What style of light? Wall mount? Post mount? How much area are you trying to cover?
Personally, I like and have installed TONS of these cheap wal-lites, they come complete with PC. Under $100 : WM Wal-Lite
They are available under many different brands at many retailers. HD carries them for one.
Have you considered LED. Prices are cropping fast while output is increasing. For a cheap running, very long lasting and maintenance free light they are the way of the future.
Yes, wall mount. Coverage, about 50 to 60 feet. mounted about 20 feet high. I haven't seen any LED yard lights at the big box stores. Only Low and High pressure sodium, fluorescent, and halide.
