I installed 3 of the screw in ones in my canopy and and hooked them up to a old power wheels charger and they work great. I have some pics and I'll get take some more at night to see them in action. The only bad thing is they didnt have blue just red and green so I got the red ones. BTW thanks again for the info on this. Heres a pic of the screw in one I got.[IMG][/IMG]

By the way, many of your critters cannot see red light, so you can use this to your advantage... let's say you have an unidentified predator in your tank, you see?

I would recommend to put a series resistor to the LEDs; in cause any spike in voltage won't kill the LEDs.
