I have a Reefbrite Hybrid MH/Led Pendant. I used it for 3 weeks after buying it brand new from PA. When my sump leaked, I took my tank down and have never used it since. I also have the radium 20k mogul bulb that only has 3 weeks use on it as well. You would have to get a ballast, as I no longer have that. I used this light over my 93g cube and it was perfect for coverage.
