You can turn the lamp on or off using the ON - OFF rotary switch. The built - in USB port is great for charging your devices like phones or tablets. Just plug your device's charging cable into the USB port. When it comes to maintenance, make sure to routinely wipe the lamp's exterior with a soft, clean cloth. Use glass cleaner to keep the glass parts looking clear. For the metal surface, apply car wax twice a year as it helps preserve and protect the finish.
