We needed a bit more light shed on entryway step. We already have low-voltage lighting along the walks. Two of these little lights did the trick and we simply tied them in to the existing low-voltage system. Fitting the cover onto the lighting assembly is a little futzy but we finally figured it out. Don't be intimidated by low-voltage lighting (and don't waste your money on solar systems unless you live in a VERY sunny area -- you'll be disappointed by the lack of real light). Plenty of good how-to about installing systems easily and safely.
