Using your Nolen table lamp is easy. Just plug it into a standard electrical outlet using the 2 - prong polarized plug. Then, use the inline rocker switch to turn the lamp on and off. The lamp has 9 bulbs, so it provides plenty of light for your space. When it comes to maintenance, make sure to turn off the lamp and unplug it before cleaning. You can use a soft, dry cloth to wipe the metal frame. Avoid using harsh chemicals as they may damage the black metal finish. Also, be aware that the lamp has a Prop 65 warning because of Di(2 - ethylhexyl)phthalate (DEHP), so handle it with care. If you need to replace the bulbs, use E12 or Type B bulbs with a maximum wattage of 25.
