radiation perhaps, in the "ultra-violet radiation" part of "UV" but since reptile enthusiasts spend hundreds of thousands every year buying special bulbs with types of UV in them, i would highly doubt that this is a "harmful" radiation. radiation is just a term for anything being "radiated" out of.. well, anything. i use blacklights on many reptiles that i want 24/7 heat on, it simply does not provide a night/day light cycle. blacklights are even sold FOR reptiles, its harmless.
