This series of Keystone LED T8 tube lights have a frosted, plastic lens and an aluminum backing. There is no risk of broken glass making them ideal for food service, residential and school applications. The lumen output of an LED T8 tube is different than that of the more familiar fluorescent T8 lamp. Fluorescent lamps deliver lumens in a 360° pattern, where many of the lumens are wasted because they are directed upwards. With LED T8 tube lights, the delivered light is more directional, so fewer lumens are required to achieve similar or greater levels of usable light output.
The aluminum backing provides excellent heat dissipation while offering structural rigidity to prevent bowing. Keystones Direct Drive LED tubes eliminate the need for an external driver or ballast. For new construction installations, simply connect the 120-277V line voltage directly to the sockets. Please Note, for retrofit installations, bypass the existing ballast by cutting the wires and instead connect the 120-277V line voltage directly to the sockets. No ballast or driver is required. Making your retrofit project even easier, Keystone offers a four (4) socket, non-shunted wiring harness - complete with the quick disconnect connectors. SPECIAL NOTE: These Fluorescent to LED Retrofit tubes require NON-SHUNTED medium bi-pin G13 sockets. It is always prudent to replace the 'tombstone' sockets any time you retrofit a light fixture. For the Keystone Technologies LED T8 tubes be sure to replace your tombstone sockets with NON-SHUNTED sockets.
