      Light dependent cadmium sulfide photoresistors housed in a compact small package. Photoresistors are also known as ligt dependent resistors (LDR), photoconductive cells or photocells.

      The photo-resistors are used as a low cost photo sensitive element in photographic light meters as well as in other applications such as smoke, flame and burglar detectors, card readers and lighting controls for street lamps.
