How to change the lamp tube by yourself

Replacing the lamp tube is divided into the following five steps:

1, make sure the power is off. If the on-off state of the power supply cannot be confirmed due to damage, it is helpful to check whether there is current passing through the conductive part at the lamp interface with the help of an electric pen.

2. Remove the damaged lamp tube. When taking the lamp tube, one hand holds the lamp holder, and the other hand holds the lamp tube and pushes it to the other side. After the two contacts of the lamp tube are separated from the lamp holder, it is taken out downwards.

3. Install the lamp. Align the wiring pins at both ends of the lamp tube with the mounting seam of the lamp holder, press the lamp tube firmly, and then rotate the lamp tube until it feels tightly connected with the lamp holder.

4. Check the lamp. Turn on the power supply and observe whether the new lamp tube glows. If the light of the lamp tube is normal, the installation is successful. If the light is not on or flashing, please remove the light again and install it with other lights.

Note: Wrap the damaged lamp in a bag or paper and put it in the dustbin to avoid scratching yourself and others.
