Using this pendant light is simple. First, have a licensed electrician install it according to the instructions in the box. Since it's for indoor use only, don't place it outside. The lamp holder can take a bulb up to 72W, but you'll need to buy the globe separately. For maintenance, use a soft, dry cloth to clean the powder - coated aluminium shade. If there are any issues within a year, you can get a replacement as per the warranty.
