Photocell box complete bureaucracy indoors

Sorry about the mess of the room and the quality of the video, I took the video using my Motorola mobile. This is the photocell box controlling the desk lamp at the PC, bedside table lamp and the fluorescent lamp. Notice that when the photocell gets covered, it turns on straight away, however when it's light enough, there's a minute delay before it actually switches off. This is a popular feature in many photocells. It prevents headlamps at night, lightning strikes and random torchlight flashes from accidentally turning off the photocell.
