Pros & Cons:  Pros:  Unique and beautiful, especially for an outdoor-rated fixture, flexibility with battery or plug-in.  Cons:  The length of the chain/cord isn't adjustable, the bulb isn't replaceable (but should last for a long time), and you need to have a solid ceiling to affix it to, to protect the battery compartment (which is in the canopy that gets attached to the ceiling), whether or not you use the battery option.  I was planning to hang it inside a pergola, but that won't work because the beam is too narrow and wouldn't cover the full diameter of the canopy, and you have to use the canopy.  Will try to make it work by installing a cross-piece of wood to attach the canopy to.
