✔Easy Ballast Bypass Installation - Ghiuop led light tubes must be installed using the ballast bypass method. Just remove the ballast from your fixtures and then directly wire your new T8 tubes. Fluorescent replacement (T8, T10, T12) will save you both time and money as ballasts inevitably fail over time and will require replacement. Ballasts also consume electrical power and by bypassing them you will save even more on your energy bill ✔High Brightness & Energy Efficiency - These 4ft led light bulbs use only 20W to emit 2600 lumens (equivalent to 40W in fluorescent tubes), making them extra bright and energy efficient. Featuring single row of LED chips, they provide over 2600 lumens (>130lm/w) of bright and energy-saving illumination. No annoying flicker and distracting buzz. Energy efficient and environmental friendly. ✔Premium Quality & Long Lifespan - Our led t8 tube uses high quality LEDs which are more energy saving and environmental protection (no UV, IR, or mercury). Better quality, safety, reliability and have longer lifetime up to 50,000 hours than halogen/incandescent/fluorescent bulbs. Equipped with a high-strength aluminum housing, Ghiuop led light tubes are shatter-resistant and offer efficient heat dissipation for extended durability. ✔Fluorescent Tube Replacement & Versatile Application - T8 4ft LED tubes are perfect for replacing T8, T10, and T12 fluorescent bulbs, and are compatible with existing T8, T10, and T12 fixtures, offering a convenient and efficient upgrade. Ideal for various spaces such as garages, offices, shops, basements, and more. Experience a brighter and Higher transmittance compared to a milk white cover. ✔HASSLE FREE WARRANTY - Ghiuop offers quality tube lighting at affordable prices and worry-free services.
