I have a 100W CHE on the warm side right now.
Should I use a dimmer even though its on the warm side?
So far it does not seem to be emitting as much heat as the day bulb did, but it is also night so I need to keep that in mind (cooler air temp).
I'll be measuring the temps again tomorrow during the day to get a more accurate reading.

Right now, at 10:44pm EST, I'm reading as follows;
HOT ~ 83 degrees
COLD ~ 77 degrees

The timer on the CHE will kick off in about 15 minutes which will cool it a little more than this.
