What do you guys personally think is best as a heat source a basking light bulb, heat ceramic emitter, heat wire, etc...?
I currently have a Heat Ceramic Emitter (of coarse somewhat distanced from the screen) but don't know if it is correct or entirely wrong?
Glad to see you're asking questions.
Too often people have been given really bad advice on how to care for their cham , by places that really should know better and then the cham gets sick, etc.
During the daytime, your cham should have a basking light and a UVB light.
The basking light can be an ordinary household lightbulb.
At night there shouldn't be any lights but a ceramic heat emitter is OK if the night temps are less than 50 degrees for a Veiled.
A temperature drop at night is actually healthy for chams, since that's the way it is in nature.
