Reptile Heat Lamp Hagen Exo Terra PT2120 15W 1500K, 1 pc

Hagen Exo Terra PT2120 15W 1500K heat lamp is a low-wattage nocturnal lamp designed for terrariums and reptile enclosures. The lamp emits a bluish moonlight-like glow through blue glass, allowing owners to observe nocturnal activity without significantly affecting the animals' natural day–night cycle. Its modest heat output provides just enough radiant warmth to maintain tropical night temperatures and support thermoregulation while preserving normal nighttime temperature drops.

Advantages

The Hagen Exo Terra moonlight lamp combines visible blue-tinted illumination with gentle radiant heat in a single compact bulb. Its low power consumption minimises disturbance to sensitive species while still supporting behaviours such as nocturnal activity and breeding. The lamp is compatible with common terrarium fixtures, enabling simple integration into existing setups and allowing coordinated use with daytime heat lamps or full-spectrum lighting to establish a 24-hour thermal and light cycle.

Suitable for

• Nocturnal reptiles and amphibians that require minimal nighttime light
• Terrariums where night-time observation is needed without disrupting the photoperiod
• Enclosures that need gentle night-time warmth to maintain tropical temperatures
• Setups aiming to stimulate natural behaviours such as breeding through controlled night conditions

Key specifications

• Power: 15 W
• Colour temperature: 1500 K (bluish moonlight appearance due to blue glass)
• Function: provides low radiant heat and visible nocturnal illumination
• Light output: low-intensity, suitable for night viewing without strong photic stimulation
• Recommended use: supplemental night-time heating and observation in terrariums

How to use

Install the lamp in a fixture rated for the bulb type and wattage and position it to create a localized basking or warm area while avoiding direct contact with animals or substrate. Use the lamp during night hours only if the species benefits from minimal illumination; pair with daytime heating and lighting sources to form a full 24-hour cycle when required. Monitor enclosure temperatures with a reliable thermometer to ensure night temperatures remain within the species’ recommended range.

Usage recommendations

Place the lamp so it provides gentle radiant warmth without creating hot spots; avoid enclosing the bulb where heat could build up. Combine with thermostatic control or timed lighting to maintain a consistent photoperiod and temperature gradient suitable for the species housed.
