Using this pendant light is simple. First, make sure to have a licensed electrician install it as per the instructions in the box. Once installed, you can screw in your preferred E14 bulbs (not included) up to a maximum of 60W each. This light is for indoor use only, so don't place it outdoors. To maintain it, gently wipe the stainless - steel body with a soft, dry cloth. Avoid using abrasive cleaners as they may scratch the surface. If you encounter any issues within a year, you're covered by the replacement warranty.
