WARNING: Make sure that you have cut off the power before installation!
Electrical wiring diagram of LED tube:
The working mechanism of LED tube is different from that of fluorescent tube. When installing LED tube on existing fluorescent bracket, you need to bypass or remove the ballast and remove the starter within the lamp bracket to avoid the negative impact on LED tube light and its efficiency.
Further more, the installation way is different for inductive ballast and electronic ballast:
●Lamp bracket of inductive ballast: Remove the Starter, Short-circuit the both ends of Inductive ballast.
●Lamp bracket of electronic ballast: Open-circuit the input wire of ballast, connect the two pairs of output wires of ballast to junction box.
