Using this Access Lighting LED wall - mount is easy. First, make sure you have the right voltage in your outdoor area (it works with 120 - 277v). Mount it on the wall following the instructions provided. The lamp is already included, so you don't have to worry about getting one separately. During normal operation, it will give you bright, warm light (3000K color temperature) with good color rendering (CRI of 90). In case of a power outage, the emergency backup feature will kick in automatically to keep your area lit. For maintenance, you can clean the acrylic shade with a soft, damp cloth. Avoid using harsh chemicals as they might damage the fixture. Check the fixture regularly for any signs of wear, especially if it's in a wet or marine environment. Also, make sure the mounting is secure at all times.
