Ultra cheap auto-on LED moonlights

You are trying to grow corals with a moonlight? You are right...you guys are way out of my league. I only want a small amount of light to simulate the moon. The nightlights I have look like a cool white/blue light similar I figure to the look of the moon underwater (as I recall from the last night dive on the reef).

I think he's confusing actinic lighting with moon lights

I put one of these lights on my 58g, they work great
