Using your Queren outdoor wall sconces is a breeze. First, find a suitable spot on your exterior wall, preferably near your entryway or in your backyard. Since no assembly is required, you can directly install the sconces on the wall. Just use the ON/OFF switch to turn the light on or off. When it comes to bulbs, the set comes with an A19 bulb with an E26 base, and the maximum wattage it can handle is 60W, but it currently runs at 9W with 805 lumens. Please note that this product has P65 toxicity/health warnings related to cancer, developmental, and reproductive issues, so handle it with care. To keep your sconces looking their best, clean them regularly with a soft, dry cloth. Avoid using harsh chemicals as they may damage the black metallic finish. Also, make sure to keep the glass shade clean for optimal light output. And that's it! Enjoy the charming glow these sconces bring to your outdoor space.
