The outdoor porch lamp is one of the most used light fixtures in any home, making it the perfect place to install highly efficient ENERGY STAR qualified lighting products. Many compact fluorescent light bulbs (CFLs) will fit easily into existing porch lights. Be sure to use bulbs approved for use outdoors.
ENERGY STAR qualified lighting fixtures are bright and warm but use about 75% less electricity than standard lighting and last up to 10 times longer.
Whether welcoming visitors, searching for your keys or ensuring safety, motion sensors are an electricity-saving option for lighting your way, because they only operate when they detect movement.
Consider photocell timers, which react to sunlight.
