Using your Graylyn outdoor wall sconces is a breeze. First, find a suitable spot on your exterior wall near the entryway or any area you want to illuminate. Since no assembly is required, you can directly mount the sconce on the wall using the round wallplate. Simply connect it to a power source and use the ON/OFF switch to control the light. When it comes to the light bulb, you have an A19 bulb included with an E26 base, and it has a maximum wattage of 60W, but currently runs at 9W with 805 lumens. As for maintenance, regularly wipe the steel body and shade with a dry cloth to keep the black finish looking great. Be aware that the product has P65 toxicity/health warnings related to cancer, developmental, and reproductive issues, so handle it with care. Also, make sure to install it in a dry outdoor area to prevent damage.
