Alright so im looking at adding another bulb or 2 to my iguanas cage, I dont think its staying warm enough. His cage is 7' tall 4' wide and 4' front to back. Right now i have a 125w solar glo mvb and 1 regular 75w basking bulb. then i have 1 cerami heat emmiter and 1 of the heat projector bulbs from reptile uv both of these bulbs come on at night. im thinking of getting like a 100 watt to replace the 75w basking bulb or adding another basking bulb. Should i also add one of the repti sun uv bulbs or would that be to much uv with the solar glo?
