Thanks for answering the questions so quickly...
Okay, so the thermometer that you have located on the Hot Side of his tank that is reading 105 degrees is just a stick-on thermometer strip? If so, then this is your main issue. I want to make sure that you're understanding exactly what I'm saying/asking here, as this can be confusing, especially for new owners. So just to clarify, you have 2 thermometers inside his tank, one on the Cool Side and one on the Hot Side, and both of them are some type of "stick-on" thermometers that are stuck to the glass of the tank, correct? And the one that is stuck to the glass on the Hot Side of the tank is the one that is reading a temperature of 105 degrees, correct?
If so, then this is why he's hiding out of the light, not basking, lethargic, and not eating, as his temperatures inside the tank are way too hot (not on the Cool Side, it's fine).
There are 3 temperature "zones" inside a Bearded Dragon's tank, and these are the 3 temperatures that you need to monitor. They are:
COOL SIDE AMBIENT (air) TEMPERATURE: The air temperature within the Cool Side of the tank, which should be between 75-80 degrees F maximum.
HOT SIDE AMBIENT (air) TEMPERATURE: The air temperature within the Hot Side of the tank, which should be between 88-93 degrees F maximum.
BASKING SPOT TEMPERATURE: The SURFACE temperature of the main basking spot/platform that is located within the Hot Side of the tank, and that is located underneath both the
UVB light and the Basking Light....Should be between 105-110 degrees F maximum for a baby/juvenile under a year old, and between 100-105 degrees F for an adult dragon over a year or so old. ********THIS TEMPERATURE IS A SURFACE TEMPERATURE, NOT AN AMBIENT/AIR TEMPERATURE, AND CANNOT BE TAKEN BY ANY TYPE OF STICK-ON THERMOMETER!!!! IT MUST BE TAKEN BY EITHER A DIGITAL THERMOMETER THAT HAS A PROBE THAT YOU CAN SIT DIRECTLY ON THE BASKING SPOT/PLATFORM, OR BY AN INFRARED TEMPERATURE GUN THAT YOU CAN POINT DIRECTLY AT THE SURFACE OF THE BASKING SPOT/PLATFORM...
****So if I'm correct and that "All Living Things" LCD Strip Thermometer does not have a Probe on a wire that you are placing directly on his Basking Spot/Platform to get that Surface Temperature of 105 degrees F, and it's simply a thermometer that is stuck on the glass within the Hot Side of his tank, then that 105 degrees F is not actually his Basking Spot Surface Temperature that should be between 105-110 degrees F, but rather the Hot Side Ambient (air) Temperature that should be only between 88-93 degrees F...
How large is your dragon's tank?
And another question, the Reptisun 10.0
UVB light that you purchased, is it the long, fluorescent tube version of this
UVB light (at least 18" long and inside a long tube fixture), or is it either the compact or coil version of this
UVB light (like a regular light bulb and screws into a regular light bulb socket)?
