I've been reading some about the problems that people are having with certain brands of UVB lights (mainly those Reptisun 10.0 compact flourescents, but there are others as well). Briefly, the term given to the condition that reptiles are experiencing is photo-kerato-conjunctivitis, which is compared to "snow blindness" skiers can suffer when not using sunglasses. One particularly interesting hypothesis given for at least some of the problem is that some of the newer bulbs on the market are being made with a new phosphor, which contains a very different light spectrum than more classic bulbs (i.e., the Reptisun 5.0 and 10.0 flourescent tubes, the ExoTerra Repticlo 5.0 and 8.0, for example). The different light spectrum, and not the total amount of UVB being given off, is being looked at as a cause for the eye problems.
