i use a 100w basking bulb and a 26w 10.0 uvb light for my 4month panther cham
and it works well.. the 100w basking bulb seems a bit too hot though, I had to move mine a bit, 50-75w for basking in my opinion incase you were wondering
Just make sure to have hiding areas if using 10.0 bulbs. Keep closest branch at least 12" away. A UVB meter would be a good investment if using the 10.0, also.
