I recently added two 48" ati bulbs to my 3 ais sols for supplementation. They were kits that I had to wire myself. They ran great for about two weeks and the other day they just shut off. When I plug the ballast in the first bulb turns on for about a second then goes off, the other bulb does nothing. Does anyone here have experience with these? Can someone point me in a direction as to where I might start? Should I just pull the who;le thing down and try re-wiring everything. Thanks all, Todd.
