When To Use Shunted Tombstones And When To Use Non-shunted Tombstones
Here we provide you some options to the shunted and non-shunted socket. Very important to make sure that the tombstone configuration matches the type of lamp you will be using. Pls check the following table:
Bi-pin lamp type
Shunted or Non-shunted
T12
Non-shunted
T8 with rapid-start, programmed-start, or dimming ballast
Non-shunted
T5 with rapid-start, programmed-start, or dimming ballast
Non-shunted
T5 with instant-start ballast
shunted
T8 with magnetic ballast
Non-shunted
T8 plug-and-play
shunted
T5 plug-and-play
shunted
In a word, we can get the conclusion :
1.LED tubes that work with existing T8 instant-start ballasts use shunted tombstones.
2.LED tubes that work with existing T8 programmed rapid start ballasts use non-shunted tombstones.
3.LED tubes that do NOT use a ballast work with non-shunted tombstones.
