Form Factor & Build
|
- The Light Pro SpitFire-1
is a modern interpretation of the classic hand-held flashlight
shape. Its geometry is a radially symmetrical round cross-section/featuring
a scalloped (9 scallops) anti-roll head, unique circumfrencial
knurling, and a deeply grooved tailcap.
- The head of the SpitFire-1 is much wider
than the body and tail-piece which are the same diameter.
- This flashlight pays deep homage in its appearance to the
Longbow Micra with Turbo-head attachment. A compact little
powerhouse in a small hand-the SpitFire-1
would be equally comfortable comfortable in a medium or large
hand.
- One's hand surrounds the smooth but uniquely tenacious body
of the light.The light fills half a medium (*1)
sized palm with no protrusion from small or medium hands.
- Nine understated 'scallop notches' cut into the bezel collar,
effectively prevent the light from rolling on a smooth surface
and add an industrial look to it.
- The aluminum wall thickness of the battery tube is 3 mm.
- All sections fit very well and threading action is smooth.
- Type II (Matte) anodizing on the outside and inside the
battery compartment - offers some protection against corrosion.
- Matte black finish minimizes reflections and visibility
at night.
- There is very little battery rattle
- Substantial 'O' rings provide some shock absorption, a snug
fit and a seal against the elements.
- The included lightweight cordura nylon sheath is effective
though somewhat generic looking.
- A nylon wrist lanyard reduces the likelyhood of accidental
loss during use.
- Very elegant and professional look & feel with moderate
heft. It 's a value candidate in the 1W Luxeon flashlight
market |
| Ergonomics
& Mount Options |
1-
Ambidextrous.
2- A medium palm completely surrounds the
body of the SpitFire-1, with the thumb and
first or second fingers- naturally positioned on the front
of the body in the sweeping curve that creates a smooth transition
from the head down to the body section. It's ideal for all
hand sizes from youths to big handed adults. It may be hand-held
in various positions including: Harries Flashlight Technique,Rodgers,
forward, upward and downward pointing 'standard' flashlight
hand-held modes.
3- An improved momentary 'On' /Twist- On/Off
tail-piece switch allows for constant or intermittent light
activation. The tail-piece may be counterclockwise rotated
-120º for 'Full lock-out', preventing inadvertent activation.
4- No native mounting options for fire arms
use are evident, though the mid-section may allow for dedicated
clamping brackets or other improvised and custom designed
attachment solutions. |
| Affordances |
1-
Stowage- A black Velcro secured holster/sheath is included.
It allows for belt carry in the vertical orientation on belts
measuring 2.9 inches or narrower. There is no provision for
horizontal belt mounting, but a second carry option allows
for 'over-belt' attachment to belts 2.5" or narrower.
2 - Activation- In normal
use, light emits from the front of the flashlight when activation
occurs through a full clockwise turning of the tail-piece
till it stops. There is around 2º of 'follow-through'. De-activation
is implemented via an anti-clockwise turning of the tail-piece
by only around 4º. In the 'Off' position, a partial (soft)
activation of the momentary button switch causes the light
to turn on. An immediate release of pressure, causes the light
to turn back off.This is known as 'momentary' mode. Intuitive
use involves one hand holding the light while the free hand
turns the tailpiece or with the light in 'Off' mode, one hand
may be used to activate the light in the Harries hold for
example. The tailpiece may also be turned with just the fingers
of the supporting hand. Locking out the momentary button requires
a -120º for 'Full lock-out', preventing inadvertent activation.
3-The head is removable from the body section
with allowing access to the front 25mm optic in bezel as well
as to the LED assembly- mounted in the front of the body section.
4- The removeable tailpiece protects the battery
compartment from the environment by a sufficient 'O' ring
and substantial thread lubrication.

