Using the Yani Table Lamp is a breeze. Just plug in the 60 - inch cord and you're ready to illuminate your space. When it comes to safety, remember this lamp is UL - certified, so you can trust it. But take note that it has DEHP and LEAD, which can cause cancer, developmental, and reproductive problems as per Prop 65. For maintenance, before you clean the lamp shade or the fixture, always turn off the power and unplug it. Then, gently wipe it with a soft, dry cloth. Don't use any chemicals or household cleaners because they can ruin the look of the lamp. And if you ever need to replace the bulb, the included one has a size of 55x55x110mm.
