Dark Sky Friendly Devices

Dark sky friendly technologies are systems that aid in the mitigation of light pollution.


The Device Seal of Approval was created to recognize a wide range of technologies that help curtail unnecessary light emissions.

Approved Devices

  • Obstacle Collision Avoidance System (OCAS inc.)
    The OCAS solution is an on-demand obstruction warning system using advanced 3D radar technology and standard obstruction lighting. OCAS provides both visual and audible (optional) warnings to pilots on a potential unsafe heading toward the aviation obstacle (such as wind turbines, overhead power lines and towers). OCAS improves the environmental profile of these obstacles by eliminating light pollution caused by unnecessary lighting.
  • Scallop Imaging
    Scallop Imaging provides businesses, individuals and the military with a range of high-resolution camera technologies that dramatically improve visual capabilities without the assistance of artificial lighting or IR emitters.
  • The Flagpole Beacon
    The Flagpole Beacon is the most environmentally correct way to illuminate flags during night hours. For the first time, flags can be properly lit during nighttime hours without lighting adjoining property and the night sky.
