Using your new table lamps is easy. First, do the partial assembly. Attach the white cone linen shade to the blue resin base using the threaded uno shade fitter. Then, plug in the 72 - inch cord to a power source. You can use the 3 - way switch to adjust the light as you like. These lamps are great for both home and commercial use. For safety, always make sure they are UL - listed. When it comes to maintenance, simply dust the lamp base and shade regularly with a soft cloth. Avoid using harsh chemicals or abrasive materials that could damage the lamp. Also, make sure to place the lamps on a stable surface to prevent them from tipping over.
