Heat bulb Hagen ExoTerra Night Heat 75W — ceramic infrared heater for terrariums

Hagen ExoTerra Night Heat 75W is a ceramic infrared heat bulb designed specifically for nocturnal heating in reptile and amphibian terrariums. The bulb emits infrared radiant heat without producing visible light, allowing animals to thermoregulate during the night while preserving natural day/night light cycles. Its 75-watt output creates localized warm spots and helps maintain stable ambient temperatures in enclosed habitats.

Advantages

The ceramic infrared design delivers even, penetrating heat that warms surfaces and animals rather than the surrounding air, reducing drafts and hotspots. Because it produces no visible light, the bulb supports nocturnal behaviour and sleep patterns while providing necessary thermal comfort. The robust ceramic construction resists high temperatures and offers a long operating life compared with standard incandescent sources. Installation in compatible fixtures allows targeted heating where reptiles and amphibians most need it.

Suitable for

• Nighttime thermoregulation for reptiles and amphibians
• Creating localized basking or warm retreat zones inside terrariums
• Maintaining stable ambient temperature in medium to large enclosures
• Use in setups where visible light at night would disturb animal behaviour

Key specifications

• Type: ceramic infrared heat bulb (no visible light)
• Power: 75 W
• Function: provides radiant heat for nocturnal use
• Heat delivery: surface-penetrating infrared radiation
• Compatibility: suitable for terrariums and heat-safe lamp fixtures designed for ceramic heaters

How to use

Install the Hagen ExoTerra Night Heat 75W in a heat-resistant socket or fixture positioned to provide a warm zone without direct contact with animals or flammable materials. Place the bulb so it creates a temperature gradient across the enclosure, allowing animals to move between warm and cooler areas. Monitor temperatures with a reliable thermometer or probe and adjust bulb placement or wattage where necessary to achieve species-appropriate night temperatures. Follow the fixture manufacturer’s mounting and safety instructions and allow adequate ventilation around the bulb.

Usage recommendations

Use the ceramic infrared bulb as part of a controlled heating strategy that includes temperature monitoring and consideration of species-specific night-time requirements. Avoid enclosed or unventilated fixture housings and prevent direct contact between animals and the hot ceramic surface. Combine with appropriate daytime lighting and thermostatic controls or timers where needed to maintain consistent thermal cycles.
