73 is definitely too cold. You don't want to go below 75 but 80 is ideal for cool ambient. Definitely get a Che, which won't be too hot if you have it regulated by a thermostat.
OK! Thank you. Could I just use a dimmer? I bought at Lowe's, and I have heard other people saying that they are good because you don't need to spend that much on ine of those fancy thermostats.
