Will keeping while light on all night cause any issues?

I just had to get a small space heater for the snake room, which is kind of ridiculous considering we only turned off the AC last week (I swear Phoenix is some kind of cosmic joke). I got a really nice/safe one off amazon for $40 delivered that has a built in thermostat. That, combined with a $25 humidifier (Honeywell warm mist model from Target) has turned the spare bedroom into a snake friendly little jungle environment that I no longer have to mist twice a day.

Infrared or black night bulbs work very well for running heat 24/7. I use both for my 10 and 20 gal long. For your 20 gal long you can use either, but you'll have to have a 75watt red bulb or a 100watt black night bulb. The red bulb is stronger and puts out more light to view your animal(s).

I use a ceramic heat emitter, mainly because they last forever and the one I have has a crazy awesome warranty. But other then that I would try the infared bulbs. They're fairly cheap and keep the tank nice and toasty. Plus, you can get a cool red ambient glow, if your into that kinda thing.

I totally forgot that I had a 75 watt red bulb tucked away :rolleye2:. Got it setup on a timer with a dimer switch, now it's nice and warm in the tank.

Thanks for reminding me of what I had :D
