SureFire's Kroma MilSpec features a dual-output primary white LED with a maximum output of 50 lumens and single-output secondary LEDs in four colors useful in military applications: red, blue, yellow-green (all low-signature colors that help preserve night-adapted vision), and infrared (to be used in conjunction with night-vision equipment). The Kroma is compact, 5.5 inches, and lightweight, 5.1 ounces, making it easy to carry. Its secondary colored LEDs will run for 24 hours on a single set of batteries; its primary white LED for 1.5 hours on its "high" setting.
