Using your Verdell table lamp is a breeze. Just plug it into a 110 - voltage outlet and switch it on using the 3 - way socket. The lamp comes with a single type A bulb, and you can replace it with another 150W type A bulb when needed. To keep it looking its best, dust the ceramic base and linen shade regularly with a soft, dry cloth. Avoid using abrasive cleaners on the ceramic or the brass accents as they can scratch the finish. And remember, this lamp contains nickel, so handle it with care. If you have any concerns about the chemicals, check out www.P65Warnings.ca.gov/furniture for more details.
