FLITELite NVIS Compatibility
MIL-STD-3009 was developed by the Department of Defense in February 2001 and superceeded MIL-L-85762A. It specifies that NVIS White for crew cockpit and utility lighting. NVIS Green A is grand fathered into the cockpit for certain applications, but not for new applications.
The chromacity of NVIS White makes it a full spectrum light even though is appears to have a green tint. Visible light can be split into the three primary colors, red, green and blue. The eye needs two primary colors to see 'white'. NVIS White, in simple terms is blue range through the green range. NVIS goggles filters allow a thin band of green light though the lens - so that users can see heads up displays and and other required applications through the goggles.
The level of light with respect to the chromacity is important due to this leak (filter) in the goggles. Other manufacturers claim to be the 'only authorized' lights produced since they meet a request for proposal standard. These claims are false - they have never tested FLITELite products how could they know? FLITELite meets and exceeds non-binding RFP standards, AND meets the modern, more stringent MIL-STD-3009, which is a binding requirement specified by the military.
General Aviation pilots can benefit from this technology. This light spectrum and intensity is perfect for general night vision use as well.
FLITELite minimizes the crossover zone by using a special combination of LED's and Filter material. The filter material ensures that the light greater than 600 nm is not transmitted.
