tek light issues (ballast?)

[kien]

I had this happen recently with my T5s. Thought it was ballast but I tried putting in fresh bulbs and that fixed it. Seems by bulbs were just blown even though they were only 8 months old. I'm not sure why but if one gues on a particular ballast they all seem to go. This would suggest to me that they are in series, which seems odd to me if that were the case. I honestly have no clue how they are wired as I've never openned mine up. At any rate, you could try fresh bulbs :-)
