Dusk to dawn lights utilise a photocell sensor some times called a CDS cell or photoresistor. Generally resistance increases as the light levels drop. This feature is particularly useful for security and safety purposes where it is important to maintain specific light levels and can be activated automatically when these light levels are reached.
