Overview
These 15-watt LED T8 tubes are the energy-saving alternatives to 32-watt fluorescent tube lights. The 4' ballast-compatible/ballast-bypass tube light bulb can be used in direct-wire fluorescent fixtures or to replace T8 tubes in ballasted fixtures. It emits 1,725 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.

Connection Types
Type A/B Hybrid LED Tube Lights are a versatile option. They can be connected as a true plug-n-play replacement for a flourescent tube light using a Dual-End Type A configuration, or they can be wired as a ballast bypassed Single-Ended Type B Tube Light.

Single Ended (Type B Configuration)
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

Dual Ended (Type A Configuration)
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
Type A/B LED Tube Lights offer wiring options for using existing in-line ballast, or bypassing the ballast. The Dual-End Type A configuraiton allows the light to be powered on using the existing ballast, the Single-Ended Type B configuration allows the ballast to be bypassed entirely.
How To Wire Dual-End Type A:

How To Wire Single-End Type B:

Socket Wiring
The shunting configuration for Type A/B Hybrid Tube Lights is dependent on if you want to use the light in a Dual-End Type A configuration, or a Dual-End Type B configuration.
Shunted (Type A Dual-End)
Both contacts in the same socket (tombstone) are connected/bridged and are the same polarity—either L or N.
Non-Shunted (Type A Dual-End, Type B Single-End)
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. A non-shunted socket is required for single end Type B installations.
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.

Why return broken tube?
3 stars is Not about the product. The fact that on of the tubes arrived broken isn’t really an issue. The fact that I had to take time out of my day to take the broken tube to the post office to return it is what the 3 stars is for. Not sure why they wanted to pay for return shipping and then pay to ship me a replacement.
Great product, needs better packing to ship them.
These are just very good, just like every purchase that I have made from Superbrightleds. They are instant on and good light. The frosted lens spreads it out well. They are pinned opposite of the ones that I purchase 2 years, but no big deal. Packaging is still not good enough to deal with what the freight company does, but superbrightleds customer service has always been great.
