Photocells
Photocells are circuit elements used in automatic control systems for lighting. These enable a light to turn on when the surrounding environment is dark and turn off when it becomes bright again. The photocells in the lights tell the circuit when to provide more or less current, thus turning the light on or off as needed. Photocells are very useful in a variety of applications, such as in our LED Dusk To Dawn Lights.
