I've been playing around with LED's and I think they will work very well for that...the blue is a 470 nanometer and really lights the place up and can be run as low as 3.5 volts. The white ones show promise (I was told they are 8-9000K) they are awfully expensive right now.
I think the LED"S hold a LOT of promise for us...specially small tankers...
we'll let you kow when we get changed over and are ready for a tank party....
