Form Factor & Build

1- Classic hand-held flashlight form. Geometry is a radially symmetrical round cross-section/ smoothened contours, Rubber like elastomer body grip adds an accent and aids in gripability.
2- Head of Light is wider than the body & tail-piece which are the roughly same diameter.
3- The flashlight feels light weight but still has substantial heft. Its styling pays cursory homage to a late 20th Century classic- the MAG Instruments®- Mini Mag-lite®.
4-Due to it's long and narrow-diameter body it's ideal for individuals with small, medium or large sized hands. In addition its slenderness lends itself stowage and carry in accessories that accommodate any flashlight with a body diameter of 22mm.
5- One's hand easily surrounds the body section.The body of the light easily fills a Large or X-Large (*1) sized palm with some protrusion. Much more protrusion will occur with small and medium sized hands.
6- The aluminum wall thickness of the battery tube is 1.5 mm.
7- All sections fit together well with fairly smooth threading action.
8- Champaign color Type II (glossy) anodizing on the outside and inside the battery compartment offers protection against corrosion.
9- There is no battery rattle. 'O' ring seals provide some shock absorption, a snug fit and a seal against the elements- especially water.
10- A mid-length center of balance make it comfortable to hold and practical to stand on it's head. Roll prevention is afforded by the attached and removable spring pocket clip. Tail section does not allow for self supported ceiling bounce or candle modes.

Ergonomics & Mount Options 1- Ambidextrous.
2- A large palm completely surrounds the body of the, with the thumb and first or second fingers- naturally positioned on the front of the body section just behind the head-portion. In normal use, the thumb of the hand holding the light would rest behind the head with the rest of the fingers supporting from underneath.It may be hand-held in various positions including: Harries Flashlight Technique,Rodgers, forward, upward and downward pointing 'standard' flashlight hand-held modes.
3- A black polymer momentary On/Off tail switch at the very rear of the tail-piece allows for simple toggling activation of the light. A full clockwise rotation of the tailcap turns the light fully 'On'.
4- The push button momentary On switch may be used for On/Off bursts of light such might be used for signaling.
5- 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.
6-A provision for lanyard attachment is comprised of a high tensile strength wire 'Pail-handle' ring that is firmly embedded into the polymer button switch
Affordances

1- Stowage- No pouch or holster are included but the tailcap naturally invites lanyard carry.Any number of third party pouches may accomodate the Dorcy Super 1W, 2XAA.
2 - Activation- In normal use, light emits from the front of the flashlight when activation occurs through either a partial depression of the of the polymer pushbutton switch or a full clockwise rotation of the tailcap. Pushbutton activation feedback is provided through a slight resistence sensation only. De-activation is implemented via release of the momentary switch or slight anti-clockwise rotation of the tailcap.
3-The front bezel is threaded to the body section, allowing for partial disassembly of the head section . The reflector seems permanently secured to the bezel and seems not to be user servicable. A couple of 'O'rings prevent water from entering the head section and therefore protect the LED module from the environment.
4-
The removable tailpiece allows for access to the battery compartment for replacements.The battery compartment is protected from the environment by an 'O' ring .

Human Factors & Usability

1-Glossy anodizing and smoothened contours of the Dorcy Super 1W, 2XAA give the surface a luxurious look.
2-The 'Dorcy' logo is embossed into the elastomer grip.
3- We did not perform a 'pull' test but we judged that the elastomer grip around the body tube would provide fair gripability.
4- The light weight and sleekness of this light make it suitable for the home and automobile, or workshop tool box, inspection, camping and security.The head is tapered and unobtrusive - allowing for clear indexing of the front of the flashlight without causing the user any undue fatigue from either bulk or weight. It is certainly as suitable for outdoors,and semi-rough environmental uses as well as being an excellent around the house, glove box, office or workshop light.
5-The polymer momentary switch is easy to activate and this makes it ideal for most flashlight users, irrespective of the thier 'finger strength'
6- The twist tailcap switch is very intuitive to use and the cognitive model is simple and requires neither training nor memorization of complex procedures.
7- Though this flashlight is clearly aimed at being stored on a pegboard, hook or lanyard , it may just as easily find its way into a desk drawer, backpack, briefcase , toolbox or glove compartment.
8- The pushbutton tailcap could have been flattened to allow for an upright table standing posture on a flat surface.
9-The emitter module is not easily user accessible.
10- Wide retail distribution via mass retailers such as Sears Roebuck/ K-Mart makes it one other more accessible Luxeon flashlights currently on the market.

