Form Factor & Build
|
1- Modern industrial interpretation of the
classic hand-held flashlight form. Geometry is a radially
symmetrical round cross-section / featuring some 'Machine
Age' elements such as the square grid pattern grip and tailcap
treatment as well as the accent of a contrasting stainless
steel bezel front and tail switch protector. These aspects
give the INOVA T3 an understated industrial
elegance. The INOVA T3 is built and styled
in the fashion of the most contemporary designer flashlights-
exuding sartorial poise and yet delivering the necessary output
performance to match its aesthetic persona.
2- The Heavy duty stainless steel bezel front
not only adds a touch of flair to the otherwise all black
instrument, but in addition it serves to protect the optic
and front end of the light from the inevitable dings and dents
that accompany real-world use.
3- The head of light is wider than the body
& tail-piece which are approximately the same diameter.
4- The flashlight feels significantly heavier
than many flashlights of comparable LED wattage, but this
is understood as a trade-off for the extraordinary beam efficiency
and narrow profile. Solid construction and beefy heft contribute
to giving the INOVA T3 excellent balance
in the hand. Ideal for individuals with medium to large sized
hands, it's quite holdable by users with small hands as well.
5- One's hand appreciates the waffle patterned
texture around body section- making the otherwise slippery
anodizing manageable indeed.The body of the light easily fills
a Large (*1) sized palm with no protrusion.
6-The perfectly round profile of the light's
design allows the light to easily roll around on tables, making
a head-down stance the only reasonable way to temporarily
place it on a table.
7- The aluminum wall thickness of the battery
tube is 4.0 mm.
8- The tail and body section fit together
extremely well with a snug but smooth threading action.The
thread used in the tailcap is finer than one that you would
find on the typical tactical flashlight, making the INOVA
T3 ever so slightly slower to reload with batteries.
9- Black Hard Anodizing Type III (Matte)
on the outside and on the inside of the tailcap and body section
provide protection against corrosion.
10- The black finish minimizes reflections/glare
by day and by night
11- There is no battery rattle, which bespeaks
of tight engineering tolerances. A satisfactory 'O' ring seal
at the tail end of the body, provides shock absorption, a
snug fit and a seal against the elements- especially water.
12- Very clean lines, excellent ergonomics
and substantial toughness. It's a flashlight that's suitable
for Military/SWAT/Law enforcement and at the same time it
would more than satisfy the needs of a consumer demanding
an overbuilt yet non-military looking product,even for everyday
use. |
| Ergonomics
& Mount Options |
1- Ambidextrous. Center of balance slightly
in front of the midpoint on the body section.
2- A large palm completely surrounds the
body of the INOVA T3, with the thumb and
first fingers- naturally positioned on the front of the body
section just behind the head-portion and indexed to a transitional
bevel. Ideal for individuals with large to medium sized hands-
it's quite holdable by users with small hands as well. It
is well suited to be held using various 'tactical' grips including:
Harries Flashlight Technique as well as forward, upward and
downward pointing 'standard' flashlight hand-held modes.It
is not particularly suited to the Surefire/Rodgers hold.
3- A highly responsive Click On/Off tail-piece
switch allows for either constant or intermittent light activation-especially
with one hand.
4- A 45º anticlockwise turn of the tailcap
locks the switch, minimizing the potential for accidental
activation.
5 - No native
mounting options for firearms use are evident, though the
mid-section is gripable by clamping brackets or other improvised
and custom designed attachment solutions.
6.
The sleek styling and gipabaility of the INOVA
T3 makes it feel sure in one's hand and yet allows
it to slide with agility into a pocket or belt holster.
|
| Affordances |
1- Stowage- A .2" diameter hole drilled
into the tailcap allows the attachment of rings, and lanyards
of substantial girth.
2 - Activation-In normal
use- light emits from the front of the flashlight when activation
occurs through an inward pushing of the rubber covered tail
cap click switch . A partial (soft) de-activation prior to
'clicking' causes the light to turn Off momentarily . Once
it's fully 'On', turning the light totally 'Off' requires
a repetition of the button clicking procedure. This dual functionality
is known as a 'toggle'. Intuitive use involves the thumb or
first or second fingers of the flashlight's supporting hand-
pressing the switch while the light is held in one of various
possible grasps- or is supported by a tripod, clamp or other
support. One hand may therefore be used to activate the light
in 'full-momentary-On' -in the Harries hold for example. The
tailpiece may be turned by 45º anticlockwise into a 'lock-out'
position to prevent unintentional activation. The threading
of the INOVA T3's tailcap is precise enough
to ensure that vibration will not accidentally turn the light
On.
3-The head is permanently attached to the
body section preventing user access to the head assembly and
minimizing opportunities for the entry of moisture or debris.
4- The removable tailpiece protects the battery compartment
from the environment by a single 'O' ring plenty of threading
and a shroud that overhangs the 'O' ring. The tailswitch design
allows for factory click switch maintenance only, as it does
not invite tampering or adjustment. Battery replacement entails
the removal of the tail section from the body section-batteries
are then fed into the battery compartment in the un-common
orientation of (+)positive polarity facing the tail switch
and (-) negative polarity facing the head of the light.This
arrangement makes for a highly simple tailcap that lacks the
coiled spring contact so typical of other flashlights.The
spring in the INOVA T3 is a rather esoteric
'sprung pin' at the depth of the battery compartment. Again,
this makes for a very smooth tailcap turning experience with
less likelihood that a tailcap coil-spring may become lost
or deformed.

