Shunted Vs Non Shunted Lamp Holders
There is a huge difference between shunted and non shunted t8 and t12 sockets using the wrong type can end with disastrous results.
Shunted vs non shunted lamp holders. Rapid start programmed start and dimming ballasts use non shunted lampholders to provide power through the lamp s cathodes before the lamp is turned on. Sunco uses non shunted tombstones for our direct wire led t8 tubes. This provides a single track for the electrical current to travel from the ballast through the tombstone or socket and to the lamp s pins. Their contacts are not connected or joined.
Shunted sockets have internally connected electrical contacts. Don t worry with our video guide we explain the difference. In non shunted lampholders or tombstones current flows through multiple paths and in shunted tombstones current flows through a single path. This type of socket is used with sunco led t8 tubes and also in dimming ballasts programmed or rapid start ballasts.

This unique construction allows direct connection with both non shunted and shunted sockets those that have the wire holes only on one side. While the non shunted sockets have separate contacts or points of entry for the wires creating two tracks for the electrical current to travel. But frankly you may be better off buying new shunted sockets to avoid a lot of wiring work especially if you have a large number of sockets to manually shunt.
Shunted sockets have contacts that are joined or connected. This provides a single track for the electrical current to travel from the ballast through the tombstone or socket all the way to.
