Form
Factor & Build
|
- Sleek and industrial
aesthetic. A contemporary hand-held flashlight. Geomerty is
a bi-laterally symmetrical round cross-section/featuring 2
opposing flat milled sections, strategic & functional
knurling and 'cooling fin' accents.
- Entire flashlight profile is geometrically a nearly uniform
diameter cylinder with cut-in (turned & milled) accents.
- The flashlight feels lightweight (with batteries) yet it
gives the impression of having respectable heft.
- The aluminum wall thickness of the battery tube is 2 mm.
- All sections fit precisely and threading action is fast
& smooth.
- Anodizing throughout (presumably) makes highly corrosion
resistant -it exudes detailed quality.
- There is no 'play' or rattle anywhere. 'O' rings provide
shock absorption, a snug fit and a seal against the elements-
especially water.
- Rugged look & feel with handsome and minimalist contours.
It reminded us of the Hummer automobile and the milling suggests
that this light would make a nice partner to the Extrema Ratio
'Nemesis' -folding knife. As such, its as elegant in a briefcase
as it would be reliable on the battlefield or a campsite. |
| Ergonomics
& Mount Options |
1-
Ambidextrous. Even more pleasant to hold than to behold
2- One's hand easily surrounds the smooth
round body of the Mini , with the thumb and first or second
fingers- naturally locating the flat milled sections at just
behind the head-section.(*3)The body
of the light fills an entire medium (*1)
sized palm without protruding at the wrist. Its ideal for
smaller hands but eminently hold-able by medium or large hands
as well. A 'forward hold' on the head section may be used
with third finger fitting naturally into the underside flat
cut-in. It may be hand-held in various positions including:
Harries Flashlight Technique,Rogers hold, forward, upward
and downward pointing 'standard' flashlight hand-held modes.
The lack of customary knurling over the body section is a
refreshing departure from the norm (our tests have shown that
knurling shinny anodized metal does not always yield a better
griping surface) and is more than compensated for by the grip-ability
of the cut-in flat-milled sections. Knurling on the tail cap
does seem tofacilitate easier turning and therefore, On/Off
functionality.
3-Two dep grooves cut-in at the rear of the
head may aid 'indexing' (by aiding in head or tail identification
in total darkness) as well as performing the cooling fin function
of dissipating heat away from the LED capsule and reducing
surface temperature where a hand may otherwise experience
discomfort. An imprinted warning on the head section reads
'Caution: Hot Surface' and the international symbol for 'Hot
Surface' in imprinted above that.
4-Three attachment points on the tail cap-
allow for a variety of attachment options.
-- One 1/4"X20 threaded hole positioned at the center
of the tail cap is suitable for lanyard adapter or other 1/4X20
connection.
-- One 1/4"X20 threaded hole positioned at one side edge-90º
to the end hole of the tail cap is suitable for tripod/bipod
or other 1/4X20 connection
-- One 1/8"D (3mm) smooth & round lanyard hole is
positioned diametrically opposite to the side-drilled 1/4X20
threaded hole and is suitable for a ring, spring-clip or cord
lanyard attachment
5- Thanks to a flat tail cap and coupled
with light weight and excellent 'balance' (center of gravity
is dead-on at the midpoint along the length of the light),
'candle/ceiling mode' are very stable with this flashlight.
6- No other native mounting options for fire
arms , though the mid-section lends itself to dedicated clamping
brackets or other improvised and custom designed attachment
solutions. |
| Affordances |
1-
Stowage- No stowage pouch/holster/sheath are offered- though
third party ones should be plentiful.
2- In normal use, light is emitted from the
front of the flashlight when activation occurs through a clockwise
turning motion of the tail cap. Once it stops turning the light
comes on.There is no 'follow-through'point for this activation.
Intuitive use involves a supporting hand- holding the flashlight
while the free hand rotates the tail cap at the rear intill
it stops. 'Negative' contact causes the light to turn on. Alternatively,
the light may be held in the rearward/downward pointing position
in just one hand- while the thumb and first finger of the same
hand then force the tail cap to turn around to make the light
come on. Though a little awkward at first- this second option
in nonetheless allows for single-handed operation.
3-The head is comprised of two sections.The
front of the bezel (called 'Mini-lens cap' by Longbow's instruction
manual) may be unscrewed to access the optic, a retaining'O'ring
(gasket #3),and lens or 'optic shield'. These are user-replaceable/cross-gradable
parts. Behind the front-section is what Longbow calls the 'Mini
bezel' which houses the 'LED Capsule', more gaskets follow and
then the battery tube or body section and tail cap. The tail
cap. is protected from water entry by two 'O' rings. This level
of redundancy ensures waterproofing to greater depths than most
flashlights in the Mini's price-range & class typically
deliver. Suffice it to say that the entire flashlight may be
entirely disassembled for parts replacement and cross-grade,
maintenance or inspection- without the need for any tools or
great physical strength. |
| Human
Factors & Usability |
1-Anodizing
protects a satin smooth surface that is finely machined along
the body section with a series of micro-grooves that make
the surface 'feel' like it has a finely tooled pattern engraved
into it. It's a pleasure to experience this signature of the
manufacturing process. The Hard anodizing doesn't have a glossy
look or slippery feel as sometimes is the case with flashlights.
