What is the reason for the newly bought double-headed European wall lamp that is not on one side after installation?
Not long ago, I just bought a double-headed European wall lamp. I am going to install it today. After installing it, I tested it and found that it is not bright while it is bright. What is the reason? How to deal with it? If you want to know the answer, please continue to look down. 1.
First, you should check whether the bulb is good or bad, see if there is a problem with the bulb, and test it with a new bulb. 2.
Secondly, check whether the contact is good or not. This kind of European-style wall lamp is usually a screw cap, and the bulbs are exchanged.
If the other one is on, it means that the bulb is broken. If it is still not lit after the swap, there is a problem at the screw. It may be that the screw is loose, at this time, gently twist the bulb clockwise with your hand to see if it is still not bright after twisting. Turn off the power supply and pull the spring copper sheet inside the screw out 2 ~ 3mm test it again. 3.
If the above methods do not work, it is that there is a problem with the lamp cap fittings or the circuit inside the lamp itself is not connected properly. At this time, an electrician should be found to re-check or send the lamp back to the factory for replacement.
