I have only used very low-wattage CHEs in the past--and not since Beasley's baby enclosure many years ago. I am experimenting with a 160 watt CHE in Beasley's 4x6 open indoor enclosure, and man is it hot. I raised the lamp it's in way up and have gotten it to be 90F in that area, which is OK, but I know many of you use thermostats on CHEs. Can someone tell me more about using them and what, exactly, to get? How do they work? With a lead into the the enclosure to determine the temp? Thanks!
