So I bought a 55 gal tank and the t-rex uvb/heat bulb.... the basking area is too hot... the directions say not to use the bulb with a thermostat. Has anyone else used this bulb with a thermostat? Its a 100 watt focus.... that was the lowest wattage they had available..... since I've been home monitoring the temp I have been turning the light off and on as necessary.... I can't do this when I'm at work.... Suggesstions? BY THE WAY, you guys are great!
A thermostat on a UVB bulb will not work. It is only useable on non-UVB lights and light-less heat sources. How close do you have the UVB/heat bulb? You can have it as far away as 18" and still get the minimum required UVB from this bulb.
On the box it should say something like "no closer than 12". This is actually good advice. Any closer and the temps get very high...as you found out... . For the type of bulb you are using the distance can be anywhere between 12" - 18" for proper UVB emissions. If you still have high temps at 18" then you have a problem. Hopefully the moving it will help.
