Keystone - Since 1945By changing your current light sockets to NON-SHUNTED G13 medium bi-pin and bi-passing the current ballast, Keystone LED T8 tube lights can be utilized in fixtures that currently have fluorescent lighting: Commercial/Office Space Retail Installations  Hospitals Airports and Train Stations Residential Installations Food Service Locations Schools and Cold Storage. 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. 

This series of Keystone LED tube lights has a shatterproof coated glass tube and a frosted lens that eliminates pixelation. There is no risk of broken glass - making them ideal for food service (in fact they are ETL Sanitation Listed NSF/ANSI Standard 2 - Food Equipment) applications. Keystones Direct Drive LED T8 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. (SPECIAL NOTE: These Fluorescent to LED Retrofit T8 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). For retrofit installations, bi-pass the existing ballast by cutting the wires and instead connect the 120 or 277 volt 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.
