What Does NVG Friendly Mean?

Both the FAA and Transport Canada have issued safety alerts warning that common LED obstruction lights pose a hazard to pilots using Night Vision Goggles (NVGs). This is due to the fact that NVGs typically use filters to block cockpit lighting from saturating the imaging system. This has the unintended effect of making LED obstruction lights invisible to pilots.

In response, we have incorporated NVG Friendly technology into our fixture (IR 850nm peak intensity), giving pilots using night vision goggles unmatched visibility of airfield perimeters, buildings, and towers. The L810LEDNV light is the first LED L-810 available to ensure that your structure is visible to all pilots, making it the first true LED replacement for incandescent obstruction lights.

Obstruction Lighting Controls

Lighting controls are designed for use when multiple obstruction light fixtures are to be controlled with common electronics. The electronic control module comes in a cast iron device box with threaded hubs on both top and bottom. Replacement modules (controls without device box) are also available upon request.

Obstruction Light Controller Model 81020


Model 81020: 120/208/240/277VAC, 1000W photocell. FAA style photocells activate at 35 ft-cd and turn off at 58 ft-cd. A 45 second time delay prevents activation and de-activation from momentary light conditions. Does not come with device box, includes 1/2″ threaded male fitting.

Obstruction Light Controller Model 81021
Model 81021: 120/240VAC, 4800W photocell. Meets FAA/FCC requirements for obstruction lighting. Energized at 35 ft-cd and de-energized at 60 ft-cd. Time delay eliminates contact chatter. Contains dual 20A load contacts. Front plastic housing mounts to cast aluminum junction box (included).

Obstruction Light Controller Model 81022
Model 81022: Hazardous Location Photocontrol Unit. Outdoor lighting control for exterior lighting in hazardous locations: explosion proof, dust-ignition proof, and weatherproof. Nominal Voltage 50/60 Hz: 120/208/240/277VAC. Voltage Range: 105-305. Housing: sand cast copper-free aluminum – epoxy powder coated.
