Has your cham taken it's first shed on you yet? Before we self diagnose metabolic bone disease and over exposure to uvb, could this just he the begining stage of it's first skin drop?
Keep track of the temperatures and don't worry about your bulb, your bulb is fine.
This myth has been debunked and pursued in court to the bitter end ans near death of eco and zoomed. unless you are buying redistributed whole sale crazy namless brand lights from god knows how to pronounce this country o companies name... In which case your chams death is on you...
Burns are possible with a bulb that is functioning perfectly fine, linear or compact makes little difference.
Put black tape on your probe and measure the radient temp of the hottest possible place your cham could get. If the temps go above 105 you are risking serious injury to your cham. Move the bulbs higher or ditch the reflector and add a small pc fan to help vent the heat up.

I expect humidity to be a factor in this particular skin condition, however I am not confident in my knowledge of vield chams. Zilla makes a great chameleon skin conditioner and moisturizer though...Thought id throw that out there
