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

Light Quality 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.
