Use solar outdoor lights
It's important for safety to keep doors and walkways well lit, and a brightened outdoor space may be a peaceful getaway spot or add aesthetic value to your home. Outdoor lights that stay on all night, however, can have you paying for electricity you don't need. Solar lights can significantly reduce outdoor lighting costs without compromising security or style.
How it works:
Solar lights use a connected panel to collect sunlight during the day. At night, a photocell (light sensor) turns the lights on, drawing from the stored solar power. Good to know:
Conventional lights are often brighter than their solar counterparts. If brightness is a concern, consider using a combination of conventional and solar lights in your yard.
What to look for: The most common solar lights are decorative garden lamps on stakes that drive into the ground. However, solar floodlights, post lamps and wall-mounted models are also available. Follow the manufacturer's recommendations for use during snow conditions.
Where to find them: Hardware stores and general retailers carry small solar lights. Some specialty lighting stores carry larger solar lamps or you can purchase them online.
