LANSDALE, PA (SEPTEMBER 17, 2025)
Keystone Technologies, the leader in LED lamps, is expanding our line of T8s with two shatterproof models: a UL Type B (ballast bypass) tube and a UL Type A&B (hybrid) tube.
These shatterproof T8s expand our best-selling 4-foot tube offering. The DirectDrive model—UL Type B—includes three models with single- or double-ended wiring: 10.5W, 14.5W, and 15W. The ComboDrive (UL Type A&B) model comes in a 13W model.
Aside from being durable, glass-coated, and shatter-resistant, all feature 5 built-in CCT selectable options.
The rugged coating supports safety-critical installations such as food service, healthcare, education, and manufacturing. These models retain performance consistency while delivering additional protection from glass breakage during transport or use. They’re the go-to lamp for high-safety environments.
Keystone offers the widest selection of LED tubes on the market, including all four UL types, T5 and T8 diameters, a range of dedicated color temperatures, selectable CCT versions, Sign Hero sign tubes, and even our distinctive UL 924 Emergency Tube, all in lengths to meet your requirements.
