I want to know how it works,and the benefits of using solar lights.
Solar power lights are recharged by the sun each day. If there are several days of cloudy weather the lights will not charge sufficiently to give light. Eventually the solar cell inside wears out and must be replaced, good luck on finding replacements.
Conventional lights need electric lines to them Years ago the only type were the 110 lines, like in your house. Some decades back 12 volt systems became available. You plug a transformer into an outside outlet and then run your wires wherever you want light. Unlike the 110 volt systems that require conduit (pipes) around the wire, 12 volt lines can be run on the ground or buried , your choice. Attaching lights is extremely easy. You get more light choices, different types of bulbs so you can have pinpoint light to wall washing, build into steps and stair, hung in trees, rafters of houses…..wherever you want light. The 12 volt are a DIY dream. The number of lights is determined by the transformer size.
solar lights, yeah they are fun, but I never found they put out that much light.
