Using your MASON modern retro tipped glass pendant light is easy. First, make sure you have a 1xE27 bulb (up to 60W) as the globe isn't included. Have a licensed electrician install it following the instructions in the box. This light is only for indoor use. When it comes to maintenance, gently wipe the glass and iron parts with a soft, dry cloth. If you encounter any issues within the 1 - year warranty period, you can get a replacement. Just be careful not to confuse it with low - quality similar products from other suppliers.
