H&B Luxuries 4FT LED T8 Ballast Bypass Type B Light Tube, 18W, UL-Listed for Single-Ended & Dual-Ended Connection, 2340lm, T8 T10 T12, UL & DLC - 4000K (5Pcs)

✅【 Ballast Bypass】 These tubes must be installed using the ballast bypass method. Use the instructions provided to remove the ballast from your fixtures and 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 efficiency and energy saving】: the light brightness is equivalent to 40W of lamp tube, but only 18W of consumption, saving 50% of electric energy. UL Listed for better quality, safety, reliability and have longer lifetime up to 50,000 hours than halogen/incandescent/fluorescent bulbs.

✅ 【 Shatterproof】 These led t8 are designed with a frosted shatterproof film protected glass housing which allows for safe installation in fixtures, with or without wire guards.
