Description:
This is a very small photocell. A photocell changes (also called a photodetector, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).

Features:

• Five (5) Photocells included
• Light resistance : ~1k Ohm
• Dark resistance : > 10k Ohm
• Max voltage : 150V
• Max power: 100mW
• 2 x 4 x 5mm
• 4mm between pins
• 35mm lead length
• Good price!
