable to find such a thing. What all would i need in order to very the current between the 15v and 18v? I guess if i can not find any potentiometer to do this then i could always run the LED at 15v so it would have 1500 Luminous.
Anyways, i'd love to hear some suggestions on going about doing this since i can not seem to find anything myself.
