Reptile Heat Lamp Hagen Exo Terra PT2189, 25 W, UV light, 1 pc

Hagen Exo Terra PT2189 is a 25 W reptile heat lamp with integrated UV output supplied as a single bulb. It provides localized radiant heat and ultraviolet radiation intended to support thermoregulation and natural behaviour of reptiles and amphibians in terrarium environments. The lamp is designed to create a defined basking spot while delivering UVB radiation at levels suitable for species that require higher UV exposure, and it can be used where additional UV penetration is needed through screen covers.

Advantages

The Exo Terra PT2189 combines heat and UV in one lamp, allowing a single fixture to deliver both a warm basking area and supplementary UVB. Its UV output is intended to support vitamin D3 synthesis and calcium metabolism for reptiles that require higher UV levels. The lamp’s light and heat output make it suitable for creating focused basking zones without occupying multiple sockets or fixtures.

Suitable for

• Desert-dwelling reptiles that require higher UVB exposure
• Terrariums where a defined basking spot is needed
• Enclosures with denser screen covers that reduce UVB penetration
• Species and setups needing supplementary UVB alongside heat

Key specifications

• Power: 25 W
• Type: Reptile heat lamp with UV (single bulb)
• Function: Provides localized radiant heat and UVB radiation
• Effective use: Designed to create defined basking spots and supplementary UV exposure in enclosures

How to use

Install the Hagen Exo Terra PT2189 in a suitable lamp holder positioned to create a clear basking area at an appropriate distance from the animal, taking into account species-specific temperature and UVB requirements. Use an appropriate fixture or reflector rated for the bulb type and ensure secure mounting to avoid contact with animals or flammable materials. Monitor enclosure temperatures with a reliable thermometer and adjust bulb height or wattage as needed to maintain recommended basking temperatures. Replace the bulb according to manufacturer guidance or when UV output diminishes, even if visible light remains.

Usage recommendations

Place the lamp so that animals can choose between basking and shaded areas; combine with ambient lighting when visual light output is required. In enclosures with dense screen covers, position the bulb closer or use complementary lighting to ensure adequate UVB levels. Regularly check temperatures and consider periodic bulb replacement to maintain effective UVB and heat output.
