The point was you need something to regulate the temp. A thermostat is the safest. Yes you can use dimmers, I used them for awhile with my snakes and other reptiles but 2 failed and good thing I was home or it would of cooked them. Then I bought a Herpstat 6. Things happen and its best to be prepared and a quality thermostat is being prepared. You can't always be home watching it.
