Terrarium daylight lamp, Hagen Exo Terra PT2377, 25 W, 1 pc

Hagen Exo Terra PT2377 is a 25 W daylight lamp designed for terrarium lighting. This single-unit full-spectrum Natural Light bulb provides daylight-coloured illumination that enhances visible light levels and supports natural-looking diurnal cycles for reptiles, amphibians and planted enclosures. The vivid wavelength distribution improves environmental colour perception and helps create appropriate light conditions in standard terrarium fixtures.

Advantages

The Exo Terra Natural Light emits a balanced daylight spectrum that highlights natural colours and supports visual behaviours in animals with low to moderate UV requirements. Its full-spectrum output contributes to healthier-looking plants and stimulates normal activity, feeding and reproductive behaviour through UVA wavelengths. The bulb is suitable for use as a general-purpose light source in terrariums, and it can be combined with dedicated UVB lamps to reproduce fuller sunlight conditions when required.

Suitable for

• Reptiles with low to moderate UV needs (for example many snakes)
• Amphibians such as frogs, toads and salamanders
• Nocturnal species requiring visible daylight cycles
• Planted terrariums where full-spectrum light supports plant growth

Key specifications

• Power: 25 W
• Light type: full-spectrum daylight (Natural Light)
• Colour appearance: daylight-coloured illumination suitable for natural-looking photoperiods
• Intended use: terrarium lighting for reptiles, amphibians, invertebrates and plants
• Format: single bulb supplied

How to use

Install the Hagen Exo Terra PT2377 in a standard terrarium fixture rated for 25 W. Position the lamp to provide even visible illumination across the enclosure while maintaining appropriate distance from animals and plants according to enclosure design. Use a timed photoperiod (day/night cycle) to mimic natural light rhythms. For species that require UVB, combine this daylight lamp with a suitable UVB product to ensure both visible and ultraviolet components of natural sunlight are available.

Usage recommendations

Use the Exo Terra Natural Light as the main visible light source in terrariums for animals with lower UV needs and for planted setups. When higher UV exposure is required, pair this bulb with an appropriate reptile UVB lamp to achieve correct UVB/UVA balance. Replace bulbs according to manufacturer guidance and inspect fixtures and distances regularly to maintain safe and effective light levels.
