Fkshiu: The current ballasts are at least 3 or 4 years old but I am not sure of the exact age since I bought the fixture used.
I have considered E-ballasts and done some looking at Sanjay's site, I am unsure how much a drop in Par will affect my tank, all of my sps' are up in the top 8" of water and I have no plans to populate the bottom with sps.
My other concern with E-Ballasts would be interference, I seem to remember reading somewhere that electro magnetic interference has been an issue with these, the ballasts would be about 4 feet from my profilux controller and 5 feet from the lcd tv/stereo/bluray set up. Any thoughts?
