Using your Scatchard table lamp is easy. Just plug it into a 120 - volt outlet. Then, screw in a 150W 3 - way medium base incandescent bulb. The switch on the socket makes it simple to turn the lamp on and off. When using the lamp, keep it on a stable surface to avoid it tipping over. Since the bulb can get hot, don't touch it when it's on or right after turning it off. To clean the lamp, use a soft, dry cloth to wipe the ceramic base and the linen shade. For the base, if there are stubborn stains, you can use a mild soap solution. But always make sure it's completely dry before using the lamp again. Remember, this lamp is compliant with CA Title 20 when shipped with an LED bulb. And be aware that it may expose you to lead, so keep it out of reach of children and follow the guidelines on www.P65Warnings.ca.gov.
