Using this table lamp is easy. First, find a suitable spot in your room. The lamp doesn't need any assembly, so you can just place it right away. Then, insert a 40W E12 candelabra base type C bulb (you'll need to buy it separately). You can also use an LED bulb as it's fully compatible. To turn the lamp on or off, use the in - line rotary switch on the cord. When it comes to maintenance, simply dust the lamp regularly with a soft cloth. For the glass shade, you can gently wipe it with a damp cloth. Keep in mind that although it's suitable for commercial use, avoid placing it in extremely humid or dusty environments. This will help keep your lamp looking great and working well for a long time.
