What is the reason for the flickering lights in the hotel room?

We need to check the wiring of indoor lights and power cords. Be sure to cut off the power supply before checking the line to avoid danger. Then open the lampshade and check whether the lamp connector is loose. You can take the lamp down and put it back on. Many lights are not bright enough because of poor contact or loose bulbs. You can also check whether there is blackening at the connection of the lamp tube. If yes, the damaged lamp may be broken. It is possible that the lamp bead is broken, and the indoor lamp is connected in series. If one lamp bead is broken, all the lamp beads can't be used. It is also possible that the solder joint is off-welded, resulting in damage. In addition, the damage of the lamp is likely to be the inferior lamp bought by the buyer, if it is not used for a long time.

If it is not the above two problems, it is recommended to check the ballast. See if the ballast has any signs of burning or smell.
