Using your Blomus Farol Rechargeable Mobile LED Floor Lamp is a breeze. To turn it on or off and adjust the brightness, just give the center of the lampshade a gentle touch. You'll have three levels of brightness to choose from, so you can set the perfect mood. When it's time to charge, simply plug it in using the USB plug. The charging time and how long the lamp runs depend on the brightness level you've set. It can last anywhere from 8 to 40 hours. As for maintenance, keep the lamp clean by gently wiping it with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Also, make sure to place the lamp on a stable surface to prevent it from tipping over. If you're not satisfied with your purchase, don't worry. It's covered by our 30 - day return policy.
