Our outdoor lighting fixtures were a mixed bag of rusty, faded brass...
I didn't have budget to buy all new fixtures (those things ain't cheap!) so I decided to work with what I have. The only thing I needed to do was purchase was a can of spray paint (Rust-Oleum's Oil Rubbed Bronze), turn off the breakers (so I wouldn't get electrocuted), and get to work!.
The immediate before and after was awesome!
Here they are after I reinstalled them.
