4FT LED T8 Ballast Bypass Type B Light Tube, 18W, Single-Ended & Dual-Ended Connection, 2340LM, G13 Base,T8 T10 T12 Fluorescent Bulbs Replacement, UL & DLC - 4000K (60Pcs)

Single or Double-Ended Connection: This tube is UL-Listed and DLC-Qualified for installation with a single-ended or double-ended connection. It is suitable for garages, warehouses, office storage areas, fabrication floors, retail spaces, and hospitality settings. Ballast Bypass: These tubes must be installed using the ballast bypass method. Follow the included instructions to remove the ballast from your fixtures and directly wire your new T8 tubes. Replacing fluorescent tubes (T8, T10, T12) saves both time and money, as ballasts inevitably fail over time and need replacement. Ballasts also consume electrical power; bypassing them results in additional energy savings. High efficiency and energy saving: The light output is equivalent to a 40W fluorescent tube, but it consumes only 18W, saving 50% of electrical energy. UL Listed for enhanced quality, safety, and reliability, with a rated use of up to 50,000 hours, outperforming halogen, incandescent, and fluorescent bulbs. Shatterproof: These LED T8 tubes are constructed with a frosted, shatterproof film-protected glass housing, allowing for safe installation in fixtures with or without wire guards
