Using the Carwen outdoor pendant light is a breeze. Just find a suitable spot on your porch or veranda, and since no assembly is required, you can hang it right away. Use the ON/OFF switch to control the light easily. When it comes to bulbs, it comes with an A19 bulb with an E26 base, and you can replace it with another bulb as long as it doesn't exceed the 60W max wattage. As for maintenance, wipe the steel and glass parts regularly with a soft, dry cloth to keep it looking good. Because of its P65 toxicity information related to cancer, developmental, and reproductive health, be careful not to break the lamp and avoid any direct contact with internal components. Also, make sure the hanging area is stable to prevent the light from falling.
