I've had several from petsmart that were red and they always blow after a few days. While I was at wal-mart getting house bulbs, I noticed they had a night time heat bulb. So, I got it.
Well, it puts out heat and does a great job except for it's a black light. Will this interupt night time behavior?
I use them for my toads, map turtles and for one of my guinea pigs(my house gets cold at night).
