Exo Terra Light Dome Fixture 18cm | PT2057 Vivarium Lamp Dome

The ET Light Dome Fixture 18cm (PT2057) is a compact, versatile lamp holder designed to sit directly on the mesh top of Exo Terra terrariums. Its small footprint makes it a practical choice for keepers who need reliable, focused lighting without cluttering the top of their setup. Suitable for a range of incandescent and compact fluorescent bulbs, it gives you the flexibility to build a lighting system tailored to your animals' requirements.

Polished Aluminium Reflector

The highly polished aluminium reflector is built to direct and amplify output, increasing light, UVB, and UVA delivery by up to 100% compared to an unhoused bulb. This means more of what your reptiles need actually reaches them, rather than being lost to the surroundings.

Ceramic Socket Compatibility

The ceramic socket handles both compact fluorescent and incandescent bulbs safely, accommodating incandescent bulbs up to 75W and compact fluorescent bulbs up to 26W. Note that Solar Glo and Ceramic Heat Emitter bulbs are not compatible with this fixture.

Mounting and Installation

The fixture comes with a switch, clamp, and hanger included, so it can be positioned and secured straight out of the box. The clamp and hanger give you options for mounting directly to the terrarium screen or suspending it depending on your setup.

Building a Lighting System

Multiple fixtures can be combined and paired with different bulb types to create distinct lighting zones — separating UVB provision, visible light, and basking heat across the same enclosure. This makes the ET Light Dome Fixture 18cm a practical building block for more complete vivarium lighting setups.

A straightforward, well-made dome that gives reptile keepers genuine control over their lighting — without compromise on output or compatibility.
