Eco factor: Stepping stones with built-in solar panels create an illuminated path marker.
The Solar Powered Lighted Stepping Stone provides an elegant, inimitable and reasonable way to light up and revamp your garden or walkway. These stepping stones have a built-in solar panel that collects and converts sunlight into DC power and the built-in nickel-cadmium batteries store the energy to illuminate at night. These solar-powered lighted stepping stones have a built-in photo sensor that automatically turns the light on at evening and off at dawn.
It is made from a durable UV-protected poly-resin, which bears up to 250lbs. A 12.5-inch square stepping stone integrates four LEDs that generate bright light. Each long-life bulb is being said to last over 100,000 hours.
