how do i change a white led to have red output like red leds...? can i put a red film over it to make it more red?

desolder the white LED's, trace the circuit to the resistors for them, desolder the resistors, solder in proper resistors for the new LEDs (red LEDs have the lowest voltage/amperage requirements, so they need different resistors), solder in red LEDs, have a beer.

i know i can do that but would there be some kind of dye/clear paint to use over the white leds..

what would the point in that be? you would lose so much output and the color wouldn't be truly red...

you can't really filter led light. like if you have white leds behind a red lens, they will barely be visible.

what about red led's behind red lense? That works right? You have to just match up the filter color with the led color

yep. matching frequencies is best.

cause you have to remember, leds are only one wavelength. So if you filter it, you're left with nothing, unlike incandescent lighting.

ahhhh.. i see, i guess i'll have to replace all the leds then..
