Also, Can they really see red light!?! If so that kind of makes me mad as I bought that light specifically to use 24hrs if possible just to provide heat if needed. I plan on not using heat lights/heaters at all other than the UTH when my Herpstat comes in though, the long one at 90-92 should keep the tank in a nice 80ish overall,a nd I have 75 watt nightbulb I can use for the hot side if needed.
