I am looking for lighting options to put in our barn that is effecient, but bright.
The lights will be installed approximately 18' above the barn floor. The barn is approximately 30X40, and is not heated. We are also looking for lighting for our garage, which is a 2 1/2 car garage with approximately a 12' to 14' ceiling.
The cheapest and most convenient solution for both the barn and the garage is a simple and cheap 4' T8 fluorescent fixture. I have installed the high bay fluorescent fixtures in a basketball gym at 25' above finished floor and they have worked out great. The best thing about these fixtures is; the lamps and fixtures are cheap, and readily available. If you should choose a HID fixture, for the barn, they are more expensive and they do not turn on instantly like a fluorescent.
