Product Information

The ET Glow Light/Reflector Medium 21cm (PT2054) is a versatile, clamp-mounted lighting fixture designed for reptile and amphibian keepers who need reliable, repositionable heat and light placement on any terrarium. What sets it apart is the luminous reflective coating inside the dome — a practical feature that makes this a genuine day-and-night fixture without the need for a separate night lamp in most setups.

Luminous Reflective Interior

The inside of the reflector is finished with a highly reflective luminous coating that absorbs light energy during the day and slowly releases it after the lamp is switched off. This soft, moon-like glow allows nocturnal species to navigate naturally and gives diurnal reptiles and amphibians a stress-free transition into their night hides. It also lets keepers check on animals after dark without switching on full lighting, which can cause stress and disorientation.

Construction and Fitting

  • Sturdy metal reflector dome, 21cm diameter
  • Heat-resistant ceramic (porcelain) socket for safe, long-term use
  • Spring-loaded swivel clamp for secure, adjustable positioning on terrarium rims or edges
  • On/off switch mounted on an extra-long power cord for convenient control
  • Maximum wattage: 200W

Bulb Compatibility

The standard screw fitting accepts a wide range of bulb types, including compact fluorescent and incandescent lamps. It is compatible with basking spots, neodymium daylight bulbs, halogen lamps, compact UVB bulbs (2.0, 5.0, and 10.0 variants), infrared heat bulbs, and high-output bulbs up to 125W solar-type lamps, among others. If used solely for heating at night, an additional night bulb can be added — otherwise the luminous coating removes that requirement entirely.

Energy Efficiency

The reflective coating redirects light rays that would otherwise be lost through the dome walls, making better use of each bulb's output compared to standard uncoated fixtures. The stored glow requires no additional power to maintain after the lamp is off, adding a passive benefit with no running cost.

A well-built, practical fixture for any vivarium setup — the ET Glow Light/Reflector Medium 21cm handles daytime basking or lighting duty and transitions seamlessly into a night-safe environment, giving keepers one less thing to manage after lights out.
