Form Factor & Build

1-Classification- The Medium 360º is unique in that it provides a permanently flexible 'gooseneck' extension that allows the user to position its head separately from the orientation of the body. As such, the Medium 360º is an ideal product for shining light into tight crevices and around corners in a manner that's beyond the means of flashlights that don't have such capabilities. It is in fact the middle sized member of a group of such lights from LED Lenser. As such it is really a specialized illumination device that may nonetheless be used in a fashion similar to other small flashlights. Being a single AAA battery user, it allows for inexpensive and easily accessible replacements, making it economical for individuals that may use such a product regularly.
2- Geometry- it is radially symmetrical cylinder.
3- Build Quality- The Medium 360º is made of brass that has been matte Nickel plated. These is mass production high quality light that is suitable for light duty everyday or occasional use.
4- Physical Features -The Medium 360º has substantial heft and is thus less likely to end up on a baseball cap or the breast pocket of a fine dress shirt .It would be appropriate for a journeyman's work shirt, or any professional's outer gear. It would also be the ideal type of illumination for anyone that must peer into and inspect labyrinthine equipment such as computers, electrical boxes and so on.
5- Wall Thickness- The aluminum wall thickness of the battery tube is .5mm.
6- Finish- Matte nickel plated Brass. The use of brass makes it sturdy and gives it a feel that one associates with solid objects.
7- Fit- The tailpiece fits well with some roughness of threading but with no play whatsoever.

Ergonomics & Mount Options 1- Laterality Dominance. The flashlight is ambidextrous.
2-Switch Activation The Medium 360º is activated by a firm pressing of the 8mm diameter black click switch button- located at the fore of the body section. This micro switch button is covered in a protective black elastomer- making it water resistant . A gentler pressing allows the light to be turned on momentarily.
3- Battery Changes are effected through removal of the tailpiece from the body section.
4-Loss Prevention/Stowage-A plated removable spring steel pocket clip allows it to be used in a pocket or other such manner.
5-Handling. The Medium 360º handles well- 'pointing' easily. The flexible gooseneck allows for a fairly accurate positioning of the head with between 0" and .5" of spring-back.Contrary to it's name, this light does not allow for a true 360º of range of motion, but it does allow for a about 320º in a nearly spherical axis.
Affordances

1-Controls- The side click On/Off switch button is the only control devices. The flexible neck is positioned by the user's hand .There is no provision for locking the head in any position.
2-Component/Section Accessibility Only the battery compartment is accessible.

Human Factors & Usability

1-Deployment The Medium 360º’s form factors and size suggest that it may be stowed and deployed in a manner similar to other lights of this category. It is sold in an attractive presentation case that contains a black high density insert- precut so that the light may be stored in a 'U' shape. This insert may be removed in order to stow the light in another host container if desired.
3-Changing 'States'- Focus is at one relatively omni directional setting.There are no other settings for either focus or intensity.
4-Usage Options The Medium 360º is clearly a 'problem solver' type of illumination tool for people that must inspect, craft or repair. We did discover that it also makes an excellent reading light- either clipped to the cover of a book or the center spread of a magazine. Because it has a flat tail-piece, the Medium 360º may be stood upright on a flat surface with the gooseneck positioned downwards. It may also be laid down on its side for a multitude of other applications.

Beam Quality & Characteristics 1-Beam Characteristics-This light produces a soft edged medium wide beam.
2-Color compared to 5,500ºK (Daylight) -5,000 ºK (approximate)
3. Recommended Filters - N/A
4-Context of Use -cornering and peering inside other wise inaccessible small spaces - especially within machines/equipment.
5-Category The Medium 360º creates a subject illumination in a category that we've codified as Context Exclusive Illumination Window (CEIW) as compared with a Context Inclusive Illumination Window (CIIW)(*5)
6-Usage Scenarios. Anywhere a flexible neck light is needed.
7-Throw-Maximum Distance for Object Identification or MDOI-Confidently differentiate our test subject (a 3.5"X4.5"Black Wallet) from its immediate surroundings (black asphalt street), from as far away as 10 feet. This test simulated a person searching for a known object of known color/tone that may be difficult to distinguish from its surroundings in ambient light.
8-Percieved Brightness . Average for a one Nichia type LED lights in its size category.
Conclusions

1-Summary Comments-The Medium 360º is a well crafted mass produced flashlights from a reputable manufacturer of personal illumination tools. It is an elegant problem solving tool for consummate inspectors and repair persons working in tight and cramped spaces.
2- Outstanding features:
- Excellent fabrication quality
- Sufficiently bright beam for its class
- Competitively priced
- Good aftermarket support
- Common battery type
- Handy flexible gooseneck
- Stylish design and gift worthy packaging
3-Value. Good quality to price-point ratio.
4-Areas Cited For Improvement A) Deserves to be offered with a tiny inspection mirror attachment B) The side switch may be slow for some to use and requires more pressure to activate than some may like.

4.5 Stars-Highly Recommended

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.
