Too much artificial light at night is linked to a number of environmental issues.
Plants and animals rely on the natural rhythm of day and night to help control their reproduction, sleep, and migratory patterns as well as for protection from predators. Urban light pollution from outdoor sources like parking lots and roadways as well as residences and office buildings interferes with these vital biological activities. Leaving the lights on also increases carbon emissions. In the United States, about 15 million tons of carbon are emitted annually to power outdoor residential lighting alone.
Installing motion sensor lighting at home saves money and energy, and helps solve some of the issues associated with keeping the lights on all the time. They’re also a low-cost option for deterring trespassers. Select a model that offers the appropriate type of light that adequately covers the square footage (typically 75 to 100 square feet) you want to brighten, like walkways to your front and back door, driveways, patios, decks, or hazardous locations like swimming pools and staircases.
Here are some of the best models of outdoor sensor lights:
