LED Light Tube T8 Installation

LED Light Tube T8 Wiring Diagram:

t8 led tube wiring diagram

1) Please turn off electric power before LED Tube Lights installation

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

3) For diagram A1 loop with inductive ballast & starter, after removing the starter, LED tube can be installed directly into the G13 base. Then LED tube light is ready to work. And the loop has been changed from A1 to A2.

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

4) For diagram B1 loop with electronic ballast , please remove the electronic ballast first. Then connect L and N to the two sockets of the G13 base separately. Now your LED tube light is ready to be turned on. And the loop has been changed into the one showed in diagram B2.
