Using this pendant light is easy. First, make sure to get it installed by a licensed electrician as per the instructions in the box. The lamp holder takes a 1xE27 bulb (not included), so you can choose the bulb that suits your lighting needs. Since it's for indoor use only, don't place it outside. For maintenance, you can gently clean the powder-coated aluminium body with a soft, dry cloth. Avoid using harsh chemicals as they may damage the finish. The gold dimpled interior should also be cleaned carefully. If you have any issues within the 1-year warranty period, you can get a replacement.
