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. T1248/830/LEDG2/2/RP 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. Enjoy lower maintenance costs compared to traditional fluorescent linear lights.
