Hello,
We do need to know the type & brand of UVB you are using? Is it a flourescent tube bulb or a compact or coil light? You mentioned that you have a basking bulb, of a 100 watt, is it a bright white light or a colored light?
What do you mean your dragon is sunburned? How close is the basking light to him?
What type of thermometers are you using, are they the round stick on type of thermometers? If so, they will not be accurate at measuring the basking spot temperatures. They will measure the ambient temps pretty well.
If you are not giving any calcium then she may have early symptoms of metabolic bone disease, especially if you do not have a very good
UVB light.
Let us know how things are going.
