Surefire Kroma MilSpec Dual-Output Multi-Spectrum LED Flashlight
The Kroma MilSpec has a Luxeon III LED emitter and a TIR (Total Internal Reflection) lens to produce brilliant high-white output with a spot beam of 130 lumens, which is about eight times brighter than your typical D battery light. The use of the TIR lens provides a concentrated hotspot with excellent throw distance while still affording enough surround light for clear peripheral vision in the dark. You also have a low output setting that brings the brightness levels down to just four lumens and extends your battery life to about 20 hours of runtime. Your secondary LED's offer low-output flood beams in blue, red, yellow/green and an infrared setting for use with night-vision goggles. Simply twist the unit's selector ring to switch between high and low output, and white or color output, plus it's been designed for use in the dark so you don't even need to see it to make your setting choices. The Kroma MilSpec has also been built for exceptional durability; made of aerospace grade aluminum with a coated and tempered lens window which has been designed to be darn near indestructible while maximizing your light output. It's also been weatherproofed at the O-ring and gasket so you won't have to worry about water getting inside and damaging the unit. The Kroma MilSpec runs on C123A lithium batteries which are included in the packaging, so just stick them in and you're ready for anything.
