The light goes on automatically at dusk and switches off during the day. No wiring or switching is required, which can make these energy-independent fixtures very cost effective in some applications. Plus, they use no utility-company electricity. One drawback is that solar fixtures generally use fairly small lamps that don't throw much light.
