The real key is the basking temp. Most folks inside provide a MUCH TO COOL BASKING SPOT. Usually these are around 100 degrees when in actuality many lizards including Cyclura get much hotter than that and not only like it but need it. In effect uv light is NOT nescessary if the lizard can get hot enough. F. Retes has said that for years with Varanids and he is correct. I'm including temp gun pics taken on a day when it was partly cloudy and around 80 degrees. You'll see the lizard is 112 degrees but still attempting to warm up. The highest temp I've recorded was 125 degrees with them still basking but with their mouths open to disspel heat. Remember shade is ALWAYS available. What you need is a range of temps from about 75-140 degrees and let them choose what temp and at what time they want to be at. At night, of course, heat lights should be turned off......TC
