Overview
These 12-watt LED T8 tubes are the energy-saving alternatives to 32-watt fluorescent tube lights. The 4' ballast-bypass tube light bulb can be used in direct-wire fixtures. It emits 1,600 lumens of cool or natural white illumination. Unlike fluorescent lights, this LED T8 tube turns on instantly—even in cold weather—and is simple to dispose of because it contains no harmful mercury. With a life expectancy 5 times as long as fluorescent tubes, the LED light reduces costly repairs, disposal fees, and the need for replacements. Price per bulb, 4-pack, 25-pack, or 50-pack. It's perfect for basements, offices, schools, hospitals, factories, and more.

T8B-xK12S-GF Supported Electrical Configurations
Connection Types
Type B Single-End LED Tube Lights are wired to a single set of pins at one end of the tube light itself.
Single Ended
Electrically connected from one end of the tube, one pin connecting to line and one to neutral. This type requires non-shunted sockets and rewiring
Ballast Compatibility
Bypassing ballast is required for Single-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
Type B Single-End LED Tube Lights require bypassing of the ballast and rewiring sockets in one end of the fixture to a non-shunted configuration.
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.

Dim bulbs
Not 1600 lumens each as advertised. 4 of them in a single fixture is less bright than the 15 year old florescent bulbs. Very disappointed!
