Using the Decor Walther 120 N LED Wall Light is easy. First, make sure the power is off before installation. Mount it on the wall according to the provided instructions. Once installed, turn the power on. You can adjust the brightness if you have a compatible phase - cutting dimmer. For best results, keep the wall light in a dry place as it has an IP 44 protection class, but avoid direct contact with water. To clean it, use a soft, dry cloth to wipe the durable acrylic glass shade. Don't use harsh chemicals as they may damage the fixture. With a long lifespan of up to 80,000 hours, you won't need to replace it often. But if you do need to change the bulb, it's included with the fixture. Enjoy the warm, inviting glow this wall light brings to your space.
