The Keystone 18W U-Bend LED is a line-voltage (Type B) lamp designed to operate independently of a ballast by connecting directly to the 120–277V power source. By eliminating the ballast, you remove a common failure point and significantly reduce long-term maintenance costs. This is an ideal retrofit for 2x2 troffers in healthcare facilities, commercial offices, and retail spaces.
This 18W LED lamp delivers 2,200 lumens, serving as a high-efficiency replacement for standard 32W T8 U-Bend fluorescent tubes. It provides a crisp, uniform light distribution while reducing energy consumption by over 40%. This transition supports 2026 Code Enforcement for Lighting Power Density (LPD) targets in commercial "office and classroom" environments.
This U-Bend LED is NSF/ANSI 2 rated, certifying it for use in splash zones and food service environments. The lamp's construction prevents the accumulation of bacteria and resists corrosion from cleaning agents. When combined with its shatterproof design, it is an essential component for maintaining safety and sanitation standards in commercial kitchens and cafeterias.
The lamp is available in 3500K (Neutral White), 4000K (Cool White), and 5000K (Daylight). The 4000K and 5000K options are the standard for professional environments to enhance alertness and task performance, while 3500K is often specified for public areas where a more balanced, inviting light is preferred.
The lamp features a shatterproof coating over a glass housing. This design combines the thermal stability and rigidity of glass—preventing the sagging often associated with older plastic LED models—with the safety of polycarbonate. If the glass breaks, the coating contains all fragments, ensuring site safety in high-traffic commercial zones.
This fixture is designed with a standard 6-inch leg spacing, making it a universal fit for the majority of 2x2 fluorescent troffers. The G13 Medium Bi-Pin bases ensure a secure connection into existing lampholders, facilitating a straightforward conversion from fluorescent to LED technology.
Rated for 50,000 hours of operational life, this LED lamp lasts up to 2.5 times longer than legacy fluorescent U-Bends. It is backed by a 5-year warranty from Keystone Technologies, covering the integrated driver and LED array. This long-term reliability ensures a stable ROI and reduces the frequency of maintenance cycles in critical commercial infrastructure.
