Agreed. Some houses don't have central air. My house doesn't so we use window ac units. This morning temp outside was 32 and inside was 65. I came home on lunch and temp outside is now 75 and inside is 87 with the sun beating on my house. If I was using a dimmer my temps would of been higher than they should. It has happened before. You just have to prepare for these changes. Ok I'm done hijacking this thread. I misused my words and I'm sorry and I corrected it.
To the OP, my mistake and JoshSloane and my conversation gives you a little insight on dimmers. You need to monitor them more closely than thermostats. You still need to monitor thermostats but they will constantly adjust to give you the right temp. I think one thing me and JoshSloane can agree on is if you have the funds buy a quality thermostat. Like a Herpstat or ve-200d. There is cheaper on/off models like ve-100 and even cheaper is hydrofarm which others members have said are good. I personally would not use an on/off style for a lamp heat source bc the light will constantly flicker on and off but for a uth it would be fine. If those thermostats are out of reach for you then yes a lamp dimmer will work.
Also once you get your enclosure set up post some pics and ask for advice. It worked well for me!
