Frequently bought together:


The Dimmer B1 HT Thermostat allows precise control of any heat source up to 600w by using advanced microprocessor technology.

The HT version differs to the standard Dimmer B1 by controlling a higher temperature range more suitable for species such as uromastyx and bearded dragons.

The B1 HT is a dimming thermostat that gradually varies the power supplied to the heat source for a smooth change in temperature inside the vivarium.

A recessed temperature control adjuster is used to prevent accidental temperature changes if the unit were to be knocked which would be easily done if the dial protruded from the casing. A yellow LED provides real time feedback as to how much power is being supplied to the heater.

Long cable lengths ensure the unit can be fitted easily into most vivarium setups.
An external fuse protects the thermostats from faults generated from the heater.


Max power output:          600w

    Item arrived broken could not get a replacement until it was sent back i had a family meme her with covid so was having to self isolate myself. I didn’t have the funds to buy another one. My back up also packed in so my dragon was without heat for 4 days.
