Form Factor & Build

- Classic Hand-held flashlight with radially symmetrical round cross-section.
- Head of Light is wider than the body & tail-piece which are the same diameter.
-The light has substantial heft but it doesn't feel heavy.
- The aluminum wall thickness of the battery tube, looks to be about 5mm.
- All sections fit precisely and threading action is fast & smooth.
- There is some noticeable 'battery rattle' but a substantial tail-spring should absorb any rear-axis shock if the light is fire arm mounted.

Ergonomics & Mount Options

1- Ambidextrous. Familiar feel to users of classic flashlights.
2- Hand surrounds knurled round body of (TC2)light.Body of the light fills an entire medium (*1) sized palm without protruding.TC1 is an inch shorter and ideal for smaller hands but still easily holdable by Medium hands-'forward hold' on Head section may be used - May be hand-held in various positions including: Harries Flashlight Technique, forward, upward and downward pointing 'standard' flashlight hand held modes.Fine & shallow Knurling is provided on most of the body and a knurled bezel facilitates bezel removal.
3- Nine deep, lengthwise slots on the head may aid 'indexing' as well as act as roll stops when light is rested on its side on a smooth surface.
4-This light seems to lend itself to mounting beneath a carbine or shotgun with appropriate clamping accessories
5- Due to the protrusion o f the tail switch button from the rear,candle mode is not possible
6- The conspicuous lack of a lanyard hole or ring , preclude 'hanging' this light from wrist or neck (Head mounting via a Nite-ize head band is possible)

Affordances 1-Stowage- A black cordura nylon holster with a velcro flap top closure secures and makes the light accessible with a single hand. The holster attaches to belts as wide as 9cm via heavy duty velcro and snap closure.Only vertical mounting is possible.
2- In normal use, Light exits from the head of the flashlight when its activated via a single on/off 'click' switch at the tail end. Either the thumb or first finger may be used to activate the switch with the holding hand. The switch is a Kroll type with 50% throw to momentarily activate the light for signaling and 100%throw for full on/off.Two handed operation is possible
3-The Bezel may be unscrewed to reveal the emitter module, which is mounted to the battery tube via 2 phillips head screws. The Bezel itself contains the Fraen reflector/optics & Lens assembly *It is unknown whether the optics are permanently married to the bezel or not.
Human Factors & Usability

1-A smooth finish and rounded contours makes this light a pleasure to hold. The Hard anodizing makes it feels like a cold piece of metal in ones hands.The knurling aids in indexing the body shaft while the deeper slots on the head, aid in indexing the forward position. There are no dramatic geometric features, textures,points or edges that might encourage snagging. On the negative side is the possibility that the smoothness of the finish could potentially encourage slippage under duress or under cold/wet conditions. Actual field data was not available at the time of this review.
2-The holster is a pleasure to use. With a quick upward motion, the cover flap is easily ( if noisily) disengaged from the loop that holds the light itself. The same hand may then withdraw the light and deploy it with a swift revolution of the light and subsequent activation of the click switch. *Tail switches have the disadvantage that the light must be turned in order to make the switch accessible to the thumb or first finger. head-mounted switches do not require the same motion. The advantage of the tail-mounted switch is that it requires less cognitive energy for the user to index or locate the switch. Head mounted lights can slow users down as they 'search' for the button around a blind side of the head. In addition, Tail Mounted click switches are ideal for tactical use of flashlights, since they allow for activation from the rear of the light.

Beam Quality & Characteristics

1- The beam shows a somewhat concentric series of ring section, perhaps characteristic of the optics used- which are designed to favor beam throw over smoothness or great coverage. Beam angle is a utilitarian compromise between a wide flood and a narrow spot. This Luxeon 'square' effect is most pronounced at 1 Meter and exponentially diminishes or smooth's out at greater distances- so much as to be virtually unnoticeable at 5 meters.
2- The attachment of a disc shaped piece of theatrical diffusion such Lee™ 420- LIGHT OPAL FROST over the front of the optic, greatly finished such anomalies with only a 2 or 3 % loss of light and minimal loss of throw.
3-The hot spot shows a characteristic 'squared' shape that mirrors the shape of the emitter. But it is quite slight, especially at further than 3 meters

Light Quality 1-The hue or color of the light emitted by the Vortex TC2's LED is yellowish. The TC1 had an even more Yellow/Green corona surrounding a distinctly blue hotspot . I find it easy to see by the Vortex's light when navigating the mostly white walled rooms of my home and in modified candle mode, Its easy to read and shave by as well. For general back woods foraging or walking in the dead of the darkest nights, foliage stand out and way finding is in no way disadvantaged by either the beam quality or the light's color- the yellow/green bias actually being an advantage in cutting through atmospheric mist & fog.
2-The visual experience of a light's color or 'cast' are heavily influenced by many physiological as well as environmental factors. If ambient lighting is Orange biased as in the case of a sodium vapor lit street, the light from the vortex series will seems neutral to blue by comparison. Against the backdrop of a Winter landscape with a preponderance of blue wavelength light, the vortex's light seems quite yellow. This is not a light for accurate rendition or differentiation of and between colors.

Brightness

We don't have a light meter .To test the throw of the Vortex TC series lights, we conducted a Maximum Distance for Object Identification or MDOI 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 100 feet (xxx Meters) with the subject area in near total darkness and the evaluators and flashlight in a moderate level of street sodium vapor 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 100 (xxx Meters) feet away, the Micra 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.

Conclusions 1- I've used this light in general applications such as : Walking in the woods at night (Head-mounted), digging around the darkest corners of my basement closets, signaling neighbors across the street, searching for squirrels in my attic and spotting them on my roof line at night. In all these real-world applications, the light performed fairly well- throwing a respectable beam well over 20 or 30 Meters and yet is well mannered enough to serve as a mid-range spot/flood. I was able to barely identify and differentiate between objects as far away as 35 meters (*2)
2- It's too bright for most close-up work and it benefits admirably from the addition of the aforementioned Lee™ 420- LIGHT OPAL FROST diffusion over the optic ( but under the polycarbonate lens) to smooth artifacting and color anomalies out into a more neutral color balance. Thanks to the removable bezel, the light can be used in 'bare bulb' mode for a superlatively wide 170º beam with a slightly darker patch in the center. The optic is detachable from the bezel by unscrewing (with a lens retaining ring caliper tool) the black optic backing holder. The optic and lens simply come out- allowing for replacement and interchangeability of both the optic as well as the lens.
3-Value. With new flashlights in the 2,CR123 & 1W Luxeon market space being released weekly. it's hard to decide on relative value unless all of them are tested under identical conditions by the same person or lab. Furthermore, since context of use and personal preferences are varied depending on the end-user requirements, the value of this light has to be based on budgetary and well as end-use requirements. It seems to be a functional clone of many lights already on the market - the 'Bin' of the component emitters may well be of a yellower/greener bias than whiter and therefore, more expensive Bin luxeon lights in the size & price class of the Vortex TC series.
We've award the TC1 & TC2 3.75 stars (each) out of a possible 5 stars. Our minor gripes we re... A) Not native 'candle or ceiling mode' usable. B) No lanyard attachment points. and C) Slippery surface
3.75 Stars- Recommended

Footnotes:

(*1) Medium Men's glove size- Also, a Standardized Flashlight Hand Size Metric (SFHSM)

  Small A-B = 4.5" or Shorter
  Medium A-B = 4.5"-5"
  Large A-B = 5"-6"
  X-Large A-B = 6" and Longer

(*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 weherein 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.
