Exo Terra Glow Light – Medium 21cm

The Exo Terra Glow Light – Medium 21cm is a clamp lamp that lets you put heat or light exactly where your terrarium needs it. It has a metal reflector, a heat-resistant porcelain socket and a spring-loaded swivel clamp, plus an on/off switch on an extra-long power cord. The inside of the reflector carries a luminous coating that stores light during the day and glows softly after the lamp goes off. This moonlight effect lets day-active reptiles settle into their hides calmly, helps nocturnal species see, and lets you check on animals at night.

Wattage limits and placement

Match the bulb to the size you choose: Exo Terra rates the 14cm Small for bulbs up to 100W, the 21cm Medium up to 150W and the 25cm Large up to 200W, so the larger reflectors suit stronger heat lamps and wider basking areas. Exo Terra advises against using Glow Light models with its own glass terrariums; for those it recommends the Light Dome fitted with a Light Bracket instead. Position the lamp so your animal cannot touch the bulb or reflector, and expect the luminous coating to keep glowing faintly for a while after you switch off.

Good to know

Switch off and let the reflector cool before changing a bulb, and always use a bulb within the lamp’s rated wattage.
