I own two Phantom Warrior lights. One was specially modified by them for me on request. The normal one has an IR LED, one cobalt blue LED and a white LED. When you first turn on the switch, the blue LED comes on. This is used by medical personnel to check for damaged corneas and eye damage. As you turn the dimmer switch up higher, the white LED comes on, providing you with a useful light for map reading in color correct white light. Some map colors wash out in red or green filtered light. If you reverse the batteries, the IR LED is active and useful for conditions where a white LED would be hazardous to be seen (i.e. near enemy positions). The lights are well made, but the white LED output isn't very powerful. That's ok, because the lights are designed for military use where tactically you don't need that much light. There is little to no visible or IR light flare due to the design of the flashlight. This prevents enemies with night vision equipment from detecting you.
There are different variations of the Phantom Warrior flashlight available. One model is designed for pilots with ANVIS night vision goggles. The PW light is widely used throughout the military and can be ordered via National Stock Number through the supply system.
Victoria McDermott is the director of military sales and limits the sales to government and military organizations and personnel. Let me know if you are interested in more info than the site provides. I've got some of their sales brochures and flashlight operator's manual.
