Can you use the red bulb 24/7 in the winter?

I'm kind of worried that my tanks are cooling down too much at night. I've been adding 40 watt infrared bulbs during the day (in addition to the UTH) and I'm wondering if I could keep them on during the day. They don't seem to be eating as much lately.

Yes, you can run red lights 24/7. I have a red light that I run continuously.

I do too (red light that runs continuously in addition to the UTH). They are probably not eating as much also because of the colder temps inducing brumation...the gecko form of hibernation.
