Frequently Asked Questions about Hermit Crab Heat Lamps & Lights

What is the difference between heat bulbs and heat-only emitters for hermit crab enclosures?

Heat bulbs give off light and warmth, which can be useful during the day but should be turned off at night to keep a proper dark cycle. Heat-only emitters make warmth without light, so they can run overnight to help keep temperatures steady when lights are off. With either option, use the correct fixture and wattage so you warm the habitat evenly instead of creating a single overly hot spot.

Do hermit crab heaters need a thermostat, and how should I monitor temperatures?

Pairing any heat source with a thermostat helps prevent overheating and keeps the enclosure in a narrow, stable range. Use at least one in-tank thermometer to check actual readings, and adjust bulb wattage, distance, or coverage if you notice hot or cool zones. This setup gives the steady, even warmth that supports natural behaviors and daily well-being.
