Kroma: The Worlds most Technologically Advanced Flashlight
Who needs a flashlight that produces three seperate colours of high quality LED light, each with dual output levels? The better question is, who wants a high-tech illumination tool that does the work of six seperate flashlights, fits in your pocket, endures abuse from Mother Nature and insensitive owners, and weighs in at barely over 5 ounces?
You can put your hand down now.
The state of the art Kroma was developed as part of a collaborative project for DARPA (Defence Advanced Research Projects Agency) to supply US forces with high-performance flashlights in the field. The Kroma's main LED throws out enough TIR lens-focused white light to temporarily blind or disable the night-adapted vision of a foe. Its red and blue secondary LEDs are perfect for preserving the night-adapted vision during tasks requiring minimal light, such as reading maps, tracking or navigating trails - without disturbing wildlife if you use red (many wild animals cant see light in the red portion of the spectrum). But no matter what the task, if you decide its time for a different color or a higher or lower output level, just twist the no-look selector ring or press down on the tailcap to instantly change your perspective.
So who needs a Kroma? Only those who want one of finest, most versatile pieces of handheld technology in the world.
What goes into a Surefire LED Torch
There is a lot of buzz about light emitting diodes (LEDs) and for a good reason. LEDs allow runtimes that were previously unattainable on a single set of batteries. When it comes to longevity, they are in a class by themselves, the thousands-of-hours class. That is because they are a solid state device, no filament to burn out or break, no gas or liquid components, no glass to break. Just a semiconductor chip that converts electrical energy into light, which it disperses through a tough, clear polymer covering.
LED output levels are approaching, even surpassing in some cases, those of incandescents. But for raw lighting power, Surefire’s three, four and six battery incandescents are still the way to go. However, and incandescent lamp becomes particularly useless if the power level drops below the amount of energy required to make its filament glow white hot. An LED, on the other hand, continues to function at power levels below its maximum output level. Which means an LED will continue to run – albeit at lower and lower output levels. So you get more useful light for a longer period of time with an LED flashlight than with an incandescent.
Not all LEDs are created equal. They can vary greatly in quality, even supposedly identical LEDs made at the same facility. Surefire uses only the finest, highest quality LEDs in its illumination tools. They are electronically controlled for maximum efficiency, focused by a reflector or Total Internal Reflection lens for a perfect beam, and housed in a rugged, weatherproof, knurled aerospace grade aluminium body that keeps the elements out and your flashlight in hand.
