Not currently using ceramic heat emitters.
I have 3 heat sources - 1 daytime lamp on the hot side; 50W. 1 nighttime lamp on the cold side (that stays on constantly, even during the day so as to maintain level ambient temperatures); 50W. And 1 Large UTH from ZooMed stuck under the hot side hide.

I will look into the accurite thermometers. After I get advice on what to do here I plan to make a run to pick up the appropriate supplies.
