This may be an ignorant question but is there a large difference between using a dimmer versus using a thermostat for a CHE? What about a rheostat? I am planning to utilize a 100w bulb with a lamp stand as the main heat source for my enclosure but I am concerned that a dimmer won't be as accurate nor as safe as a thermostat. What are your experiences and do you have possible images you could share of your set up to help educate me better? Thank you!
