Using your Penta Table Lamp is easy. First, find a suitable spot in your room, making sure the 6 - foot cord can reach an outlet. Since bulbs aren't included, you'll need to buy a bulb with a maximum wattage of 150W. The 3 - way switch allows you to adjust the brightness. To turn it on, simply flip the switch. When it comes to maintenance, use a soft, dry cloth to gently wipe the Dutch blue porcelain base and the white linen shade. Avoid using harsh chemicals as they may damage the finish of the base or the fabric of the shade. And because it's UL/ETL approved, you can be confident in its safety. Just keep in mind that the plug isn't polarized, so make sure to insert it correctly into the outlet.
