I have a 32 x 32 x 9 (ceiling height) detached garage that I use for my workshop. It has insulated walls with OSB covering the insulation but the ceiling is open to the roof decking. I'm going to put 7/16 OSB on the ceiling and blow in some cellulose. Right now it has a mis-mash of florescent tubes and the ballasts are bad on about half and the other half won't light when it is below 40 degrees. After pricing bulbs and ballasts I'm beginning to wonder if I'd be better of putting up all new fixtures rather than fixing the old ones (they have to come down anyway when I put the ceiling up). Looking for ideas/alternatives to the 48" tubes. CFLs? Halogens? Other? LEDs are too expensive for lights that may only be on for 10-15 hours a week. While I'm doing it I'm thinking about installing a couple receptacles in the ceiling too. Right now I have only one for the garage door opener. Since the ceiling is 9' and I can't reach it without dragging out the stool or ladder would it be better to install one in the center with a cord reel (that's what I'm doing for air)?
