Hamilton Technology 4 Ft Lighting System and IceCap 250W Electronic Ballasts The setup was purchased in 2009 and its in excellent working order with only a few scratches here and there on the metal housing. It's been rewired from the original setup to run 250 watt MH bulbs using IceCap ballasts. The VHO bulbs use the stock HT ballast. The 250W bulbs had about 7 months of use for about 3 hours a day before I shut the tank down. The VHO's need to be replaced. I'm also including two unused 175W bulbs that came with fixture before it was rewired. $150 for HT system and the IceCap ballasts.
