When you notice that your ceiling lights are less bright, but still emit a faint light, it usually means that the light fixture is faulty. In order to find out the cause, you can try removing the lampshade and checking if the bulb is black or damaged. If there is no problem with the bulb, then it is possible that the stabilizer of the lamp is damaged or not installed properly.
To solve the problem of insufficient brightness of ceiling lights, we recommend that you replace damaged bulbs and stabilizers. Although the structure of the ceiling lamp is relatively simple and not complicated to repair, you need to judge whether the fault can be repaired before repairing. Servicing ceiling lights is a foundational skill in light fixture repairs, but if you're not familiar with these operations, it's important to seek professional help.
While these issues may not be complicated for skilled electricians, to ensure safety and repair quality, we recommend that you look for experienced repairers on a professional repair platform to complete the repair work.
In general, when repairing with LED lights with patch combinations, it is necessary to pay attention to the consistency of their driver power. You can unplug the working drive plug and try plugging it into the LED chip socket that is not lit. If the LED chip glows normally after replacing the driver, then the original driver may be damaged. If it still fails to light up after replacement, it may be a problem with the LED chip itself.
