Vivarium Electronics VE-200D Thermostat (Reptile Basics)

This came highly recommended by fellow reptile-keepers. I needed this baby for to regulate the heat on my rack. It's done an excellent job and so happy I invested in this. Don't use crap thermostats for your racks, people!

very good for incandescent bulbs i highly recommend but not so good for ceramic heaters get a pulse proportional for that
