Did you ever consider placing an outdoor chandelier in a sun room or solarium? Sunrooms can have a lot of extra humidity and dampness, especially when there are a lot of plants or a hot tub. Having an outdoor chandelier that is designed for damp/wet locations can extend the life of your fixture. Typically chandeliers rated for outside use have sealed circuitry, to prevent moisture from penetrating into the light.

Also, whether you choose an indoor or outdoor chandelier, you might consider putting weather resistant shades on them regardless of the type fixture.  I have even seen some shades that were made from different metals.

Of course head clearance is always a consideration with a hanging fixture. Conveniently locating it over a table is one way to still incorporate your chandelier without bumping into it.  Or a higher clearance chandelier can be used in many more locations.

Outdoor chandeliers are designed for outdoor use, but if you want to extend your inside space with a covered porch or sun room, a chandelier rated for out-of-doors use is a wise decision.
