The Westinghouse Solar Steplights are solar powered and are perfect for illuminating stairs, walkways, docks and decks. Made to be mounted vertically or flat an integrated solar cell located on the top of each light recharges the included NiCd battery. Stainless steel construction is resistant to wear and corrosion. Bracket and screws are included for easy installation and no wiring required. These lights are great for safety on staircases and along the edges of deck or docks or creating a perimeter line along driveways. LEDs are more durable than conventional glass light bulbs and are more efficient. They use much less energy and will last a lot longer than a conventional light bulb. They are even more efficient than compact fluorescents.
