Exo Terra TerraSky UVB LED Terrarium Light 10W

The Exo Terra TerraSky UVB LED Terrarium Light 10W (PT2414) is a high-output, fully controllable terrarium lighting unit designed for reptile and amphibian keepers who want precise control over their vivarium's light environment. With adjustable UVA, UVB, and 6500K white LED channels, it suits everything from tropical bioactive builds to arid desert setups — all from a single fixture.

UVB Output and Species Suitability

The TerraSky UVB LED delivers meaningful UVI across a wide range of distances, making it suitable for species with varying UV requirements. UVI readings at measured distances are as follows:

• 0–10cm: 10+ UVI (caution — too close for direct exposure)
• 10–20cm: 8–10 UVI
• 20–40cm: 3–5 UVI
• 40–80cm: 1–2 UVI
• 80–90cm: 0–1 UVI

UVA, UVB and Animal Wellbeing

UVA output supports natural appetite, activity levels, and reproductive behaviour, while also reducing stress in captive animals. The UVB component delivers a high Vitamin D3 yield index, driving effective D3 photosynthesis to support calcium absorption and reduce the risk of metabolic bone disease. The horizontal orientation and 120-degree beam angle ensure broad, even coverage across the vivarium floor with no dark spots.

Plant Growth and Bioactive Setups

With 51 bright white 6500K LEDs producing strong Photosynthetic Active Radiation (PAR), this unit is well suited to planted terrariums, bioactive vivariums, paludariums, and aquatic turtle enclosures. Orchids, bromeliads, tillandsias, carnivorous plants, mosses, lichen, and aquatic plants all respond well to its high-intensity output and deep light penetration. A dedicated biofluorescence mode activates at night, causing biofluorescent plants, mushrooms, invertebrates, reptiles, and amphibians to glow under the light.

Remote Control and Customisation

The included remote control allows independent adjustment of the 6500K white, UVA, and UVB channels in 10% increments, giving precise control over the spectral output at any time. Three preset sunlight modes and two moonlight modes offer quick intensity adjustments, while three memory slots let you save your own custom configurations. Built-in preset timer options of 8, 12, and 14 hours include sunrise and sunset transitions, making it straightforward to replicate seasonal day-length cycles.

Durability and Build

The LED chips are rated for up to 20,000 hours of use — equivalent to over four years of continuous operation — reducing the frequency of bulb replacements common with traditional UV fluorescent lighting. The housing carries an IP54 waterproof rating, making it suitable for humid vivarium environments including tropical and rainforest setups.

For keepers running planted bioactive enclosures or housing species with specific UV requirements, the Exo Terra TerraSky UVB LED Terrarium Light 10W brings meaningful control and long-term reliability into a single, well-engineered unit.
