Using this LED night light is easy. Just connect the USB interface to a power source, and the light will turn on. It's great for adding a warm glow to your room. When it comes to cleaning, gently wipe the acrylic light panel with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials as they may damage the surface. Be careful not to pull on the USB cable too hard to prevent it from getting loose. If you notice any issues, contact us for help. Also, remember that the actual color might look a bit different from the picture because of your monitor and the lighting in your room, and the size could have a small difference due to manual measurement.
