Form Factor & Build
|
1- The
Fenix LOP series are ’fingertip’
sized keychain pocket flashlight that pays cursory homage
in its form-factor to a well known keychain flashlight –
the MAG Solitaire. The Fenix LOP uses a 1Watt
Luxeon LED powered by a single AAA cell battery. The Fenix
LOP is a mass produced personal tool that exudes
high quality fabrication in a production flashlight.
2- The light is a radially symmetrical cylinder with only
a bilaterally symmetrical tailpiece- differentiated from the
head by a unique keyring terminal attachment approach.
3- Though minuscule, the Fenix LOP compensates
for its diminutive size and differentiates it from the Solitaire
profile, by providing subtle yet noticeable variations between
surface treatmet at strategic regions.
4- The Fenix LOP is a two or three fingertip
light- ideal for situations where the maximum output combined
with the smallest and lightest form factor are essential.
This makes it useful for individuals of all hand sizes and
in situations where compactness is the key usability criterion.
5- All sections are crafted with precision and fit together
very precisely with an extremely smooth threading action.
One notices from taking the Fenix LOP apart
that it is a tool made with high precision CNC engineering.
6- There is no 'play' or rattle anywhere in the Fenix
LOP. A single 'O' ring seals the junctions between
sections and provides, a snug fit and a seal against the elements-
especially water. An additional 'O' ring seal prevents water
from entering the bezel through the front lens. |
| Ergonomics
& Mount Options |
1- The flashlight
is ambidextrous.
2- The Fenix LOP allows for single-handed On/Off operation. The
first finger and thumb of the supporting hand may turn the head
to activate and de-activate the light. Alternatively, a couple
of fingers of one hand may hold the body while the fingers of
the other-turns the head.
3- Battery changes are effected through separation of the battery
compartment from the fore-end of the light
4- A 1mm diameter hole in the tailpiece allows for the attachment
of a split-ring and a slot allows for that split ring to be
maneuvered away from the tail- allowing thelight to stand, unencumbered
in an upright posture. A second hole acts as an alternative
attachment point, for tether or lanyard string. |
| Affordances |
1-
Stowage- None Applicable – keyring hole in tailcap.
2-Basic activation- in normal use, light emits from the front
of the flashlight when activation occurs through a full clockwise
turning of the fore-end against the rear-section. There is
no follow-through before turning stops. reversing the process
effects de-activation.
3- A single 'O' ring protects the battery compartment from
the environment . Contact pressure with the battery is furnished
by a coiled spring in the tailpiece.

| Human
Factors & Usability |
1-The
Fenix LOP’s On/Off functionality is
standard and fundamentally as simple to activate as any of
several flashlights of its genre. As such, its cognitive usage
model is mostly familiar to people with prior experience with
the MAG Solitaire while the Fenix LOP has
the added convenience of a single ‘focus’ setting
– a fact that discourages constant adjustment and re-adjustment.
2- An extraordinary usability characteristic of the
Fenix LOP- is the fact that it produces a
very wide and relatively bright beam for its tiny size- making
it suitable for near distance navigation in addition to general
searching
3- We didn’t perform physical tests but judged that
the lack of knurling would not bee too great an issue in preventing
slippage and loss in most situations, even with wet or gloved
hands. A natural grip is formed by the flat milling of the
hexagonal body section
4- The Fenix LOP is a light
that can be carried by itself, on a lanyard or on a keychain.
As such, this it highly versatile for many end-users with
varied preferences for stowage. As is often the case with
keychain lights, the keychain itself-with its attached keys
are most of the ‘handle’ while the light may only
be partly supported by the user’s hand. The great advantage
of the Fenix LOP is that it can be used instead
bulkier lights to give a premium quality of illumination.

