Thought I'd share this little tidbit here. Driven with four Lux 3s in series.
Unsure if these guys are overkill but at the moment, it does look quite nice.

Get a shimmer in the water that I can't get with the flourescent lighting during the day.
Supposedly moonlight is around the 470-480nm spectrum. The units I got were binned at 460-465nm. Boo. Hopefully the fish won't notice any difference. Though I am kind of curious if anyone knows how important getting that 470-480nm range is.
