I am concerned about rusting, how will these fixtures hold up?

All of our light fixtures are constructed of Heavy gauge solid brass sheet metal and will not rust.

Are your light fixtures adaptable to low voltage?

Yes. There are 12v medium base light bulbs that look just like standard 120v but you may only find them in lighting showrooms, electrical supply stores, recreational vehicle and marine stores. There is no modification needed to the light fixture.

Which finishes do you recommend for landscape - garden lighting?

Our top selling finish is Verde with Gold iridescent glass and will blend into your landscape nicely.
