Using this table lamp is a breeze. Just plug it into a power outlet and use the in - line rotary on/off switch on the cord to turn the light on or off. When it comes to bulbs, make sure to use a 40W E12 candelabra base type C bulb. Although it's compatible with LED bulbs, you'll need to buy the bulb separately. Since no assembly is required, you can start using it right away. For maintenance, gently dust the lamp regularly with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials as they may damage the metal finish or the stained glass. You can use this lamp at home or in a commercial setting. Enjoy the soft, warm light it provides and the cozy atmosphere it creates in your space.
