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 warm 3000K Bright White lights create a welcoming feeling for both residential and commercial spaces. Use them in bedrooms, living rooms, restaurants, hotel lobbies, or environments you want to feel comfortable and relaxed. T512/830/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. The estimated energy cost is only $0.72 per year. 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.
