Using this Addison Adjustable Pharmacy Desk Lamp is a breeze. First, find a stable spot for it on your desk or any flat surface. Since the lamp has two easy adjustment points, you can bend and position the arms to direct the light exactly where you need it, whether it's for reading, working, or just adding some ambiance. When it comes to bulbs, you'll need to buy a 75W medium - base incandescent bulb and screw it into the socket. Make sure the lamp is unplugged before you change the bulb. For safety, don't touch the bulb when it's on or right after you turn it off, as it can get very hot. To keep your lamp looking great, use a soft, dry cloth to wipe it down regularly. Avoid using harsh chemicals or abrasive materials, as they can damage the antique brass finish. Also, keep in mind that this lamp is subject to California's Prop 65 warning about lead exposure, so handle it with care.
