1-Controls- in normal use, light emits from the front of the flashlight when activation occurs through a full clockwise turning of the head (or tail in the case of the 3LED version) . There is no follow-through after it's fully On . A scant -2º anticlockwise turning of the head in relation to the body conversely effects de-activation.
2-Component/Section Accessibility The head section is threaded to the body section, allowing for access into the battery compartment. The circuitry and emitter are 'potted' with an epoxy like compound into the bezel as an integrated and non- modifiable assembly. The tail section of the 3LED version is thus a second access point in that model.

1-Deployment The Matterhorns’ form factor and size suggest that they may be stowed and deployed in a manner similar to other lights of this category. No sheath or holster or tether are offered but aftermarket accessories exists that may be used with these lights. Not all users will feel a need to in any manner secure their lights other that to simply put them down somewhere or drop them into a pocket. These lights , like others of their kind are candidates for neck-lanyard carry either around the neck or inside a pocket with the lanyard attached to a belt loop. Such anchors make locating and deploying the lights much easier.
2-Basic Use Model . The switch is at the head end for both lights and the tail section of the 3 LED model may be used as a switch as well. There are no buttons to press or levers to throw, making the use model intuitive and easy for anyone to learn.
3-Changing 'States'- Focus is fixed at the optimal beam angle produced by the matched reflector (1LED style) or LED silos ( 3 LED style). The twisting action for activating/de-activating the light is standard for such lights.
4-Usage Options The Matterhorns are small enough to use as key chain lights for keyhole location or they may be pressed into service as a highly respectable near to mid-distance torches. It's doubtless that they may be used for a wide range of tasks. The twisting activation model makes them impractical for signaling but they are highly reliable survival quality lights that would easily withstand the rigors of a grueling adventure as gracefully as they manage the modest demands of everyday use.

Footnotes:

(*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.
