For replacement of tubes, wiring, and lampholders, it is important first to understand the differences between dual power input LED tubes and single power input LED tubes. Dual input power tubes are wired to both ends of the tube with the live power on one end and the neutral power on the opposite end. Single input power tubes are wired to only one end of the tube with the live power to one terminal and the neutral power to the second terminal on the same end. If you are retrofitting an existing fixture by removing the ballast, but using existing lampholders, the lamp- holders may be shunted or non-shunted based on the type of ballast. Therefore, we must understand the differences between shunted and non-shunted lampholders, because dual input power tubes require shunted lampholders and single input power tubes require non-shunted lampholders. A shunted lampholder has both contact sides connected (dead short) and usually the wiring connection only on one side. A non-shunted lampholder has separate contacts with wiring connections on both sides. Check continuity with an OHM meter across the terminals to be certain.

T8 Linear Replacement Tubes: We Make it Simple
At Gen One Four we want to make your transition from Fluorescent to LED as simple as possible. We will pro-vide the components you need based on your preferences: 1. LED Tubes only 2. LED Tubes, lampholders, and wiring 3. Complete LED fixture (troffer) assembled with tubes, wiring etc. 4. Alternative LED Panel type drop in replacement fixture.
Items 3 and 4 only require removal of the existing fixture and installation of our drop in LED replacement trof-fer or panel light.
For replacement of tubes, wiring, and lampholders, it is important first to understand the differences between dual power input LED tubes and single power input LED tubes.
Dual input power tubes are wired to both ends of the tube with the live power on one end and the neutral power on the opposite end. Single input power tubes are wired to only one end of the tube with the live power to one terminal and the neutral power to the second terminal on the same end.
If you are retrofitting an existing fixture by removing the ballast, but using existing lampholders, the lamp-holders may be shunted or non-shunted based on the type of ballast. Therefore, we must understand the differences between shunted and non-shunted lampholders, because dual input power tubes require shunted lampholders and single input power tubes require non-shunted lampholders.
A shunted lampholder has both contact sides connected (dead short) and usually the wiring connection only on one side. A non-shunted lampholder has separate contacts with wiring connections on both sides. Check continuity with an OHM meter across the terminals to be certain. The shunted lampholder will show continu-ity; non-shunted will not.
Next we will look at the wiring process for T8 Dual input power LED Replacement tubes.

TO REWIRE FOR T8 LED TUBES: 1. Remove power from fixture. Use a meter to con-firm power is off. Cut the wires to the ballast and remove ballast.
2. Using a wire nut (I like the plug in connectors) connect the black (live) power wire to the red and blue wires, (Figure 4) and the white (neutral) power wire to the yellow wires (Figure 5). Confirm the Ground wire is con-nected properly to the fixture (Figure 6).
STEP 3 FOR DUAL INPUT T8 LED TUBES ONLY: (For single input skip to step 4) 3. Then confirm the connection of the red and blue wires to individual lampholders to one end (Figure 7) and the yellow wires and jumpers to the opposing lampholders (Figure 8). Lampholders should be shunted for dual input tubes. Skip steps 4-6 and go to step 7 to finish.

STEPS 4-6 FOR SINGLE INPUT T8 LED TUBES ONLY: 4. Now determine which end of the fixture you designate as the power input side. On the power input side of the fixture, replace the shunted lampholders with non-shunted lampholders. You can confirm whether shunt-ed by using a continuity meter (Figure 13) across the inside connection of the lampholder.
On the non power end of the fixture, you do not need to replace the lampholders. Remove the wiring from the non-input end lampholders.
5. Now connect the red and/or blue wires and jumpers (I mark with black tape to show connection to black live wire) to one side of the individual, non-shunted lampholders on the input power end (Figure 15) and the yellow wires and jumpers (I mark with white tape to show connection to white neutral wire) to the second side of the individual, non-shunted lampholders on the input power end.
6. For safety, at this point I use a meter to confirm all connections are secure and correct.
7. Replace the cover and install LED tubes. For single input, determine which end of the LED tube is the power end and and install tubes in the input power lampholders (Figure 16).
