Using your Mercer 4-Light Pendant is simple. First, have a professional install it as the product requires professional installation. Make sure to use four E26 bulbs with a maximum of 60W or their LED equivalent (bulbs aren't included). This light is great for areas like the bathroom as it's ETL listed for damp locations. You can adjust the height of the hanging rods to fit your ceiling. Keep in mind to clean the fabric cone shades gently with a soft cloth. If you notice any issues, contact a professional for maintenance. Enjoy the modern and stylish illumination it brings to your space.
