Single end power LED tube and Double end power LED tubes

If it is single ended powered LED tubes, need to power only one end. This type of installation is referred to as unshunted. If double ended powered LED tubes, need to power both ends, one with line source, the other end with neutral. This type of installation is referred to as shunted.

Led tubes are a better choice than those traditional light sources because they are more economical, energy efficient, conserve power, lower our electricity bills and moreover get those hazardous fluorescent or other potentially dangerous incandescent lights out of our lives for good. Getting led lights installed is the best way to save money and go green to protect the earth and your own lives as well.

Normally there are two ways of using LED tubes to replace old fluorescent tubes.

First, check your old fluorescent tube is double ended power or just single ended power. If your old fluorescent tube is double ended power, here is the installation guidance for double ended power LED tubes.

Step1: Cut off the power for traditional tubes (Note: As just turn off switch for not sure power totally off from the lighting fixture, we suggest removing the fuse or cut off the circuit interrupter)
Step2: Remove the traditional tube from the holder.
Step3:For replacing original tube, open the cover of the tube holder, seeing the wire connected situation in holder, remove the starter and ballast.
Step4: Put the cover back to the holder, and then install LED tube into the holder, connect two wires to LED tube.

If your old fluorescent tube is single ended power, here is theinstallation instruction:

1.The steps of inductive fluorescent T8 tube with holder

Step one: Shut off the power supply, removal of fluorescent lamp.
Step two: Remove the starter.
Step three: Install short circuit device, instead of the starter.
Step four: Installation of the LED lamp replacement.

2. The steps of Electronic fluorescent T8 tube with holder

Step one: Shut off the power supply, removal of fluorescent lamp.
Step two : Removal of electronic ballasts, connecting wire into a single ended power supply.
Step three : Installation of the LED lamp replacement.

In fact, it is very easy to install a LED tube. By using LED lights, it will save your money and save energy. Now, most governments are advocating to use LED lights, and most European countries are advocating to use single ended power LED Tubes, as it is safer than double ended.
