I have three troffers for drop ceilings. $15 each or all three for $40. Fully tested and working. Removed from a remodel. Three T12 bulb - can be wired to switch on 1 and 2 bulbs separately. All ballasts work. Bulbs are included. The fixtures are in good shape, presentable, and the diffusers are clean and crack free. The covers for the ballasts/wiring are included. I evidently didn't have them installed when I took the pictures.
