Using this lamp is easy. First, find a suitable spot for it. Since it's a table lamp, a side table or a nightstand would be great. Make sure there's an electrical outlet nearby. Then, insert two 60W E26 medium base type A bulbs into the sockets. You can use CFL or LED bulbs too as the lamp is compatible with them. To turn the lights on or off, simply pull the double pull-chain switch. You can control each light separately, which is really handy.
As for maintenance, keep the lamp clean by gently dusting it with a soft, dry cloth. Avoid using abrasive cleaners or water directly on the lamp, especially the stained glass parts. If the lamp gets dirty, you can use a slightly damp cloth to wipe it carefully, but make sure to dry it thoroughly. Since no assembly is required, you don't have to worry about any parts coming loose. And because it's suitable for commercial use, you can place it in offices or shops as well. Just enjoy the warm and stylish lighting it provides.