| Human
Factors & Usability |
1-Matte
anodizing protects a surface that is finely machined throughout
.
2-The INOVA T3 design promotes
intuitive grip focus on the region between the tailcap and
the head bevel.
3- We did not perform a 'pull' test but we
judged the combination of aggressive body texture pattern,
combined with matte anodizing to be effective mitigators against
hand slippage- especially under wet or oily conditions .
4- The Solidness, sleekness, brightness and
sturdiness of this light make it suitable for critical inspection,
law enforcement, military and security. It is additionally
suited for rough outdoors,and other rough environmental use.It's
viability in water-sports or underwater is probably very good
(untested)-due to the impressively inaccessible head as well
as superb 'O' ring sealed tailcap.
5- While aesthetics are often a secondary
consideration when compared to performance and ergonomics,
the INOVA T3 can be characterized as the
gentle person's spotlight dressed in 'black tie '.
6-The toggling push for click On/Off activation
procedure is an intuitive and fast implementation of the switch.
7- Due to a protrusion
of the rubber switch button- the light may not be stood on
its tail for ceiling bounce mode. Candle
mode is also not an option due to inaccessibility to the emitter
as well as the fact that the INOVA T3 is
intended as a specialized 'far throwing' spotlight and not
as a multipurpose general illumination tool at all.
8-The integrated emitter assembly is not
user accessible or modifiable. |
| Beam
Quality & Characteristics |
1- The proprietary and custom designed TIROS
optic used in the INOVA T3 creates a very bright
circular beam that is a spot of light surrounded by a narrow
corona that is interspersed with a series of concentric rings.These
rings are anomalies of the optical system that is used to collimate
a maximum number of photons in the forward direction. Though
noticeable at close range, they are deemed inconsequential at
the distances that the INOVA T3 seems to be
most suited to illuminate.
2- The narrow round-shaped beam is excellent
for specialized inspection nearby or for far reaching spot illumination.
3-The INOVA T3 creates a subject
illumination in a category that we've codified as an extremely
Context Exclusive Illumination Window (CIIW)
as compared with a Context Inclusive Illumination Window
(CEIW) (*5)
4- For one test, we used the INOVA
T3 to search long dark alleyways in the club district
of our neighboring city, Washington D.C. . The INOVA
T3 easily lit up the far end of a 100' long alley without
wasting any photons on the buildings that stood on either side.
The INOVA T3 was also excellent for penetrating
tinted and dirty glass and screened security grates.
5- Due to it's slightly blue biased beam corona,
the INOVA T3 exhibited some light scatter
when used for foraging on a hot humid night. The addition of
CC 10Y or 1/4 CTO filtration would help to correct this bias
and make it more effective in penetrating air laden with reflective
and refractive particles.
6- Due to it's narrow spot beam, the INOVA
T3 was deemed less suitable than lights with wider
beams for nearby foraging or searching. This is due to the fact
that concentrated bright light entering the retina directly,
drastically reduces night adaptedness, creating a black 'donut'
of poor vision around the spotlit region.
7-To test the throw of the INOVA T3,
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 with the subject area in near total darkness and
the evaluators and flashlight in a moderate level of street
sodium vapor ambient lighting (RH=50% at 65ºf). 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 feet away,
the INOVA T3 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

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 INOVA T3's color is in-consistently
around 5,500ºK from center to corona. This makes it ideal for
situations demanding very good fidelity of color differentiation.
While ideal for most uses, a beam color so blue might make it
subject to some glare if used in conditions of high water vapor
/ humidity or smoke.

| Brightness |
The INOVA T3 scored Maximum Distance
for Object Identification or MDOI at 145
feet -and did so while displaying the brightest
hotspots we've seen to date from any flashlight of its class.
The INOVA T3's brightness is more than adequate
for law enforcement, security,and specialized far-reaching
illumination tasks as well rugged outdoors use.

| Conclusions |
1- The INOVA T3
is a medium/heavy duty rough use flashlight that's ideal for
specialized flashlight tasks in a number of everyday and several
demanding applications. Due to its robust construction and
waterproofness- combined with bright beam, we judge it to
be an excellent choice for any flashlight tasks that demand
reliability and a relatively long-life emitter.
2- Longer lived than Xenon bulbs of comparable
brightness the 3 Watt Luxeon LED (10,000 Hrs) in the INOVA
T3- gives it around 10 times the life span of a flashlight
with a 5 Watt emitter with only 30% less output. A dual or
variable power setting would help preserve LED life span as
well as battery power in situations that do not require the
full force of the INOVA T3's 4 Watt LED's
output. Such a variable levels capability would also help
preserve night adaptedness for close-up situations.
3-Value. With new flashlights in the Luxeon
market space -being released frequently- it's hard to define
a relative value when comparing non-com parables. The
INOVA T3 is a very good value in a class with few
contenders. At this point in time, the INOVA T3 rates
4.5 stars out of a possible 5 stars.
Our gripes were... A) No low power option B) Cannot stand
up in Ceiling-bounce mode C) Non user accessible head section
D) Specialized optics make the light longer and heavier than
it might otherwise be E) Concentric rings in corona are a
bit distracting

(*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 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.
