1-Classification- The , P20 / M60L are medium sized handheld tactical flashlights.The P20 uses a 1W Luxeon LED emitter powered by 2XCR123A Lithium batteries and the M60L use a 5W Luxeon LED also powered by 2XCR123A Lithium batteries. These two lights are the cornerstones of the NightCutter line. They are both within the category of tactical lighting in that they have a momentary function and they use high flux or output emitters for a source of light. The M60L is furnished with a generous series of accessories that make it an especially excellent value as a package. Beyond their use as tactical lights- the unique metallic blue anodizing coupled with a 'Modernist/Machine Age" dimpled surface pattern push these products into the realm of flashlight as sculptural art. Moreover, their unique color makes them superb matches for the nautically inclined. In contrast to the land warrior Olive Drab or 'OD' color used for many military type lights, the NightCutter P20 & M60L are quintessentially the mariner's choice for matching the apparel of the ensign , admiral or recreational captain. They are in this respect, true to their flagship monikers.
2- Geometry- The lights are a radially symmetrical cylinder.
3- Build Quality- The P20 / M60Lare precision manufactured by CNC machine process. There is no threading roughness, and the quality of aluminum used is T6 Aircraft Duralumin type.
4- Physical Features - Both these lights look like they belong in a collection at the Museum of Modern Art . Rather than follow in lock step the leads of many other designers competing in this market space, the NightCutter designers have departed from the norm and have instead painted a daring stroke with their fascinating elongated lozenge shaped troughs . They are intermittently and circumferentially cut with a milling tool into the otherwise plain and smooth metal surface of the light. This design pattern not only gives the P20 and M60L a unique look, but it also substitutes large pattern gripability for the customary knurling so commonly found on other flashlights of this category. In most cases, such a strategy highly advantages users that may encounter very wet conditions or who may be using these lights with slippery hands.
5- Wall Thickness- The aluminum wall thickness of the battery tube is 2mm.
6- Finish- Anodized Type III Metallic (PMS 5405MC-Metallic) on the outside and throughout the inside. This anodizing should be effective against corrosion.
7-Fit- There is no 'play' or rattle anywhere in the P20 / M60L lights. Satisfactory 'O' ring seals at all junctions between sections provide, a snug fit and a seal against the elements- especially water. The front lens and reflector/optics are easily accessible by unscrewing the front bezel. Threading action is sufficiently smooth.

1-Controls- in normal use, light emits from the front of the flashlight when activation occurs through a either a partial pressing or a full clockwise turning of the dual function tail cap. There is no focus adjustment so this is the only control affordance that needs to be used.
2-Component/Section Accessibility The front bezel section is threaded to the body section, allowing for easy access to the enclosed LED module as well as allowing the use of optional modular optics and reflectors. In the case of the M60L additional bezels may also be attached instead of the standard one. The LED module is easily removable at the factory thanks to the use of two tiny allen screws ( Note: Lifetime Warranty may be voided if customers choose to perform repair, maintenance or upgrades to their lights). The optics or reflector and front lens may be removed and interchanged between the two lights. Bezels are not interchangeable however.
3 The removable tailpiece protects the battery compartment from the environment by a single 'O' ring and allows for battery replacement. Contact pressure is furnished by a coiled spring in the head rather than in the tailpiece. The tail caps and head have rubber gaskets as well as teflon rings to ensure that seals prevent water from entering. Though both these lights were tested as water resistant, they're not depth rated for diving.

1-Deployment- The P20 / M60L’s simple geometrical shape suggest that they may be easily stowed and deployed in a manner similar to other such lights. They easily slide in and out of pockets and their clips handsomely perch the lights on the edge of even the finest uniform or gent's trouser pocket. The NightCutter P20 / M60L On/Off functionality is simple to activate and follows the use model of many similar lights of this caliber. It should be noted that the energy and throw required to momentarily activate these lights can be as little as 1/2mm making them an excellent choice in circumstances where the heavy tail switch pressure demanded of other tactical lights may not be required. The second advantage that the NightCutter P20 / M60L have in this switch approach is that they may be securely placed tail down on a flat surface for ceiling bounce mode- a useful option for creating a general diffused canopy of light.
2-Basic Use Model . The switch is at the tail end rather than at the head.
3-Changing 'States'- Focus is fixed at the optimal beam angle produced by the matched reflector or optics.The switch functional model is standard and since there are only three states, it's easy to learn
4-Usage Options The P20 / M60L are lights that can be carried or stowed loosely in a pocket or compartment, or they may be attached to a tether through their sizable ring holes.

Footnotes:

(*1) Medium Men's glove size- Also, a Standardized Flashlight Hand Size Metric (SFHSM)

		Small A-B = 4.5" or Shorter
		Medium A-B = 4.5"-5"
		Large A-B = 5"-6"
		X-Large A-B = 6" and Longer

(*2) Maximum Distance for Object Identification (MDOI). The maximum distance that a person without the aid of magnification-can with normal or corrected vision, under a given ambient level of light, identify an object of known size, and clearly distinguish it from its surroundings. We have tentatively identified the following scenarios for such measures:

• A single average sized person/body identification scenario
  • Urban (city, inside buildings, dark alley, lit streets)
  • Rural (countryside,farm residential backyard)
  • Environmental (dessert, woods, wetlands, over water)
  • Natural & manmade disaster (fire, flood/mudslide,earthquake, hurricane /tornado,bombing scene, collapsed structure etc)
• Small Inanimate Object (smaller than a shoe-box)
• Medium Inanimate Object (Black Plastic 33 Gallon (124Litre) Garbage Bag stuffed with a big sleeping bag)

(*3) Usability testing results - in progress.

(*5) Context Inclusive Illumination Window (CIIW) as compared with a Context Exclusive Illumination Window (CEIW) .

• CIIW describes a subject illumination paradigm wherein the illumination target is the focus of the beam's brightest disc or 'Hotspot' and peripheral objects to the target are more dimly illuminated in a larger disc that surrounds the focus or hotspot. This outer region is also referred to as a corona or penumbra.
• CEIW describes a subject illumination paradigm wherein the illumination target is the focus of the beam's brightest disc or 'Hotspot' and peripheral objects to the target are not sufficiently illuminated to be easily discernable at the periphery of subject beam's focus or hotspot.
