Led flashlight for Night Vision: Pentagon S2 Red Light
There is nothing more disconcerting than having to disturb the 'enviroment' during night-time observation with the beam of a flashlight to check on data or equipment. The 'soft' white light of led flashlights have gone some way in appeasing this situation but the recent entry of the Pentagon S2 Red Light should satisfy the needs of the night sky viewer. 'Red light is a low-signature light, which ensures stealth in the darkness. It is also a necessity for any pilots, vehicle operators, and other specialists who need to preserve night vision when reading charts, maps, and going over checklists. The use of a red filter over the beam of a conventional flashlight creates a narrowly focused hot spot that overly affects night vision and projects excessive red light into distance, thus compromising stealth. The advantage of S2 Red is in its effective light diffusion, which provides a wide area coverage of red light with excellent close range light intensity.'
