The item has a light dome and suspension. It is easily adjustable and prolongs the life of the bulbs, as they do not need to be moved after installation, and ventilation is increased. It hangs securely on most lighting fixtures and helps prevent accidental overturning as well as damage to the terrarium. The Exo Terra light bracket is designed to securely attach the Exo Terra Light Dome or other types of domes (bodies) above any Exo Terra Natural Terrarium or other glass terrarium. It serves to regulate the heat and light according to the necessary conditions of the terrarium by moving the rubber washers.
