Feit Electric’s 10-watt Direct Replacement (Type A) Non-Dimmable Linear LED Tubes replace F17T8 or T8 and F20T12 or T12 fluorescent and LED tubes. They work with most existing electronic ballasts for quick and easy plug-and-play installation, with no rewiring necessary. Each Linear LED light produces 800 lumens, emitting the same light output level as traditional fluorescent linear lights while using 50% less energy. These bluish-white 6500K Daylight Deluxe White lights allow you to see objects in finer detail and create a vibrant mood for both residential and commercial spaces. Use them in closets to see every wardrobe detail. They are ideal for retail stores, gyms, convenience stores, and hospitals, and high-traffic locations where customers and employees need to feel alert or focused. T24/865/LEDG2 lights turn on instantly, offering flicker-free full illumination with no warmup time compared to fluorescent tubes. They are mercury-free, with a shatter-resistant coating for safe and easy disposal. Each high-quality bulb offers accurate color rendering, for more vibrant, true-to-life colors. Lower heat emission extends the life of the tube and ends do not turn black or burn with age. The estimated energy cost is only $1.20 per year. Switch to Type A LED linear lights for your space and get up to 50,000 hours of superior light. That's 45.7 years based on 3 hours of daily use.
