Designed for reliable performance, these T8 10W bulbs deliver concentrated energy through advanced narrow-spectrum technology for optimal results. All New 365nm Narrow-Spectrum Technology：This New FSL BL T8 F10W 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 efficiency. 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.
