ETi’s Universal NON-Shunted Bi-Pin T8 Socket Tombstone is designed specifically for retrofitting 2, 3, or 4 lamp fluorescent fixtures with direct wire LED tubes. Non-shunted sockets have separate contacts – or points of entry for the wires – creating two tracks for the electrical current to travel. Non-shunted sockets have contacts that are not joined or connected. These sockets are used in fluorescent fixtures with programmed start, rapid start, and dimming ballasts. When retrofitting a fluorescent fixture with a single lamp or replacing an old socket, use ETi’s individual non-shunted sockets.
