Exo Terra Natural Light Compact Lamp 26W (PT2191) | Full-Spectrum Vivarium Bulb

The ET Natural Light Compact Lamp 26W is a full-spectrum daylight compact fluorescent lamp designed as a general-purpose light source for vivaria and terrariums of all types. With a 6700K colour temperature and an exceptionally high 98 CRI, it produces bright, natural-looking light that accurately renders colours and supports plant growth — making it a solid choice for planted set-ups and for keepers of snakes, amphibians, and nocturnal species whose UV requirements are lower than desert or savannah animals.

Spectrum & Light Quality

At 6700K, this lamp produces a crisp daylight tone that closely mimics natural outdoor light conditions. The 98 CRI (Colour Rendering Index) means colours within the vivarium are rendered with near-perfect accuracy — useful for observing your animals and for supporting photosynthesis in live planted terrariums. The high visual light output makes it effective even in deeper or larger enclosures where lesser compact lamps can fall short.

UVA Output & Animal Behaviour

Though not a dedicated UVB source, this lamp does emit UVA radiation, which plays a documented role in stimulating appetite, activity levels, and natural reproductive behaviour in reptiles and amphibians. Animals that cannot see UVA experience their environment very differently — this lamp helps close that gap, even for species with modest UV demands.

Which Animals Is It Suited To?

• Snakes — a natural fit given lower UV requirements
• Amphibians including frogs, toads, and salamanders
• Nocturnal reptile species where strong UVB is not required
• Planted vivaria where light quality and plant-growth support matter

Pairing With UVB Sources

For species that do require meaningful UVB exposure, this lamp is best used alongside a dedicated UVB compact or tube lamp appropriate to that animal's UV index requirements. It functions as the visible light and UVA component of a broader lighting system, rather than a standalone UV solution. This updated spectrum replaces the former Repti Glo 2.0 range.

For keepers who want accurate colour rendering, genuine UVA stimulation, and strong visual output from a compact fluorescent format, the ET Natural Light Compact Lamp 26W covers a wide range of vivarium set-ups without compromise.
