A couple years ago I put a bunch (7 ea) of the cheap 'shop' flourescents in my work shop . (48" twin bulb). I also fitted them with the cheapest bulb that the store was selling.
I don't heat my shop in the winter and each winter, fewer and fewer of these bulb will light. I noticed today, that only 2 of the 14 bulbs are working (temp. has been down to 38 deg.)..
I figure it is time to do something. My question is; is it the ballasts or the bulbs that are failing?? It cost about half the cost of a new fixture, for a new ballast and then there is the work of replacing the ballast.
Is this a common problem with flourescents in a cold climate?? Should I try a more expensive light?? Or would these lights last longer if I used a premium bulb??
Experience, opinions??
