Feit Electric's 13-Watt Equivalent Direct Replacement (Type A) Non-Dimmable Linear LED Tubes replace F13T5 or T5 fluorescent and LED tubes. They work with most existing electronic ballasts for quick and easy installation， with no rewiring necessary. Each Linear LED light produces 1100 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. T521/830/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 $1.45 per year.