| Beam
Quality & Characteristics |
1- The smooth parabolic
reflector of the Fenix LOP creates a circular
combination beam that is a broad flood of light pierced by a
focused circular hotspot at its center. This is a typical beam
‘profile’ for Luxeon emitters used in combination
with parabolic reflectors.
2- The wide round-shaped beam is excellent for general searching
and is bright and focused enough to create moderately bright
direct ambient room lighting in a small to average sized room
and still delivers relatively bright light through hand-held
or table supported ceiling bounce mode (18'X12' white ceiling
+ white walls).
3-The Fenix LOP creates a subject illumination in a category that
we've codified as a highly Context Inclusive Illumination
Window (CIIW) as compared with a Context Exclusive Illumination
Window (CEIW) (*5)
4- For one test, we used the Fenix LOP for a typical key-chain
light task of illuminating a keyhole. In this test it exceeded
most user needs- casting both a broad beam on half of the door
as well as producing a bright and focused spot on the doorknob
and a good deal of area surrounding it as well. Being substantially
brighter than most keychain lights in its size class- and due
to it’s wide beam, it served well in close to moderate
range navigation around a house and around an automobile- as
well as for searching dark nooks and crannies at close range.
Searching around the trunk of a car and around the wheels- we
predict that it could be pressed into service as an excellent
short runtime emergency light. It admirably performed tasks
that we typically associate with larger lights. Navigating dark
corridors for example, or scanning a large back yard were easy
for the Fenix LOP
5- There is only a slightly blue bias to the otherwise perceptually
white beam. Though not noticable in practice, it is noticably
bluer than somewhat pricier comparable lights- that may posess
neutral BIN emitters.
6- The wide corona coupled with its diminutive size, give it
‘powerhouse’ status in most emergency situations
typically reserved for much larger and heavier flashlights.
7-To test the throw of the Fenix LOP, we conducted
a Maximum Distance for Object Identification or MDOI
(*2) trial and managed to confidently differentiate our test
subject (a Black Man’s briefcase) from its immediate surroundings,
from as far away as 40 feet with the subject
area in near total darkness and the evaluators and flashlight
in a moderate level of street sodium vapor ambient lighting
(RH=20% at 38ºf). This test simulated a person searching for
an object of known size -a briefcase for example- but situated
in a leafy camouflaged setting, such as dense underbrush for
example. From 40 feet away , the Fenix
LOP positively lit up the vegetation surrounding our
subject enough to clearly distinguish it from the Black Man’s
Briefcase, which lay on the ground. The estimated contrast ratio
was 2:1 |

The color chart tests
photographed with a digital camera set for Daylight White Balance
and exposure set- to properly expose the gray areas of the chart
to 50% or Zone V- 'Mid-tone Gray', revealed a color temperature
of roughly 6000ºK. Comparing the Fenix LOP
chart photograph with a flash (White Balance set to 'Flash')
exposure of the same chart reveals a slight bias to blue. This
makes it useful in situations demanding good fidelity color
differentiation. The Fenix LOP
is not intended as a forensics or artwork appreciation illuminator. |
| Brightness |
The
Fenix LOP scored Maximum
Distance for Object Identification or MDOI at 40 feet
-more than adequate for general searching or navigation in
an emergency- though not really sufficient in tasks with which
larger and more powerful lights are typically associated -such
as tactical or emergencies of long durations or covering a
wide field.
|
| Conclusions |
1- The
Fenix LOP is an elegant and well made high performance flashlight
that's ideal for close-range tasks including: wearable personal
illumination, emergency, and as a back-up to larger flashlights.
We judge it to be an excellent choice for near-range general
nocturnal activities as well as for everyday personal carry.
2- The Fenix LOP will not disappoint potential
owners that expect state of the art performance combined with
high quality production build. It exudes the kind of quality
one associates with custom made personal tools.
3- Outstanding features include:
- Excellent aesthetics
- Modern surface treatment and durable Hard Anodizing III
- Surprisingly wide, smooth beam color for its size
- Excellent runtime performance
4-Value.The Fenix LOP is
a mass produced product and yet it serves its owners with performance
and build quality that surpasses its ‘street price’.
At this point in time, the Fenix LOP
rates 4.95 stars out of a possible 5 stars.
Our gripes were... A) Slightly bluish emitter B) Mineral glass
lens is subject to breakage.

(*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)

(*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.
