LOC LED dusk to dawn light fixture with selectable power used in agricultural buildings, outdoor security, and other large areas. It's energy-efficient only uses 30 to 65 watts of electricity and has a prismatic lens which disperses light evenly. It's UL listed for wet locations and it's made for a harsh environment, made to stand up to what the weather conditions are outside. It can start even in the coldest of winters and give off the same amount of light as warmer conditions. It can be mounted on the side of a building or almost anywhere you have a flat surface and a reasonable amount of space. This is probably one of the most efficient LED lighting fixtures for many people who have large areas to light. This is particularly the case for farms and the agricultural regions where a single lighting fixture will provide enough light to keep an area secure.
