Using your Olen flush mount light fixture is easy. First, since assembly is required, carefully follow the included instructions to put it together. Once assembled, find a suitable spot on your ceiling and install it. You don't need to worry about a switch mechanism, as it's designed without one. The S14 LED bulbs are already included, and they have a max wattage of 40 and a power of 4 watts. When it comes to safety, the fixture is UL - certified, but be aware that it contains DEHP and lead as per Prop 65 regulations. As for maintenance, always remember to disconnect the power source before you start cleaning. Use a soft, dry cloth to wipe the lamp shade and fixture. Avoid using any chemicals or household cleaners because they can damage the finish. With proper care, your Olen light fixture will keep lighting up your space beautifully for a long time.
