I have an "exo-terra" red night time bulb that i used to use in my terrarium. would it be okay to use at night in my fish tank? can the fish see the red light? any 'bad' light in it, i.e lots of uv rays?
you can use it, and I actually don't think fish can see it, or at least see it very well. I would suspect it wouldn't have any UV concerns as red is on the it's on the low frequency end of the visible light spectrum. someone please chime in and correct me if I'm off base here at all
fwiw, most people use weak blue incandescent bulbs or more popularly blue LED's for moonlight as it's more of a natural color than red would be, but it's pretty much just personal preferance anyway. :wink:
Thanks for the reply, i know reptiles can barely see red light so thats why i used it for my terrarium. And i would go buy moonlight LED's but i dont have money right now and had this red bulb laying around so i just rigged it to the back of my tank, hoping it would be okay to use it.
