Using your Brentwood Mid Century Steel Marble Table Lamp is easy. First, assemble the lamp following the instructions provided, as adult assembly is required. Once assembled, find a stable spot like your desk or bedside. Since the bulb is sold separately, make sure to get a 60 - Watt A19 incandescent bulb and screw it in. Use the in - line rotary switch to turn the light on and off. You can adjust the brightness if you have a compatible dimmer. The lamp can swivel, so you can direct the light where you need it. When it comes to maintenance, clean the lamp regularly with warm water, mild soap, and a soft towel. Avoid using harsh chemicals as they may damage the painted finish or the faux woodgrain shade. Keep in mind that the lamp isn't stackable and isn't height - adjustable, so handle it with care to prevent any damage.
