If you really can't screw it down, you can consider wrapping the bulb in a towel and breaking it, and then clamp the edge of the screw mouth with needle-nose pliers, shake it left and right first, and then unscrew it when it is loose, of course, you must cut off the power supply in advance, so if it doesn't work, then you can only change the lamp mouth together.

The lamp ports of energy-saving lamps are usually Luokou, so just buy a Luokou incandescent bulb and install it.
Do not take it.
The dimming principle of incandescent lamps is very simple, that is, a variable resistance (knob to adjust the size of the resistance) The principle of energy-saving lamps is electrode discharge. The dimming condition is to control the ionization of the gas in the lamp, and the adjustment is to control the discharge frequency and wax sensitivity (adjustable ballast). >>>More
LED lights need to be lit driver, the driver is the output of constant current current switching power supply, the quality or debugging is not good, when the output current is abnormal, there is often a very low frequency (a few hertz) low-frequency oscillation, LED light flashing phenomenon. When purchasing, you should test before purchasing, if you use DC to drive the LED light directly, there will be no light flickering phenomenon. >>>More
Remove it, connect the broken wire, wrap it with insulating tape, and install it again, OK.
The bathroom should have no special needs for lighting other than illumination. Personally, I think it is best to use energy-saving and high-brightness LED recessed panel lights.
