A standard photocontrol can be triggered by an artificial light at night, fooling it into thinking it is daylight and turning off a streetlight or floodlight. The area is left in darkness and in danger. Any thief or vandal with a flashlight or laser pointer can disable a perimeter light long enough to gain entry and perform illegal activity.

The LIGHT KEEPER II is the solution.
The LIGHT KEEPER II is designed to protect streetlights and floodlights from artificial light from the ground causing unwanted operation, keeping secure areas well-lit. The LIGHT KEEPER II replaces standard twist lock photocontrols.

DESCRIPTION:
