I agree, looks exactly like burns from a light...Exactly what UVB tube do you have, and what Basking Bulb do you have? (wattage, color)
Your "Basking Temperature? of 80-95 is very troubling, as Dragons need a Cool Side Air/Ambient between 75-80 degrees f, a Hot Side Air/Ambient between 88-93 degrees F, and then an actual Basking Spot/Platform SURFACE Temperature between 105-110 degrees F, which must be measured with either a Temperature Gun or a Digital Probe Thermometer, as no Stick-On Thermometer can measure a Surface Temperature...Without a high enough Basking Spot/Platform Surface Temperature, a Dragon cannot properly digest his food. Also, you should be trying to replicate natural sunlight over the Hot Side of his tank by placing a long UVB tube right alongside a bright-white colored Basking Bulb, so that they are both sharing the top of the Hot Side of the tank, and then his Basking Spot/Platform should be positioned within the Hot Side of the tank, directly underneath both lights, so that he is absorbing both lights at the same time while basking...Something is not quite right here..
UVB lights generally will not cause burns like this as they do not emit enough heat, however, if he's right up against one for a long time they could burn him too. Usually though burns like this are caused by the Dragon being far too close to either a Basking Bulb or a Mercury Vapor Bulb.
