Light Dome Hanging Bracket – Light Dome or Wire Light Hanging Bracket – Easily Adjustable – Extends Bulb Life – Suspends Most Light Fixtures Securely – Helps Prevent Accidental Tip-Over – Prevents Terrarium Damage The Exo Terra Light Bracket is designed to suspend the Exo Terra Light Dome (# PT2055, PT2057) or other types of dome or wire light fixtures above any Exo Terra natural terrarium or other glass terrarium securely. The Exo Terra Light Bracket easily adjusts to fit most types of light fixtures or can be used to regulate heat/light to the required terrarium conditions by moving the rubber washers. Since the bulbs do not need to be moved after installation—with increased ventilation—the life of the bulbs (heat lamps, Solar Glo, etc.) is greatly improved.
