Can't speak for the effects (or lack thereof) of black or red lights on BPs, since I don't currently keep BPs, but have a number of other snakes, some of whom appear
to love the nightly basking (they always have UTH too) under these "lights" (dimmed, of course). I've been using them for many years for snakes that like & use them,
I see no issues whatsoever. Personally I'd ignore their hysteria, & avoid posting about whatever brings it on.
BTW, I know of no "official" research on the subject...only people's opinions. My snakes tend to live long healthy lives too.
