Here is a diagram of the temps these bulbs give off and most of us wouldn’t use a bulb with that kind of power for a Cham. This is why I assume your thermometer is inaccurate unless the basking bulb is 20 inches away from the basking spot. That’s a little over a foot and a half from the bulb, in that case I guess you would use the 150w bulb. Just be careful it could burn your Cham.150w bulb is what I use for my beardie I can send the lighting diagram that keeps reptiles basking at 100 degrees+ within 10 inches of the bulb
