Is it totally exposed to the elements?


Including insect infestation. Intrinsically safe units are meant for
gas tight operation, so these are the best units to get for their
outdoor IP ratings. Look for something with an IP rating of IP65. They
are sold with seal packs of washers and stuffing glands to keep
everything out of the fitting. Even if the cable entry is to be made
through the back of the unit to hide the cable, make sure you seal it
from the elements and insect infestations.

I was just pondering - as you do - that a 4 foot fluorescent totally
exposed above a front door would look hideous. If, however, it was within
a porch of some sort where you only saw the light from it, fine. But then
wouldn't be exposed to the elements.
I've got four 2 ft ones exactly like this, but they're ordinary tubes
behind a custom made diffuser - with the electronic ballasts indoors.
