These 2' LED T8 tubes are the long-lasting alternatives to F17T8 fluorescent tube lights. The single-ended ballast-bypass tube light bulb can be used in direct-wire fixtures. It emits 1,150 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. The energy-efficient LED light uses just 10 watts of power—significantly less than the 17 watts of an equivalent fluorescent tube light. With a life expectancy 5 times as long as fluorescent tubes, the LED T8 tube reduces costly repairs, disposal fees, and the need for replacements. Price per bulb, 4-pack, 25-pack, or 50-pack. It's perfect for 2' x 2' troffers in basements, kitchens, cabinets, hospitals, workbenches, and more.

T8B2-xK10S-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.


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.

Great Service, Charged Sales Tax on Shipping.

I was very happy with my purchase. I would have given a 5 star review except for a couple of issues. In addition to charging me state sales tax on the LEDs that I purchased, Superbright LEDs charged me state sales tax on the shipping. My state, Minnesota, does not collect sales tax on shipping. The other issue was that of the 6 48 inch LED fluorescent tube replacements that I ordered, when my shipment arrived, two were broken, and two functioned only briefly before failing completely. I contacted customer service at Superbright LEDs, and they promptly shipped me 5 additional replacement LEDs , and they provided a return shipping label for me to return the damaged products. The 2nd package that they shipped was packaged and labeled much better than the original package. All of the LEDs that I received in the replacement package arrived in excellent condition, and they functioned correctly after installation.

After a month, looking good.

So far, so good. Installed three of these, one each in three fixtures. Pleased that each tube comes with wiring instructions. I stapled them to the basement joists next to the fixtures, so the next owner can see what has been done.
