To start, my BP is doing well in his cage, and seems to be a happy camper.

I have a 60 watt blue bulb and a 75 watt red bulb. Both are labeled "Nighttime" bulbs. The red is somewhat red-orange and I've been using it during the day and the blue at night...only problem is the blue doesn't keep the ambient temps warm enough. Cool side will be low 70s and warm side high 70s. He does have a UTH however, and it's on a thermostat at 102 degrees. The red bulb is perfect and keeps ambient temps in the 80s.

Question 1) I've read everywhere that constant overhead lighting is stressful to snakes. If that's true, how do I keep ambient temps up at night? Also, why are they labeled "nighttime" bulbs.

Question 2) Is red or blue light more likely to be bothersome? I'd prefer to keep the red on all the time for ambient temps and not have to swap out every night. If I leave the red on all the time is that bad or stressful?
