The Exo Terra Ceramic Heat Emitter 60W (110 V) provides infrared radiant heat without producing light, similar to the 150W version but with lower heat output for smaller enclosures. It screws into a standard ceramic-socket fixture and is ideal for maintaining nighttime temperatures or adding round-the-clock warmth. The 60W ceramic heater efficiently raises ambient terrarium temps and supports healthy metabolism and digestion, all while keeping the enclosure dark at night for a natural day/night cycle.
