Using the Niara Rechargeable LED Table Lamp is a breeze. First, you'll need to assemble it as assembly is required. Once assembled, use the built - in USB port to charge the lamp for about 3.5 hours. When it's fully charged, it can last up to 7 hours at maximum brightness. To adjust the light, just use the touch - sensor dimmer. As for the light direction, it shines downwards. When it comes to safety, be aware that the lamp contains DEHP and lead, which may cause cancer, developmental, and reproductive issues. For maintenance, always remember to disconnect the power before cleaning. Wipe the lamp with a soft, dry cloth. Never use chemicals or household cleaners because they can damage the finish.
