Best option for you would probably be a ceramic heat emitter on a thermostat, and you cannuse the same light fixtures IF they have thenceramic socket. Having them on a thermostat will keep the cage temps stable even when the room temps vary.
Thanks, will probably go that route. How do I check if they have the ceramic socket? [Should i say somewheres?]
