Ackie enclosure help!!!!

[jbreadyrltw]

hey guys, so im getting a pair of red ackies from Brandon at rare earth on the 25th of November. I am picking up my custom cage one of my buddies built for me who runs a monitor rescue.. the cage is (LxWxH) 3x2x4. Brandon told me cage size was plenty good as ackies love to climb if given the option. Now here is my question. I have 3 in cage mounted ceramic light fixtures at the top of the cage.1 for heat/basking (which I have a shelf built for to make a nice bask area), uvb(I know most argue its not needed but it cant hurt), and a night bulb to keep ambient night temps around 80. Brandon said he was concerned with the bulb at the top of the cage not being able to keep the substrate at 85 degrees which I know is essential for breeding and egg laying. He recommended getting rid of the top bulb for heat and placing a side mounted bulb about 9 inches off the soil(which will be 1 foot deep) what are your thoughts? I like having the heat lamp up high as I stated I have a nice built in basking shelf up there and I have some cork log and 3 feet long sandblasted grapevine that I was going to put up to the basking shelf. but I also want the soil at 85 degrees for breeding purposes. any thoughts appreciated!
