Using this wall light is easy. First, make sure to turn off the power before installation. Then, mount it on the wall in your hallway as per the instructions. You'll need to provide your own E14 bulb, with a maximum wattage of 40W. The lamp head can be adjusted to direct the light where you need it. Remember, this light cannot be dimmed. For maintenance, use a soft, dry cloth to clean the metal and plastic parts. Avoid using harsh chemicals. The cable is replaceable, so if it gets damaged, you can easily swap it out. Keep in mind that this light is for indoor use only and is not suitable for mounting directly into insulation.
