LED Tube Installation

LED Tube Wiring Diagram

LED T8 Tubes Wiring Diagram

1) Turn off electric power before LED Tube Lights installation

2) For refitting old fluorescent lamp with a single-side-power-input LED tube, please re-connect your wire as the following diagram.

3) For diagram A1 loop with magnetic ballast & starter, please remove the starter first. Then connect line N and Line L to the same side socket but separately. Now you can put on the LED tube and turn it on. And the loop has been changed into the one as showed in diagram A2.

Note: You can just keep magnetic ballast as it was. However, it’ll consumer some power. For saving energy, it’s still suggested to remove it if your labor cost is not so high.

4) For diagram B1 loop with electronic ballast, please remove the electronic ballast first. Then connect line N and Line L to the same side socket but separately. Now your LED tube light is ready to work. And the loop has been changed into what showed in diagram B2.