| Human
Factors & Usability |
1-Matte
black anodizing protects the surface that is machined throughout.
2-As implemented in the SpitFire-1,
the knotched bezel collar is elegantly decorative and functional.
Unique circufrential grooves on the body section and around
the bezel offer a substantial gripping advantage over a totally
smooth surface.
3- We did not perform a 'pull' test but we
judged that this grooving of the surface of the SpitFire1
should provide substantial fore-aft grip even with moderately
wet or oily hands. It was superbly aggressive in dry and gloved
hands- surpasing some of the customary 'diamond' patterns
that we've seen often on flashlights of this class.
4- The compactness and brightness of this
light make it very suitable for briefcase, security, law enforcement,home,
car, camping or workshop tool box. It is certainly suited
for outdoors,and moderate to rough environmental exposure.
5- We liked this light best as a potent all
purpose light. As a compact source of bright emergency illumination
or as a compact camping and tool box flashlight, it's output
to weight ratio made it preferable over longer or heavier
lights. It really deserves to be used in situations when a
focused beam is of primary importance.
6-The On/Off activation procedure is a significant
improvement when compared to the LightRover, another light
from the same company. The switch is very intuitive and the
cognitive model is simple and easy to remember. It offers
a silent non-clicking alternative to the Kroll type switches
that are common in these types of flashlights.

| Beam
Quality & Characteristics |
1-
The beam is narrow and round shaped with a round hotspot -
using a 25mm diameter collimating optic.
2- The round-shaped beam was excellent for
general searching and was focused enough to create sufficient
ambient room lighting through ceiling bounce mode . It is
suitable for candle mode due to the user's ability to expose
the LED by removing the front bezel. It 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)
3- For one test, We used the SpitFire-1
with its included wrist lanyard and walked around the neighborhood
peering into neighbors automobiles. It easily pierced the
dirtiest automobile glass windows- revealing all manner of
objects and debris. For another test we used the SpitFire-1
to light up the entire side of a small single family home
from more that 100' away.
4- There is a little unevenness in the beam's
tonal distribution.The brighter hotspot is surrounded by a
narrow 'corona' or penumbra that furnishes some context inclusive
illumination. I would characterize such a beam as a spot .
It would serve admirably for security,camping and general
emergencies.
5- The 25mm optic is probably calculated
to satisfy customers seeking the most efficient collimation
of the 1W LED- and the SpitFire-1 delivers
that . Unfortunately, two concentric 'Saturn's Rings' provide
little in the way of lighting assistance but in fact may be
distracting in close distance indoor tasks.
6-To test the throw of the SpitFire-1,
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 140
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=73% at 73ºf). 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
140 feet away, the SpitFire-1 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 2:1

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 a color temperature of roughly 5,800ºK. Comparing the
SpitFire-1 chart photograph with a flash (White
Balance set to 'Flash') exposure of the same chart reveals a
slight bias to blue. This makes it less useful in situations
that include a high level of water vapour or smoke in the air
(due to scatter and diffusion) but more than sufficient for
general color differentiation and object identification or scene
illumination. The addition of a 1/8 CTO over the lens would
balance the SpitFire-1's light with daylight
at high noon.

TheLite-Pro
SpitFire-1 scored Maximum Distance
for Object Identification or MDOI at 140
feet -quite enough for general searching,
close up inspection and general to specialized flashlight
tasks.

| Conclusions |
1-
The SpitFire-1 is a medium duty personal
flashlight that's ideal for general flashlight tasks in a
number of everyday and some professional situations. We feel
confident in recommending it as a budget priced tactical light.
2- This light provides very intense 'close-up'
illumination and it delivers a punchy beam that maintains
a fixed focus over a 140 foot range.
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 SpitFire-1 rates 4.25
stars out of a possible 5 stars.
Our gripes were... A) The tailcap does not permit vertical
stance for 'ceiling-bounce' mode- especially since the convex
button-shape serves no practical purpose B) LED color should
be less blue
4.25 Stars-
Very Recommended
Pros= Exceptionally informative, accessible
& appealing packaging | Well formulated optic optimizes
for efficiency the LED's output for a brighter spotlight than
comparable lights | Silent tailswitch is a viable alternative
to noisy click switches | Competitive limited lifetime warranty
| Unique grooved surface enhances grip without roughing up a
sleek silhouette
Cons= The tailcap does not permit vertical
stance for 'ceiling-bounce' mode | The LED color should be less
blue | 1/16" lanyard hole is too narrow for some rings
or clips to pass through and makes lanyard threading a challenge.

(*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)
(*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 weherein 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.
