4Ft LED T8 Tube | Ballast Bypass Type B | 2.250 Lm | 120/277V | 4.000K CCT | Commercial LED CLT97-18WB-40K

The F18T8/4000K 4ft LED T8 Tube (Type B Ballast Bypass) – Model CLT97-18WB-40K is a high-performance lighting solution designed to replace traditional fluorescent T8 lamps with improved efficiency, brighter output, and long-term reliability. Delivering 2250 lumens of neutral white 4000K light, this LED tube is ideal for offices, retail spaces, warehouses, and commercial environments that require balanced and consistent illumination.

Engineered as a Type B (ballast bypass) LED tube, this lamp connects directly to line voltage, eliminating the need for a ballast. This reduces energy losses, lowers maintenance costs, and removes ballast-related failure points, ensuring a more reliable lighting system over time.

Operating at 18 watts, this LED tube provides strong brightness while significantly reducing energy consumption compared to fluorescent alternatives. The 200° beam angle and 320° field angle deliver wide, even light distribution, minimizing shadows and improving visibility across large work areas.

With a standard 4-ft (47.72 in.) design, this LED T8 tube fits most fixtures and operates within a 120–277V universal voltage range, making it suitable for a wide variety of commercial and industrial applications. Built for durability, it features a 50,000-hour lifespan and is backed by a 5-year warranty, ensuring long-term performance and cost savings.
