Hey melbell,
The new light that came with the set-up I bought from Craigslist had LED lights on it. They look beautiful, but are a little annoying because they don't turn off ever, unless I unplug the whole light. The first night I had my two GSPs in their tank I just left the LEDs on, and it seemed to stress them out a bit--I didn't notice them sleep at all, just paced the glass all night. (caveat: there could have been any number of many many things that were stressing them out that night), but I started unplugging it at night, then having bluelight for a bit in the am and a bit in the pm, sort of like dawn/dusk thing. It looks like you've got a awesome way to create LEDs on your setup, but if you ever go shopping for a light that has them built in, I'd look for one that lets you turn them off (I assume those exist?).
I'll post pics when I get my camera back (lent it away for the weekend)
