What does your enclosure look like?? What kind of lights do you have in the enclosure?

my beardie's tank is approximately 4 ft i'm using a 30 inch 10.0 uv tube, the basking temp using a 100 watt bulb is approx 33 degrees with a cool end of 26 degrees. Lights are on for 10 hours a day. At the moment i am currently using a night light which comes on every hour for 15 minutes during the night. My beardie does not appear to be disturbed by it, it's soo cold at the moment his temps at night are dropping as low as 14 degrees. Thanks in advance.
