Using these ALTA wall lights is easy. First, find a suitable indoor spot for them. Remember, you'll need to have a licensed electrician install them as per the instructions in the box. Once installed, screw in an E27 bulb (max 72W) that you've bought separately. You can adjust the lamp head to point the light where you need it. For maintenance, just use a soft, dry cloth to clean the iron and copper parts regularly. Avoid using harsh chemicals as they might damage the finish. If anything goes wrong within the first year, you're covered by the replacement warranty.
