Does the high bay lighting have to have some kind of protection on them due to physical damage???

Its definately a good idea. I think it may be required for HID since the lamps get hot. Or maybe its because the outter lamp envelope is necessary to block the UV rays.

Not sure if its required for fluorescent. I've seen fluorescent fixtures in gyms that don't appear to have any protection. However, there are also sleeves that cover the lamps and contain them when they break.

I think the NEC will have to catch up with the times here. All the newer school gyms and the like are moving on to T5/HO fixtures. Of course common sense would dictate gaurding but it seems it is not specificaly required for a flourescent fixture.
