Using the Decor Walther RAY Wall Light is easy. Just mount it on the wall in your desired location, connect it to a power source within the 110 - 240V range, and it's ready to shine. As the bulb is already included, you don't have to worry about that. For safety, keep it away from water as its protection class is IP 20. When it comes to maintenance, simply wipe the glass shade gently with a soft, dry cloth from time to time to keep it looking clean. Since it has a long lifetime of up to 30,000 hours, you won't need to replace it often. Enjoy the warm and inviting light it brings to your space!
