What our reptile expert John says about the Arcadia ADCH Reptile Ceramic Lamp Holder and Bracket

The ADCH Reptile Ceramic Lamp Holder is designed as a bulb holder for fitting into a vivarium, specifically with reptiles in mind. It has a ceramic E27 bulb holder (screw in not bayonet) that is fixed on a metal bracket; the metal bracket is flexible so it can be angled to direct the lamp to a specific spot. It is easily fitted into the vivarium by screwing the bracket into position on a wooden surface (screws are not supplied). The ADCH unit can also be fixed to all glass Vivariums and Terrariums with sticky pads (not supplied) or glued in using Araldite. The ADCH unit comes complete with a good length power cable, on/off switch and fitted plug.
