skyedolphan,
Would you be buying this to get both the LED moonlights and cycle/intensity controller? The cycle/intensity controller is a neat idea, although I have no idea if it would actually benefit the captive reef. If you are getting this primarily for the LED moonlights themselves, you can build (or have them built) for MUCH MUCH less than 90$ + 5$ shipping. I think I spent a total of $7.76 on my DIY moonlights - 3 LEDS, 3 resistors + a 12V power supply and some wire that I had around hanging around. Throw in some heat shrink tubing, a little electrical tape, just a touch of solder and VOILA - moolight. The tank looks really cool with the LEDs lights on. But, of course, I don't have the ability to control the lunar cycle/intensity with this setup.
Just throwin' this in.
