My ODNO is doing great. Heating issues are the only problem I have had. If you can find a ballast (and fans) for cheep, then ODNO is the way to go. Just make sure that you get good air-flow accross the entire bulbs.

OK enoght of that- I just got done listening to my friend D tell me how she had to shut down one bank of her ODNO fixure to prevent an algae outbreak in a new tank- because she had TOO MUCH LIGHT!!!. Seriously. Why didn't you guys make me aware of how cheap and powerful this stuff was earlier. It costs me $30 to replace a 6700K 34" CF bulb. I could do the same thing at 15-25% of the price, with cheaper bulbs if I only would have known. Seriously, it's OK to smack me upside the head once in a while! DANG!!!
