They can be used in any environment where artificial lighting is needed. These lights are great for camping, hiking, fishing, gardening, and other outdoor activities. The sun's energy is captured by photovoltaic (PV) cells. When these cells absorb sunlight, they release electrons. A wire connects each PV cell to a battery. As long as the sun shines, the batteries continue to power the lights.
