【Wide Compatibility】FSL BL T8F10W replacement bulbs are designed for broad compatibility—they work with both old magnetic ballasts and new electronic ballasts in 20W fly killers and bug zappers, and fit most major brands including Asp‑ectek, Li‑Ba, Micn‑aron, and many others. 【Packaging】2‑pack. Bulb dimensions: 13.5 x 1 x 1 inches (L x W x H); length excluding pins is 13 inches. 【Next‑Generation 365nm Narrow‑Spectrum Technology】Unlike older bulbs that use a broad spectrum with low energy density and unwanted blue‑light leakage, this new bulb features narrow‑spectrum technology with a peak wavelength of 365nm—the optimal wavelength for attracting flies, mosquitoes, moths and other flying insects. The concentrated energy delivers significantly better attraction efficiency, and zero blue‑light leakage makes it much more comfortable for your eyes. 【Long-Lasting & Low Light Decay】Rated 8,000 hours with stable brightness over time; low light decay ensures consistent UV output for continuous pest control. 【Our Guarantee to You】Each bulb is individually protected with extra care to ensure it arrives in perfect condition—saving you the hassle of returns. However, if any damage does occur during transit, simply reach out to us and we'll send a replacement right away, no questions asked., Weight: 0.110231131 pounds, Manufacturer: AIUTEY
