Solar lighting is the safest and easiest kind of outdoor lighting to install. It provides sufficient light for entrances, walkways, steps, or to indicate the location of dark obstacles. Each light fixture features a solar collector panel that converts sunlight into electrical energy. This energy is stored in rechargeable batteries used to illuminate the fixture at night. Made from bamboo. The batteries recharge in direct sunlight and should not have to be replaced for at least three years. Most solar products use LED (Light Emitting Diodes) as a light source because of their low power consumption and long life. LEDs are not replaceable, but their life expectancy typically exceeds 25 years, running 10 hours every night.
