I personally like to provide a nice fluorescent light for all of my burms and large snakes. Do they need them to survive? Perhaps not, but I have noticed that my burms are far more inquisitive, active (but still spending long periods contently coiled), and seemingly content in cages that have a nice light cycle. These same cages are heated by a pro product radiant heat panel. Our large burms are in Habitat Systems cages that measure 12' x 4'x 3'; rockword side walls, two sided viewing windows, the works. Of course, I know plenty of people who keep their burms in cages with no lighting and they do just fine; I suppose it could come down to a quality of life issue.
