What style? There are lots of great out door chandys.

Are you interested in one that is wired for electricity or intended for candles? The latter can simply hang from a hook on a porch or gazebo.

Search for "outdoor wrought iron chandelier" instead. That will give you links to search. Here is one I found http://chandeliersten.com/outdoor-wrought-iron-chandelier/. Frontgate has outdoor chandeliers that are very expensive but gorgeous. Homedepot has some very inexpensive options. You can also try directlighting.com. Take a look at the Kichler brand. There are plenty to find, just depends on your taste. Hope that helps

This one you can use on an outdoor covered porch. Don't know if that is enough?
