Confused by LED T8 tube options? Unsure if you need single-ended or double-ended LED tubes? Orilis can help by simplifying the jargon!
Understanding Single-Ended and Double-Ended LED Tubes
In a nutshell, single-end powered LED tubes are wired to one end of the tube only, while double-end powered LED tubes are wired to both ends. It's important to note that these tube types are not interchangeable, as the wiring will be different for each type.

Double-Ended LED Tube
A double-ended LED tube is a tube where the live and neutral pins are located on the opposite sides of each tube. This design is similar to fluorescent tubes, making retrofit applications easier when using double-ended LED tubes.
When upgrading to LED tubes using an LED Retrofit Kit, you can reuse the existing tombstones if they are in good condition. This can help reduce the average retrofit installation time. However, it's essential to check the tombstones for any damage. Old tombstones may be broken due to long exposure to heat or frequent tube replacements. If damage is found, it is best to replace them.
Single-Ended LED Tube
A single-ended LED tube is a tube where the live and neutral pins are located on the same side of the tube. This side is known as the "Input" end. You can easily identify a single-ended tube by looking for the L/N or AC INPUT sticker at the end of the tube.
Since single-ended powered tubes use only one side of the tube, both live and neutral power will be on the same side but with different pins. The "L" indicates the pin for live power, while the "N" indicates the pin for neutral power.
If you are installing a single-ended LED tube as part of an LED Retrofit Kit into a fluorescent fixture, you will need to replace the existing fluorescent, shunted tombstones with non-shunted tombstones on at least one side of the fixture, specifically the 'live' or powered end of the fixture.
