Using this table lamp is a breeze. First, if it's a new purchase, you'll need to do partial assembly. Attach the shade to the base using the spider shade fitter. Then, plug in the 72 - inch black cord to a power source. You can use the rocker switch to turn the lamp on and off. To charge your electronic devices, simply connect them to the built - in USB port. Adjust the swinging arm to direct the light where you want it, and you can also adjust the metal shade for different lighting angles. When it comes to maintenance, use a soft, dry cloth to clean the lamp regularly. Avoid using harsh chemicals as they may damage the black metal finish. Keep it away from excessive moisture. If you plan to use it in a commercial setting, make sure the power supply is stable. And remember, you'll get the exact product based on the options you choose on the page.
