Halogen bulbs work similar to a spot light though the beam cover more distances and not so fixed on one small area. Do you know if they touches the bulb, andee?
Ryker had aged to 12 months by then, he stopped screen climbing once he reached 8-9 months of age. With the halogen he was the normal suggested 6-8 inches away. He burned himself from trying to warm up. The thing is he had a heavily planted cage but there was not shade in the upper regions where he would bask (which is how most keeper keep their chameleons) I no longer keep my chameleons like that. I provide partial shade in the upper basking areas within inches of a small sliver of full basking light. But go a an inch or so lower and it's mostly partial to full shade. My chameleons have completely nature replicated cages.
If Janet hadn't mentioned it I would have, veileds are found in more mountainous regions (usually) and therefore it's more temperate and covered in shade/trees compared to the hotter regions of Saudi arabia. The real thing is, basking out the general temperature is different than a basking zone in a cage. We usually don't have 90 degree ambient temps in a house/cage, while outside they easily can warm up enough with basking and a correct ambient temperature and will move quicker. With a single basking light trying to warm things they will burn quicker.
