Light Level Measurements

Light level sensors are used by DDC control systems for lighting control. They are typically used to turn on night lighting when light level drops below a set level and are also used to turn off indoor and outdoor lighting when ambient levels are sufficient. Light level sensors can be used to control the output of dimmable fluorescent lighting to set levels. Accuracy of ±1% of reading is common.
