Reptiles are ectothermic, depending entirely on external heat sources for body temperature regulation. Providing the correct heating method and temperature gradient is fundamental to reptile health.

Basking Bulbs

Halogen flood bulbs provide focused basking spots with both heat and visible light. They are the most natural heating option, as they simulate sunlight warming. Wattage determines heat output; experiment to achieve your target basking temperature.

Ceramic Heat Emitters

CHEs produce heat without light, making them ideal for nighttime heating when light would disrupt sleep cycles. They screw into standard dome fixtures and last significantly longer than basking bulbs. They create hot air rather than infrared radiation.

Deep Heat Projectors

A newer technology, DHPs emit infrared-A and infrared-B radiation similar to sunlight, providing a more natural heat source than ceramic emitters. They heat objects and surfaces rather than just air, mimicking basking in sunlight. They also produce no visible light.

Under-Tank Heaters

Heat mats placed under one end of the enclosure provide gentle belly heat preferred by some species, particularly nocturnal geckos and snakes. They must always be used with a thermostat to prevent dangerous overheating. Never place heat mats under thick substrate.

Thermostat Necessity

Every heat source must be controlled by a thermostat. Unregulated heating equipment can overheat enclosures to lethal temperatures. Proportional thermostats provide the smoothest temperature control. Dimming thermostats work with bulbs; on-off thermostats work with CHEs.

Creating Temperature Gradients

Place heating on one end to create a warm basking zone and a cooler retreat zone. This gradient allows reptiles to thermoregulate by moving between zones. Monitor temperatures at both ends with digital thermometers. The cool end should still meet minimum species requirements.
