i have a 2x2x4 foot cage, and in the very back i have a 18 inch retisun 5.0 and in the very front i have one. Is that too much? its just dark in his cage, its in a room with little to no sunlight
with your basking light it is dark? t8/t12 5.0 bulbs arent high output as far as lumens are concerned. usually your basking light makes up for that. i also use a dual fixture 5.0 reptiglo/6800k plant bulb. those two combined put out pretty good light. once the basking bulb (75 watt house bulb) is turned on the cage lights up like a nice sunny day..from the outside windows im sure my neighbors think im growing some greenary.
