The lamps are connected/disconnected automatically to detect a level of determined brightness (they are turned on at night and turned off during the day).

Benefits

  • Ability to designate lighting zones

  • Lower maintenance

Limitations

  • More complicated lighting schematics & installation

  • Longer installation

  • Products require initial calibration

  • May not work properly if installed in an improper location

Economic assessment