As mentioned in the section (Ergonomics & Mount Options),
The light's contours and machined profile seem designed to
be held securely in ones hands. We did not perform a 'pull'
test but it was obvious that the light was both easy to manipulate
with one hand - and not about to slip away from it's operator.
2-The lack of a holster (useful for protecting
the light and especially its lens) is more than made up for
by the attachment points previously cited. As such it operated
very well as a 'tethered' light- hanging from this reviewer's
personal neck lanyard (via a 'lobsterclaw' clip + split ring)-
and was at the ready and not easily losable or drop-able.
An accessory coiled & tangle- free lanyard would be a
welcome accessory for those that prefer to tether the light
away from thier neck. In addition, Longbow are releasing a
'Button' style belt clip for belt carry - a belt-carry solution
borrowed from the mobile phone industry.
3- The lightness and compact form factor
make it suitable for pocket carry (depending on the type of
pocket). It may also be ostensibly used as a Kubotan/Baton
light . It is certainly suited for outdoors, water-sport and
rough environmental exposure- where reliability and toughness
are of paramount importance.
4- In using it continuously for a 1/2 hour
in 70ºf ambient , I barely sensed that the head was too warm
to touch by any means. I suspect that the warning imprinted
on the head is more to protect against potential liability
than as a caution of any significan heat issue.
5-The tail cap (twist on /off ) switch needs
barely a few degrees of an anti-clockwise turning to switch
the light 'Off' . Turning it a little more ensures that the
light doesn't accidentally come on by itself
for any reason (untested) . A tail cap push-button switch
would facilitate easier single-handed operation (untested)as
well as afford the use of momentary 'On' mode, arguably a
useful option in certain situations. As an example, on a nightly
walk with this light I typically turned it 'On/Off' about
6 or 7 times in the course of 10 minutes - so as to conserve
battery power by avoiding 'drainag' on well lit stretches
of road. The firm turning motion required to operate the twist
switch mechanism of the Mini,makes is inconvenient
in situations that involve a lot of repetitive on/off cycles
within a short span of time. For such situations, a click
on/off type switch would be the more conveinient option.One
advantage of the Longbow designed twist on /off tail-cap is
that a lanyard may be attached to allow for direct downwards
pointing beams- ideal for tracing ones steps through a dark
passage with both hands otherwise occupied, or for tent or
other directly down-ward pointing illumination.
6- The color of the 'Olive Drab' sample Mini
we reviewed is actually more of a warm & dark gray- The
colors Anthracite and Carbon
spring to mind. Its nearly identical to Pantone Matching
System color #405(MC)(*4). Tis
nearly neutral Gray camouflages & blends in well with
a variety of 'Olive Drab' or 'OD' products that we sampled
at a local military surplus store. It also compliments warm
grays,breen or greeninsh browns,titanium,carbon,bronze,gold,brass,raw
aluminum,black, tan, sand and white. |
| Beam
Quality & Characteristics |
1-
The beam is square shaped, though with softer edges than we've
seen from similar optics/lights. The narrowness of the 6º
hotspot capitalizes on the clean brightness of a premium Bin
1 Watt Luxeon emitter, while still delivering a useful spill
of around 12º beam angle. I would characterize such a beam
as 'tactical' -as its very similar to the beams put out by
several tactical weapons lights.It would serve admirably for
search/rescue, ems, law enforcement, military and extreme
outdoor sports.
2- The square-shaped beam didn't affect our
ability to use this light normally for searching or to create
ambient room lighting through ceiling bounce or candle mode
modes. It creates a subject illumination in a category that
we've codified as a Context Inclusive Illumination
Window (CIIW) as compared with a Context
Exclusive Illumination Window (CEIW) (*5)
3- For one test, I mounted the Mini in my
preferred holder- a Nite-ize headband, and ran a local woodland
trail for 2 miles. It easily illuminated the blue blazing
on trees as far away as 320 feet (about 100 Meters), creating
a subject circle of about 2 meters in circumference.
4- The beam lacks any artifacting or anomalies
that might adversly affect the judgment of illuminated subjects
at normal distances for this type of a light. Simply put -
it works perfectly -right out of the box.
