Best way to heat a 432 vision cage

I'm wondering what's the best way to heat this cage with? I'm thinking a radiant heat panel but I'm not sure what size will do. I do not think a heat bulb would be enough and I'm scared to use a ceramic heater instead of a bulb on that cage. Any suggestions would be greatly appreciated.

I think a 50-80 watt radiant heat panel would do the job.

Don't those cages have some hole cut outs in the back or top for maybe 8" CHE's?

there is a 8 inch hole for a 75 watt max heat bulb and I was thinking of using a CHE but that alone will not be enough for a cage that big in a cold room (63 deg in the winter time)

I heat all my Visions with Flexwatt heat tape.

Yeah, but flex watt won't heat the ambients if the room ambient is 63F in the winter.

I use RHP's for my boas and they are really great and do bump ambient temps. I would maybe give Rich a call (or email) at Reptile Basics and ask him what size you would need given the cage and the room temp in the winter.
