This sounds similar to my set-up (although I will be switching to plastic soon) The temps sound good if you can maintain them, I was unable to with the black light, and had to switch to a 75W infra-red. I have the lamp on a dimmer because I have to tweak it from time to time. I usually shoot for 82 degrees on the cool side. Keep an eye on your humidity, as any kind of lamp seems to lower it.
