Replacing a table-lamp bulb is straightforward when the lamp is unplugged and the replacement matches the socket, voltage, shape, and fixture rating.
Disconnect first
Unplug the lamp and allow the old bulb to cool. Do not rely only on the switch.
Match the bulb
Check the socket type and maximum wattage printed on the lamp. Use an LED with suitable brightness and color temperature for the room.
Inspect the socket
Look for scorching, looseness, or a damaged cord. Stop using the lamp if the socket or plug is heat-damaged.
Test safely
Install the bulb without force, reconnect power, and confirm the shade is not touching the bulb.
