There are several types of outdoor area lights perfectly suited for residential use:
For illuminating larger commercial spaces, shoebox area lights are a great option. With up to 300W, Globalux shoebox area lights are an excellent choice for parking lots, large driveways and expansive yards.
Microwave sensors operate by measuring the time it takes for microwave signals to bounce back to the sensor. When a person or object moves through the area, it alters the length of time it takes for the signal to return. The lengthening of time triggers the lights to turn on, providing illumination exactly when and where it is needed. Microwave sensors are commonly used with security lights because of their ability to provide motion triggered lighting.
Photocells are equipped with semiconductors that respond to changes in light levels. This allows electricity to flow more efficiently as the light level increases. Because of this, photocells are commonly used as dusk to dawn sensors in LED light fixtures.
