Using your Rydler outdoor pendant light is easy. Just turn the ON/OFF switch to light it up. The pendant comes with C35, E12 bulbs, so you're ready to go right away. Place it on your porch or verandah to enjoy the warm and pleasant illumination. When it comes to maintenance, simply wipe the clear glass panes and black metal finish with a soft, dry cloth to keep it looking great. Avoid using harsh chemicals as they might damage the finish. Also, make sure to replace the bulbs when they burn out. The max wattage is 40W, so don't use bulbs with a higher wattage to prevent any safety issues. Since it's from China and doesn't require assembly, you can start using it right after unpacking. But be aware that it has P65 toxicity/health warnings related to cancer, developmental, and reproductive concerns, so handle it with care.