Beam Quality & Characteristics 1- The parabolic reflector of the Dorcy Super 1Watt creates a circular beam that is a small flood of light gradually focused to a circular hotspot in its center. There are no rings within the corona suggesting that reflector formula and emitter characteristics are well matched.
2- The round-shaped beam is excellent for general searching and is bright and focused enough to create ample ambient room lighting in ceiling bounce mode.
3-The Dorcy Super 1Watt creates a subject illumination in a category that we've codified as a moderately Context Inclusive Illumination Window (CEIW) as contrasted with a Context Exclusive Illumination Window (CIIW) (*5)
4- For one test, we used the Dorcy Super 1Watt in hand and walked around a darkened home. It brightly illuminated entire hallways and rooms and delivered a most respectable focus that allowed for clear identification of anything hidden in a dark pocket or beneath beds or furniture. It also faired admirably in backyard foraging. The Dorcy Super 1Watt fits well into a large pocket and may be a useful bicycle light due to fact that it may use rechargeable batteries. It was a favorite 'no guilt' flashlight around the house and campsite since it readily uses rechargeable batteries.
5- Due to a good match between reflector and emitter, it didn't shine undesirable anomalies . To it's credit, Dorcy equips the Super 1 Watt Luxeon flashlight with a very neutral color LED, making it an excellent value for entry level customers wishing to maximize their return on flashlight investment dollars.There were no color variances across the beam's profile whatsoever.
6- Clearly this is a multipurpose beam that delivers a balanced compromise between a piercing spot and broad flood, making it desirable for a wide range of uses.
7-To test the throw of the Dorcy Super 1Watt, 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 90 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=70% at 82ºf). 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 90 feet away, the Dorcy Super 1Watt 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

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 a color temperature of roughly 5,000ºK. Comparing the Dorcy Super 1W, 2XAA chart photograph with a flash (White Balance set to 'Flash') exposure of the same chart reveals no color bias. This makes it useful in most object identification situations that do not involve a high level of water vapor in the air and excellent for general color differentiation. The addition of a CC.025 Y or 1/8 CTO filter over the lens would perfectly balance the Dorcy Super 1W, 2XAA 's light with daylight. In normal use it requires no filtration whatsoever. There are no chromatic variances across the beam's profile- making it highly user friendly.

Conclusions

1- At the time of this review, we judged the Dorcy Super 1Watt to be an ideal general purpose light for individual use in a wide range of non tactical or non mission critical applications.
2- It is thoughtfully designed for a wide range of customers. It deserves to be produced in a few other colors such as neutral pewter/titanium, silver and black, in addition to the current 'Champaign' hue.
3- The improvement in bin selection of the Dorcy Super 1Watt's LED emitter over previous Luxeon flashlights is a bonus to both experienced as well as neophyte users of Luxeon LED flashlights.
4- The fact that the Dorcy Super 1Watt uses commonly available size AA batteries makes it highly accessible to users worldwide. Given the growing popularity and availability of rechargeable AA batteries, the Dorcy Super 1Watt also gets bonus points as an environmentally sustainable and responsible flashlight option. As such, it makes a perfect gift for recipients that are inclined to use rechargeable rather than disposable batteries.
5- The manufacturers of the Dorcy Super 1Watt- package the flashlight, and 2 Alkaline batteries in a 'pilferage resistant' sealed plastic display package that - makes it suitable for personal purchase. It deserves to be sold with a lanyard and /or belt pouch of some kind.
6-Value. With new flashlights in the Luxeon market space -being released weekly- it's hard to define a relative value when comparing non-comparables. At this point in time, the Dorcy Super 1Watt rates 4.25 stars out of a possible 5 stars.
Our gripes were... A) Lack of pouch/holster B) Will not stand on its tail C) Inaccessible emitter module

4.25 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 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.
