I have a 40' x 40' shop, with 10 eight foot flourescents. I just swapped them out for the smaller. single pin bulbs and electronic ballasts: they will light at zero degrees. It doesn't usually get that cold here in the swamp, but the humidity was giving me fits with my old bulbs.

I broke my shop into four sections, for lights. I do have some mounted on the wall, at about 10' (roof is 14') and it all works good.

Good luck!
