Many homeowners use outdoor lighting as part of their landscape decoration and for security. To save money, it's best to shop for lights that need a motion detector. If you're trying to illuminate a pathway, then buy low-voltage lighting. If you really want to save some cash, install CFLs and LED lights. They are very durable and perform well in cold climates [source: EnergySavers.gov].
Installing solar powered lights is also a good way to save some cash. The lights use sunlight for power and charge during the day. Since they don't require wiring, the lights can go anywhere on your property. Some solar powered lights also come with motion detectors.
