Exo Terra TerraSky UVB LED Spot Bulb 3W

The Exo Terra TerraSky UVB LED Spot 3W ES is a compact, energy-efficient UV light source designed for terrariums where precise UV delivery matters. Its focused beam drives UVB and UVA deeper into the enclosure than a diffuse source would, letting keepers create a defined high-UV basking zone while animals self-regulate their own exposure by moving in and out of the beam.

UVI Output at Distance

This spot has been measured across three distance ranges, giving keepers a clear picture of where to position it for each species' UV requirements:

• 0–15 cm: 9 UVI
• 15–25 cm: 3–5 UVI
• 25–50 cm: 1–2 UVI

Broad-Spectrum UV and Visible Light

The lamp combines UVB, UVA, and 6500K LEDs in a single unit, producing a wide spectrum that covers both biological and visual needs. UVB drives vitamin D3 photosynthesis, supporting calcium absorption and reducing the risk of metabolic bone disease. UVA supports appetite, activity levels, and reproductive behaviour, while also helping to lower stress in captive animals.

Long Service Life

The LED chips used in the TerraSky UVB LED Spot 3W ES are rated for up to 20,000 hours of use — equivalent to four or more years of regular operation. That longevity reduces the frequency of bulb changes and helps maintain a consistent UV output over time.

Compact Format and Compatibility

The compact form factor makes this spot suitable for use on smaller terrariums where a larger UV fixture would be impractical. It can be paired with a Daytime Basking Spot or an Intense Basking Spot to meet the specific temperature and UV combination required by your animals.

For keepers who want targeted, measurable UV delivery in a long-lasting LED format, the Exo Terra TerraSky UVB LED Spot 3W ES is a straightforward, well-specified choice for a wide range of reptile and exotic species setups.
