Using the Access Lighting Adapt Outdoor Adjustable LED Wall Mount is easy. First, find a suitable outdoor wall location. Make sure the electrical system in that area operates within the 120 - 277V voltage range that this fixture requires. Mount the backplate/canopy on the wall according to the provided dimensions. Then, attach the wall mount to the backplate. You can adjust the extension from 3 to 8 inches to get the perfect lighting angle for your needs. When it comes to maintenance, since it has a wet rating, it can handle various weather conditions. But it's a good idea to clean the glass shade regularly with a soft, damp cloth to keep it looking good. If you notice any issues with the brightness or if the lamp stops working, check the electrical connection first. If the problem persists, it might be time to replace the 30W LED lamp. And always follow local electrical codes and safety guidelines when installing or working on this lighting fixture.
