These are the 3.5in fan & light controllers. Thay come with 2 blue cathodes and has an inverter built in. I'm planning on getting the silver model but I do not want the 4 blue leds that light up the knobs. I plan on replacing them with 4 white ones.

Anyone know exactly what size and voltage the blue leds are? No guessing please, I want to know for sure.

edit:
ANYONE?????? I just wanna know what led to use for this thing. If nobody knows, ill just remove the leds and use it withought any lighting. That wouldn't harm the thing, would it?
