Not sure where you got that from. The key to any lighting is the bulb. Have you noticed that bulbs for the hobby are more expensive than similar bulbs used for other applications? Even the cheap ebay bulbs aren't much good. I doubt those bulbs will provide the required spectrum over time, at least not in an efficient way.

So you can get a 30W unit for $90 which only included the bulb and ballast and you need to run some inefficient power supply, what about a reflector? Oh right they don't make one. Also you can get a 70W MH bulb and ballast for under a $100 if you know where to look, that way you get more than twice the output and a proven spectrum. Did you know my SPS corals get great polyp extension when the lights are off?

I just don't see any reason in pursuing this, sure if you want a 5.5g but not much of a market there and anything bigger would benefit more from a 70W light.

You're going to have to hook up a PAR meter and measure these lights before you can make any claims.
