T8BD-xK12S-GF Supported Electrical Configurations

Connection Types

Type B Dual-End LED Tube Lights can be placed into unmodified sockets and simply need to be oriented to match the existing polarity of the fixture.

Dual Ended

Electrically connected on both ends of the tube, with one end connecting to line and one to neutral. This type can use shunted or non-shunted sockets. As with the original bulbs these are replacing, one end of the tube connects to L and the opposite end to N—one end should not be connected to both.

Ballast Compatibility

Bypassing ballast is required for Dual-End Type B LED Tube Light installations and will not function if connection to the ballast is left intact. This is a popular solution when relamping, due to the likelihood of an eventual ballast failure.

How To Wire:

Socket Wiring

When installing Type B Dual-End LED Tube Lights in a fixture which previously had a fluorescent tube light you can simply install the light leaving the sockets in a shunted or non-shunted configuration.

Shunted

Both contacts in the same socket (tombstone) are connected/bridged and are the same polarity—either L or N.

Non-Shunted

Contacts in the same socket (tombstone) are split, but can be either the same polarity or opposing polarity depending on the way the socket (tombstone) is wired.

Determining Shunted or Non-Shunted

Below are some typical examples of how shunted or non-shunted sockets might look. You should always check the socket terminals with a multimeter before installing bulbs or rewiring. If the two sides of a socket have continuity, then the socket is shunted regardless of appearance.

Need To Wire Differently?

LED tubes lights can be wired with or without ballast, and from either end depending on the tube type.
