I just use 4 foot fluorescent lights in my shop area. I have 37 of the two bulb 4 foot fixtures in the basement. Once in a great while the fluorescent bulbs die. But its rare. And the bulbs cost $1 each or something like that. Fixtures were about $10 each maybe. They just run and run and make lots of light. Sometimes getting high faluting and fancy dandy just does not make sense. In your case it would have made lots more sense to just put in one or two of the single bulb fixtures with a pull chain. They are $1 each and dead simple. 110% reliable. 5 hours of on time in a whole year? Why not go for simple and reliable and cheap? Why F around?
