Wall pack lights with photocells or motion sensors are designed to enhance energy efficiency and convenience by automating lighting based on environmental conditions or movement. Photocells are light-sensitive sensors that detect ambient light levels. They are typically used to turn lights on at dusk and off at dawn. The photocell contains a semiconductor that changes its electrical resistance based on the amount of light it receives. When it gets dark, the resistance decreases, allowing current to flow and the light to turn on. Conversely, when it becomes light, the resistance increases, cutting off the current and turning the light off. Motion sensors, on the other hand, detect movement within a specific range. They use technologies such as passive infrared (PIR), microwave, or ultrasonic sensors. PIR sensors detect the infrared radiation emitted by moving objects, such as humans or animals. When motion is detected, the sensor sends a signal to the light to turn on. After a preset period of no motion detection, the light automatically turns off, conserving energy. Some wall pack lights combine both photocells and motion sensors for optimal performance. In such systems, the photocell ensures the light only operates during low-light conditions, while the motion sensor activates the light when movement is detected. This dual functionality maximizes energy savings by ensuring the light is only on when necessary. These systems are particularly useful for outdoor lighting applications, such as in parking lots, building perimeters, and pathways, providing security and visibility while minimizing energy consumption.
