simple on this i hope,
i have a simple disco light in my games room, a 50 watt halogen light (12 volts i believe) shines onto a parabolic shaped disc covered with coloured mirror tiles, the disc rotated in time with the music, and projects a swirling pattern of light on the wall and floor.
i'd like to keep my power consumption low as all my machines pull a fair few (hundred of) watts each, so i was thinking of replacing the halogen bulb with a led array.
i'm guessing i need to be thinking of luxeon type led's, but what light output leds would i need? distance from the bulb holder to the mirror is about 3 inches, then it's reflected light is shone through a lens behind the bulb holder, so i imagine i'll need a few led's to cover the entire mirror surface (about 4 inches in diamiter)
