Here was a reply fr hillbillyreefer who tried them:

They are a PITA on a tank. I've got 4 on my 33 gal. You'll need a 10 amp powersupply for each bulb. You'll need to figure out some sort of reflector. The ballasts get really hot and burn out quickly. I think they would be better in a car as the airflow would keep them cool. Not sure how long the lamps themselves last as the ballasts all fried before the bulbs. The light is decent and the bulbs are available in various K ratings. I never did take pics of them when they were running, it's too late now.

Save your money and buy a MH, way less hassle and better life span, in my experience.
