A lighting assembly topology that utilizes spectrum controlling materials to render the illumination compatible with night vision imaging systems. The lighting assembly can be used as either a general illumination source or can be used as a backlight for a transmissive display such as a liquid crystal display. The lighting assembly makes use of spectral filtering which is both transmissive and absorptive for specific spectral regions. The exit port of the lighting assembly is completely filtered with a red and near infrared reflective filter. The absorption of the near infrared spectrum to which NVIS are sensitive is reflected by the typical near infrared reflective filter covering the exit port and absorbed within the material lining the housing of the lighting assembly.
