Hmm. Never heard of a drop grid ceiling being used for an outdoor parking canopy. Nice to see them using T12. I would have used vapor proof fixtures though.
Yeah we have a few here , some use 8' slimeline lamps in vaportight light fixtures the 60W flickers somewhat in the winter even with a cover!!
Also if the T12s are run 24/7 they won't go out , even if the ballast is 50F minimum starting temp! Better to use 40W lamps not the 34W junk and keep all 4 lamps and cover on to keep the temp up in cold weather and they should be bright
There's an installation just like this in my city with a drop ceiling , it looks good
This setup looks horrendously underlit. Let's leave the fluorescent troffers and drop ceilings for inside the building and use metal halide or high-pressure sodium lighting in parking garages
