Using this lamp is easy. First, since it's hardwired, you'll need to have it installed by a professional electrician. Once it's installed, simply connect it to a power source and you're ready to enjoy its beautiful lighting. When it comes to the bulb, make sure to use one with an E26 or Type A socket and a maximum wattage of 60. As for maintenance, you can gently wipe the glass and brass parts with a soft, dry cloth to keep them looking shiny. Be careful not to use abrasive cleaners as they may damage the finish. Also, because it has a Prop 65 warning due to Di(2 - ethylhexyl)phthalate (DEHP), avoid prolonged contact with the lamp's surface. If you have any children or pets, keep an eye on them around the lamp. And remember, even though it's UL certified, always follow basic electrical safety rules.
