I think all species probably benefit from UV (both A and B), even nocturnal/crepuscular species.
I also firmly believe that, as is so often the case with this hobby, we have taken that idea way too far. It is rare for any species to be out in the blazing sun all day every day. Further, UV levels wax and wane depending on the time of day and the weather conditions. So why then do we insist on pumping animals with the highest continuous levels of UV that we can fit in an enclosure from lights on to lights off?
I like seeing that Arcadia has started stepping down in UV levels, I believe that will actually benefit animals in the long run.
Next, I would like to see keepers starting to modify light schedules so that the UV bulbs are only on sporadically over the course of the day. I run all of mine during only a three hour window on a randomized on/off schedule.
