Heat Bulb Hagen Exo Terra Night Heat 25W for Reptile Enclosures

Hagen Exo Terra Night Heat 25W is a heat bulb created for reptile and amphibian enclosures that delivers focused radiant warmth without producing visible light. Designed to provide supplemental night-time heating, this 25-watt lamp helps maintain stable ambient temperatures in terrariums, shelters, and breeding areas while allowing animals to retain natural dark-night behavior. The bulb is intended for use where unseen heat is required to support thermoregulation and comfort during cooler periods.

Advantages

The Exo Terra Night Heat 25W emits infrared heat that warms surfaces and animals directly rather than brightening the enclosure, minimizing disturbance to nocturnal activity. Its low wattage provides gentle, localized heating suitable for small to medium enclosures and for use in combination with daytime heat sources. The compact design fits standard reptile lamp fixtures and allows controlled placement to create warm microhabitats without altering visible light cycles.

Suitable for

• Night-time heating in small to medium terrariums and vivaria
• Maintaining ambient temperature in shelters and hide boxes
• Supporting thermoregulation for reptiles and amphibians during cooler nights
• Breeding setups that require uninterrupted dark periods with supplemental warmth

Key specifications

• Power: 25 watts for low-output night heating
• Emission: Infrared radiant heat without visible light
• Intended use: Indoor reptile and amphibian enclosures
• Form factor: Compact bulb compatible with standard lamp holders used in terrariums
• Heat distribution: Targeted radiant warmth suitable for creating warm microzones

How to use

Install the Hagen Exo Terra Night Heat 25W in a suitable ceramic or heat-resistant lamp fixture positioned above or adjacent to the desired microhabitat. Ensure the bulb is mounted at a safe distance from substrate, décor, and animals to prevent contact burns; adjust height to achieve target surface temperatures. Use a thermostat, dimmer-compatible controller or timer where appropriate to maintain stable night-time temperatures and to avoid overheating. Regularly inspect the fixture, bulb and enclosure for secure mounting and proper ventilation.

Usage recommendations

Monitor enclosure temperatures with an accurate thermometer or surface probe to set appropriate placement and control settings. Combine this night heat bulb with daytime basking lamps or heat mats as needed for a full thermal gradient; do not use the bulb in wet or unprotected fixtures and avoid direct contact with water or flammable materials.
