Welcome to The Bio Dude!
With the Exo Terra Dimming & Pulse Proportional Thermostat 600W with Day/Night function you can create a well-controlled heating system that allows you to maintain the required temperature conditions similar to those found in a desert or tropical environment. The dimming thermostat will also help to prevent overheating and undercooling during hot summer days or cold winter nights. Both the daytime and nighttime temperatures can be set separately to guarantee safe daytime-nighttime temperature fluctuations for your reptiles.
