Feit Electric's 8-watt Equivalent Direct Replacement (Type A) Non-Dimmable Linear LED Tubes replace F8T5 or T5 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 450 lumens, while using less energy than fluorescents. 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. T512/865/LED 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. Switch to Type A LED linear lights for your space and get up to 35,000 hours of superior light. That's 31.9 years based on 3 hours of daily use.
