I actually had Halides on my 46 bow for a long time, but eventually went to T5HO's. Metal Halides use waaay to much electricity, and run very hot. I had a hard time in the summer with overheating in my tank, and couldn't afford a chiller. I switched to T5HO's, and love the output and effiency.
I have no experience with LED's. I just cannot see how those diodes give enough light penetration...
I have kept LPS and Softies with no problem for the past year with T5HO's. I haven't tried SPS, but I know people who successfully keep them with T5's.
