I can't help since I don't know what other options you could have... Maybe a big rubbermaid tote? It should be ok for a few days to a week.
However, please, please don't use that bulb. I bought it when I first brought my boy home, and the change in him was almost instant- he stopped eating, stopped moving, and just sat under his log with his eyes clamped closed all the time. Never been so freaked out in my life, I was convinced I'd killed him. I only had it on there for 3 days, and it took him almost a week to start acting normal again. Zilla is supposed to be fixing the issue, but I don't know if they actually have yet, and I know for a fact pet stores kept selling them even though they were recalled, so it's impossible to say if you have one that will hurt him or just a sub-par bulb.
