Hello! I have a self made beardie enclosure for Gilberto, who is 5 months old. Dimensions are 50x17x23. Currently I have a tube light (exoterra) 10.0 and a 75w flood light as basking spot. Temperatures range from 85F to 115F directly below the basking spot, dropping to 70’s at night. However, winter should make temperatures drop even more. I bought a 100w CHE but I’m not sure where exactly to install it? Same side of the basking spot or the opposite side will be ok? (Because it’s a self made enclosure it might be a bit difficult to install them both on the same side but I can try). Also, is the wattage of the CHE too high? Should I get a lower wattage bulb or 100 will be ok? Thanks so much!!
