Solar Sensor Wall Lights & Garden Lights
A solar lamp also known as solar light or solar lantern, is a lighting system composed of an LED ... to surroundings, and further losses are of approximately 15-20%. Only 23% is absorbed which means a battery is a crucial part of solar lamp.
A solar cell can charge a battery from natural sunlight or from artificial lighting like an incandescent light bulb. A solar cell responds in much the same way to either kind of light; you can use incandescent light with a solar cell to charge a watch or calculator battery, provided the light is bright enough.
LEDs produce most of the wavelengths as well, but in different proportions. So, from a scientific standpoint, LEDs will probably produce the correct light to charge a solar cell.
