SPECIAL NOTE: The Keystone KT-SOCKET-T8-U-T-2-W Direct Drive Wiring Harness is for use in NON-SHUNTED G13 Medium Bi-Pin applications ONLY.
Utilize the KT-SOCKET-T8-U-T-2-W Direct Drive Wiring Harness to replace your current shunted or non-shunted tombstone sockets or in your LED T8 tube light retrofit project. A common LED T8 retrofit bulb, like the Keystone Direct Drive series, powers the LED T8 tube from a single end ONLY. In these cases manufacturers require that you do not install the tube lights in a fixture with shunted lamp holders (found in all fixtures using instant start ballasts). If the current lamp-holders are shunted, remove them and replace them with non-shunted lamp holders.
The Keystone KT-SOCKET-T8-U-T-2-W Direct Drive Wiring Harness is pre-wired with two (2) tall, non-shunted sockets and the power quick connect. If your project calls for less than four lamps simply remove the excess sockets from the harness.
