Exo Terra Reptile UVB300 T5 VHO Bulb 24W 22", Ultra‑High UVB Output Bulb for Midday Sun Reptiles, Very High Output T5 Lighting for Vitamin D3 & Calcium Support, Ideal for Tall Terrariums

• Exo Terra’s Reptile UVB300 T5 VHO bulb is crafted in Germany for exceptional quality and delivers strong, consistent UVA/UVB performance for 12+ months, ideal for reptiles requiring intense midday sunlight exposure.
• Provides powerful UVA/UVB and a balanced visible light spectrum tailored for reptiles from the Euphotic and Heliophotic Zones that naturally bask under peak sunlight conditions.
• High UVB output promotes efficient Vitamin D3 synthesis, improving calcium absorption and helping prevent Metabolic Bone Disease in reptiles that thrive under strong solar intensity.
• Outperforms T8 and energy‑saving bulbs with deeper UVB reach, making it ideal for taller enclosures or setups with dense mesh lids that typically block UV radiation.
• Works with UV Index guidelines to create proper basking zones and shaded areas; longer bulb sizes can span multiple terrariums and pair effectively with infrared‑A sources like Exo Terra Halogen or Intense Basking Spots for complete sunlight simulation.

Product Description Exo Terra®'s exceptional T5 lamps are crafted in Germany to the highest quality standard, ensuring a prolonged UV output of 12+ months for lasting performance. With its intense output of UVA and UVB rays – combined with a well-balanced visible light spectrum – the Exo Terra® Reptile UVB300 T5 Very High Output Bulb is specifically designed to meet the needs of reptiles basking in open or midday sun in the Euphotic or Heliophotic Zones. The intensity of the emissions varies depending on the distance from the basking area. Higher levels of UV are vital for the physiological wellbeing of these animals, which thrive under intense sunlight. They actively interact with their environment when the sun is high or even at its peak – showcasing an exemplary adaptation to solar intensity by optimising body temperature and UVB intake during basking behaviour. The Exo Terra® Reptile UVB300 VHO T5 Bulb helps promote healthy Vitamin D3 synthesis, which in turn facilitates improved calcium absorption – safeguarding against Metabolic Bone Disease. Its UVA and UVB emissions surpass those of traditional T8 bulbs and energy-efficient alternatives, while enhanced UVB penetration extends its suitability for use in taller terrariums or those equipped with denser screens.For optimal results and prolonged lifespan of the bulb, we recommend using it in conjunction with the Exo Terra® T5 Terrarium Top High-Performance Reptile UVB Fixture.Long-lasting UVB output (12+ months).The longer sizes can be placed across multiple terrariums.Keepers can use the UV Index reference values to ensure that animals are exposed to an appropriate level of UV when basking. Creating a gradient – from highest safe UV index at the basking area to lowest UV index in cooler areas – means they can completely self-regulate alongside their thermoregulatory behaviours. They should not be allowed to expose themselves to more than a safe maximum and should have the freedom to escape all light completely with areas of zero UV and Infrared. This can be achieved by strategically adding plants, hides, and decorative items to create shaded zones. To support the efficient conversion of vitamin D3 and enhance various metabolic and hormonal processes, it is beneficial to ensure that UV light exposure is complemented by an ample supply of infrared-A (NIR) radiation. The most effective sources can be found in Tungsten Halogen or standard Incandescent spot bulbs, such as the Exo Terra Intense Basking Spot or Halogen Basking Spot. This combination promotes optimal body temperature regulation and overall well-being.Pet care lamp for use with Reptiles, Amphibians and Invertebrates only.
