• 【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.

【Product Description】 FSL BL T8F10W 365nm Fly Killer Replacement Bulbs – 2-Pack. [Upgrade your 20W fly killer or bug zapper with the 2026 upgraded version of the FSL BL T8F10W replacement bulbs. Designed for reliable performance, these T8 10W bulbs deliver concentrated UV energy through advanced narrow-spectrum technology to effectively attract and eliminate flying insects]. [All New 365nm Narrow-Spectrum Technology] [This new FSL BL T8F10W model represents a significant advancement over previous generations. Traditional broad-spectrum bulbs operate with lower energy density and less focused output. In contrast, our 2026 version features narrow-spectrum technology with a peak wavelength of 365nm, concentrating energy precisely for significantly improved insect attraction. The 365nm wavelength is scientifically proven to be most effective for attracting houseflies, mosquitoes, moths and other flying pests]. [Enhanced User Comfort]. [We identified that broad-spectrum design could lead to blue light leakage around 410nm, causing potential eye discomfort. In response, we optimized the inner coating of our bulbs to effectively block blue light above 400nm. This thoughtful improvement ensures a more comfortable experience during use]. [Specifications].
