• 3-in-1 Full Spectrum Sunlight Simulation: Built with 10 visible LED chips, 1 dedicated UVB chip and 11 UVA chips, this uvb light for reptiles delivers a complete light spectrum covering 280-315nm UVB, 315-400nm UVA and visible light. It accurately replicates the natural sunlight of desert habitats: UVB supports natural vitamin D3 synthesis and a natural basking rhythm, UVA supports natural foraging and activity behavior and breeding behaviors, and full-spectrum visible light supports reptiles’ tetrachromatic vision for accurate food and environment recognition.
• High UVB & UVA Output: Measured output data shows this 10W LED UVB bulb delivers far stronger UVA & UVB intensity than ordinary 13W fluorescent alternatives at identical mounting distances. At 4 inches, it reaches 122.71 μW/cm² UVB and 2007.82 μW/cm² UVA--over 3 times the UVB output of standard 13W bulbs (38.48 μW/cm²). Verified performance data at 8", 12" and 16" is also available, ensuring a fully covered basking zone and supports natural vitamin D3 synthesis for your reptiles.
• 24-Hour Auto On/Off Cycle with 3 Timer Modes: The UVB light for bearded dragon supports a fully automatic 24-hour lighting cycle with three selectable durations to match reptiles’ natural circadian rhythm: 4 hours on / 20 hours off, 8 hours on / 16 hours off, and 12 hours on / 12 hours off. The bulb flashes twice to confirm successful timer setup or cancellation, removing the need for daily manual operation. It helps establish a stable day-night cycle for reptiles, supports a steady day-night cycle and simplifies daily feeding and care for keepers.
• 4-Level Adjustable Brightness via Remote Control: Operated easily by the included remote, the reptile uvb light offers 4 dimming levels (25%, 50%, 75%, 100%) to suit diverse husbandry needs. It can be adjusted for juvenile and adult reptiles, different terrarium heights, seasonal daylight changes, and species with varying UVA & UVB requirements, enabling precise, refined UVA & UVB management instead of a one-size-fits-all output. It defaults to 100% brightness on first power-up and retains the last brightness setting after power loss for added convenience.
• Directional-Focused 90° Optical Lens Design: Equipped with a built-in 90° reptile optical lens, this bulb concentrates UVA and UVB energy directly onto the basking area with minimal energy loss, unlike traditional spiral fluorescent bulbs that scatter light and waste most of their UVA & UVB output. It creates a bright, evenly illuminated basking zone with consistent UVA & UVB intensity, and no external reflector or lampshade is required, saving extra accessory costs and improving overall UVA & UVB utilization efficiency.
• Slow, Predictable Light Attenuation & 10,000-Hour Long Lifespan: Unlike traditional fluorescent bulbs that suffer from rapid phosphor aging and exponential UVB decline (where visible light remains but UVA & UVB effectiveness drops sharply), SANSI LED reptile UVB bulb features gradual, stable light attenuation throughout its lifecycle. It offers a 10,000-hour service life--2 to 3 times longer than standard 3,000-6,000 hour fluorescent bulbs--lasting at least 1 year with daily use, significantly reducing long-term replacement costs and avoiding the risk of worn-out UVA & UVB output.
• SANSI Patented Ceramic Technology: Built with SANSI’s core patented ceramic technology, the reptile light offers excellent corrosion resistance and high-temperature tolerance, reducing the risk of electrical leakage and overheating and overheating hazards. It is paired with a hollow heat-dissipation housing for efficient thermal conduction and lower surface temperature, reducing the risk of scalding reptiles in close-range basking. The outer shell is made of flame-retardant PC material, improving electrical insulation and durability and long-term durability for long-term use in high-heat, dry terrarium environments.
• Flexible 3-Way Installation & Species-Specific Desert Reptile Compatibility: This reptile light bulb supports three installation methods to fit different terrarium setups: gooseneck clamp mounting (clamp to tank sides or the top rim), top-base mounting for electronic terrariums, and stand-alone use without extra accessories. It is a UVB 10.0 LED desert-grade bulb, designed for diurnal desert reptiles with high UVA & UVB demand including bearded dragons, sulcata tortoises, leopard tortoises, uromastyx lizards and blue-tongue skinks.
