LED Glass Tube Type B 120-277V 2250 Lumens UL Listed | 18W 4FT Milky

4FT T8 LED Glass Tube ¨C Type B (Ballast Bypass)

Engineered for high-output commercial, industrial, and institutional lighting retrofits, this 4FT 18W LED Glass Tube Light delivers clean, high-efficiency illumination to replace traditional 32W T8 and T12 fluorescent lamps. Producing 2,250 lumens at an energy-saving efficacy of 125 lm/W, this milky frosted glass tube provides ultra-smooth, uniform light distribution for office troffers, educational facilities, healthcare spaces, warehouses, and retail aisles. Built with universal AC120–277V Type B ballast-bypass technology, it wires directly to line voltage—eliminating ballast compatibility issues, power loss, and ongoing ballast maintenance costs.

• 2,250 High-Efficacy Lumens (125 lm/W): Supplies bright, continuous illumination while consuming only 18W, cutting energy usage by over 43% compared to standard 32W T8 fluorescent tubes.

• Direct Ballast Bypass (Type B): Connects directly to AC120–277V line voltage, removing electronic or magnetic ballasts as failure points and maximizing overall fixture efficiency.

• Full-Glass Body with Milky Frosted Lens: Features an expansive wide-beam angle with a frosted milky diffuser that completely eliminates harsh direct glare, shadows, and visible LED hot spots.

• UL Listed: Fully tested and certified to meet stringent North American safety, electrical performance, and building code compliance standards.

• Universal Commercial Voltage (AC120–277V): Industrial-grade internal driver operates seamlessly across standard 120V, 208V, 240V, and 277V electrical systems.

• Shatterproof Film Coating: Rigid glass construction enhanced with a protective shatter-resistant coating to prevent glass fragmentation in food preparation, healthcare, and active industrial environments.

• Standard G13 Medium Bi-Pin Base: Fits securely into standard 4-foot G13 sockets for fast, straightforward retrofits in fluorescent strip lights, troffers, and wrap-around fixtures.

• Instant-On & Silent Performance: Powers on immediately at 100% brightness without humming, flickering, buzzing, or cold-temperature startup delays.
