I was at one of the local pet stores in Fresno, California and I noticed some very nice aquarium light fixtures. Some with white and blue and some with a variety of color combinations most with remote controls.
Yes, they're a couple bucks more than the average enclosure light, but the LED's now are very nice. Also, it appears you can program these for day and night time lighting.
There are even ones you can program to the region of the world you're herps or fish are from so they're on the same schedule right down to cloudy vs sunny days and more.
Wow!
