Right guys so you have probably seen and heard this question getting asked a million times but I'm having some real problems getting my basking spot to the correct temperature, so ill tell you a little about my setup, I'm using a 3ft viv and my basking setup is a 75w exo terra basking bulb, controlling this is a Habistat thermostat. now I have read tons of posts online about getting the temperatures correct and nothing seems to be able to do it, I have placed the thermostat probe in the cool and set it to 26 degrees. after I let the viv warm up for a few hours I checked the basking spot with a infrared heat gun and its showing between 46-50 degrees in some places. now heres where it gets tricky if I dial the thermostat back at all it pretty much dims to bulb to the point where it isn't giving off any light or heat? if you guys could offer any help that would be great.
