I have four, (6") in-line air cooled bulbs installed in a 10x10 tent. #1 = 1k, #2=600W, #3=600w, #4=1K. My problem is that bulb # 2 will fire, but burns itself out after an hour or so. Another hour or two later it will fire back up for another hour before it burns out again. This has been repeating over the past week to 10 days (ever since it became hot outside). My question is...do you think it is a bad bulb, an electronic ballast issue, or temps as air is being sucked through the air cooling ducts? Any help most welcome. thanks.
