Using your Helene Rechargeable LED Table Lamp is a breeze. First, you'll need to assemble it as assembly is required. Once it's set up, you can recharge it using the built - in USB port. It takes about 3.5 hours to fully recharge. When you want to turn on the lamp, just use the touch - sensor dimmer switch. You can adjust the brightness to your liking. It can stay on for 7 hours at maximum brightness. Remember, the lamp emits a downlight, so it's great for creating a cozy atmosphere. When it's time to clean, always disconnect the power first. Then, use a soft, dry cloth to wipe it. Don't use chemicals or household cleaners because they might damage the lamp's finish. Also, be aware that the lamp contains DEHP and lead, which can cause cancer, and have developmental and reproductive health risks according to Prop 65.
