Using the Access Lighting Rockaway Outdoor Dual - Voltage LED Flush Mount is easy. First, make sure your electrical system voltage is within the 100 - 277v range. Find a suitable ceiling spot outdoors and mount the light according to the instructions. The lamp is already included, so you don't need to buy one separately. When using it, keep in mind that it's not ADA compliant and not for emergency lighting. Since it has a wet location rating, it can withstand outdoor weather, but avoid direct physical impact. For maintenance, clean the glass shade with a soft, damp cloth regularly to keep the light bright. The aluminum fixture is durable, but if you notice any signs of corrosion, especially in a marine environment, you can gently wipe it with a mild cleaner. Overall, this light is a great addition to your outdoor space that will last a long time with proper care.
