I believe its the luminax factor in certain lights - luminax is good and no where near equivalent to being outdoors even on a dull day, but 'blue' light type in computers and some bulbs are bad for duping the brain especially if have sleep disorders or stress to begin with. The UVA in bulbs for reptiles is different type of light as opposed to our LEDs as they can not see very well with normal bulbs - contradiction I think but that's what I was told. I cant stand these new humanoid LEDS they flicker but a lot of people don't seem to see it.
on a tortoise positive I swear these Arcadia combined are the same as happy health SADs lights sunwise. I love them being on as they give out heat and brighten up the room and will bet money they are same as the SADs lights giving out UVA&B. CB
