Using your Acrylic Desk Lamp is super easy. First, make sure it's charged by plugging the USB plug into a power source. Once charged, simply touch the sensor on the lamp to change the light color according to your mood. You can use it on your desk for reading, working or just creating a cozy atmosphere. When it comes to maintenance, keep it clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals as they might damage the acrylic material. Also, try to place it in a stable position to prevent any falls or bumps. If you notice the battery is running low, just plug it in again for a recharge.
