Single 15-watt clear C7 bulb for lamps.
Sold in units of 4.
To replace the bulb, first remove the wire from the electrical outlet so there is no current running through the wire. Then gently pull out the cord from the base of the lamp. Unscrew the old bulb & replace with a new 15 watt clear C7 bulb. Once the bulb has been replaced, put the cord back in the lamp.
