I am setting up a 4x2x2 enclosure for my son's adult Blue Tegu's and thought I'd replace his ceramic heaters with Hologen basking lamps. What wattage should I use? The enclosure has two 4x3 vents on each lower end of each side for circulation. The cage height is 2 ft. I wanted the right bulb size so that I could have them on 24/7 without having the cage get too hot. I have a helix in their to protect them from getting to hot. Thanks in advance. ZACK!
