I don't have ceramic heaters, but this is what I have for my girl.
3 lights; two for daytime and one for night.
Cool side day is a 75 watt bulb; hot side is a 150 watt and I have a heat mat underneath.
(My room is on the cooler side)
The middle one is the night light for warmth at 50 watts.
Temps run at 70-75• cool, 80 warm (middle) and 90 hot side. Her vet's recommendations; this is for a 40gal breeder.
Hope it helps!
