One way to do it by switching bulbs from one side to the other. It's pain to do, but you'll know forsure what he problem is. I went with an amazon ballast for $50 and it's been working for over a month now. I messed up though and bulb some aftermarket bulbs. Ended up buying 2 lights, but for some reason one side is brighter than the other. Not sure if it's the bulb or ballast that caused this, but I'm going to leave it be for a while.
I'd bet on it being the difference in ballasts causing the difference in output. There are tests on YouTube showing output differences in multiple 35 watt ballasts as well as some higher wattage ballasts.
