The Green Spider is designed to work in conjunction with your present parking lot lighting controller (photo-cell, time clock or remote energy management system). It installs on any multiple fixture lighting pole in minutes.

Once installed, the Green Spider automatically allows all fixtures to operate normally during heavy traffic hours. At a predetermined interval, the Green Spider turns off up to three individual 1000 watt fixtures and leaves one remaining fixture illuminated for both code and security. At dawn, the Green Spider resets itself for the next day's lighting cycle.
