Thank you so much for the advice! Not gonna stick with the coil and will be looking into a new bulb ASAPOk if you want to stay w/ the coil I dont recommend it but if you do please get the Reptisun 26 watt its a better bulb than your Exo Terra I am not a fan of coils please get the 26 watt unobstructed w/a distance of 6-8 inches directly above the basking decor - if you have the coil on the screen hes getting little to NO UVB hence the cause of not eating --- I can recommend some good UVB fixtures w/ bulbs if you like but your dragon will continue to decline in health w/the bulb your using now ---
The Reptisun 26w version of the UVB150 is similar in output to a T8 tube when using a reflector. The beam isn't as wide (depending on the length of the tube) but the output strength is very similar. If it was sitting about 6-8'' above the main basking area then it was likely providing adequate UVB. It's the lower wattage (13w) versions that cause concern since they aren't strong enough to provide adequate UVB at a safe distance.