5- While the supplied optic is probably ideal
for a wide range of uses- accessory heads extend the functionality
of the Mini to more specialized contexts- a welcome approach
to user and task centered design.
6-To test the throw of the Mini, we conducted
a Maximum Distance for Object Identification or MDOI
(*2) trial and managed to confidently
differentiate our test subject (a Black 33 Gallon
(124Litre) Trash Bag) from its immediate surroundings,
from as far away as 145 feet (44.2 Meters) with the subject
area in near total darkness and the evaluators and flashlight
in a moderate level of street sodium vapour ambient lighting.
This test simulated a person searching for an object of known
size -a person for example- but located in an unknown or difficult
to spot container -a black trash bag, for example. From
145 (44.2 Meters) feet away, the Mini positively lit up the
vegetation surrounding our subject enough to clearly distinguish
it from the Black 33 Gallon Trash Bag, that lay on the ground.The
estimated contrast ratio was 3:1

Quality |
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 that the manufacturer stated color temperature rating
of 5,500ºK is accurate. Comparing our Mini chart photograph
with a flash (White Balance set to 'Flash') exposure of the
same chart reveals an ever so slight tendency towards Blue (sometimes
cited as "violet" by some reviewers). This would make
the Bin of the particular Luxeon in the Mini we reviewed a TWAK
or nearly so. This makes it superior in situations that demand
the highest caliber of color differentiation. It could probably
be used to make an accurate color photograph that would rival
one made in natural daylight at high noon or with flash.
2-In general, our experience has shown that
such pure white light is eminently suited to forensic, search
and rescue and generally indoor use in clear-air spaces. Pure
White or Blue biased light has been, problematic in tests where
a substantial amount of water vapor,mist, dust, pollen or other
fine particles are in the air due to the tendency for such particles
to reflect, diffuse and other wise degrade the light beams as
they travel to their subject destination. For such situations,
yellow, amber or red filters or lights towards the yellow/orange/red
end of the spectrum seem to have better penetration. Having
said this, the Longbow Mini cut right through 145 feet of dust
and pollen on an evening with RH of 55% without causing any
glare!

| Brightness |
I don't possess
a light meter but the findings of other reviewers are hereby
underscored and confirmed- It's as bright or brighter than
any 1 Luxeon light we've experienced to date. It's brightness
was such that it properly exposed the reference color chart
for 50% Gray at 1 stop smaller aperture than the only competitor
on hand, a Vortex TC2 ( W/Fraen ) . This is corroborated by
the fact that the Vortex TC2 scored Maximum Distance
for Object Identification or MDOI at only 100 feet
(30Meters) versus the further (and better) 145 feet
(44.2 Meters) from the Longbow Mini (*4).
That Longbow Mini optic has reach and punch.

| Conclusions |
1-
We only had this light to test for 24 hours and our first
impression was that based on the beautifully crafted and designed
presentation box we felt good about it even before the box
had been opened. It's easy to overlook presentation and branding
in the niche products market. The designers of the
Longbow and it's packaging, clearly spared no expense in talent
or materials. We suspect that a lot of these flashlights
might well be marketed through the high-end retail channels
and we see them being offered as gifts. The build quality
coupled with raw performance thus frames a picture of a handsome,
rugged, verile and well dressed flashlight- eager to punch
light into the darkest labyrinths or to reach out across a
distance and illuminate an obscure subject. (*4)
2- This light provides intense 'close-up'
illumination and it delivers a bright diffused overhead light
when used in ceiling/bounce mode (optics on- pointed at a
light colored ceiling). For close-ups there are lights that
contain variable resistors and circuits to reduce the output
to manageable levels. Another option would be for Longbow
to offer an accessory Lantern Attachment or Filter
that would diffuse light from the stock optic, without the
need for removal of the head assembly
3-Value. With new flashlights in the 1 &
2,CR123 / 1W Luxeon market space -being released weekly- it's
hard to define a relative value when comparing non-comparables.
At this point in time, the Longbow Mini rates as our
top choice in it's price and quality class - for
it was hard to fault the package or product. We've award it
5 stars out of a possible 5 stars.
4- Our minor gripes were... A) The milling
of the flat cut-in sections- on the sides of the body section
(Battery tube) showed the faintest tooling marks from the
milling bit used to cut the insets. This is a very slight
'finishing' issue... un-obstrusive and hardly mentionable.
B) The package we received, depicted a Longbow Micra, even
though it contained a Mini. I would not have noticed that
at all-were it not for an observant assistant remarking that
the serial number sticker on the back of the box was positioned
directly over the Mini's description. (#6)
Unless future packages match the cover photograph exactly
to the contents or some sort of a sticker labels the model
clearly for store customers , we predict there might be some
confusion at retail points of purchase. These two minor issues
were all that kept the Mini from earning a perfect score.

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)
