Form Factor & Build

1- This is a sleek interpretation of the classic hand-held flashlight form. Geometry is a radially symmetrical round cross-section(less switch) / smoothened contours, light diamond pattern body knurling, straight tailcap knurling and decorative grooves on the head-section.
2- The head of light is wider than the body & tail-piece which are almost the same diameter.
3- The flashlight feels has substantial heft and is one of the heaviest 1W Luxeon flashlights. Its styling pays cursory homage to the venerable silhouette of the Streamlight brand of task lights.
4-Due to its form factor, it's ideal for individuals with medium or large sized hands but is quite usable by those with small hands as well
5- One's hand easily surrounds the smooth body section.The body of the light easily fills a Large or medium (*1) sized palm with some protrusion. Much more protrusion will occur with small 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 some rattle from the battery caddy. '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 or tail. No roll prevention features are added tot he head's geometry.The wide diameter and absolutely flat tail section allows for self supported ceiling bounce or candle modes.

Ergonomics & Mount Options

1- Ambidextrous.
2- A large palm completely surrounds the body of the light, 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.The thumb would then be used to activate the rubber covered push-button switch.It may be hand-held in various positions including: Harries Flashlight Technique,forward, upward and downward pointing 'standard' flashlight hand-held modes.
3- A rubber covered Click On/Off switch at the bezel allows for simple toggling activation of the light through it's pre-programmed cycle of 'Off', Constant 'On', Flashing 'On', and Off plus momentary Off from either of the two 'On' states.
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.
5-No provision for lanyard or keyring is built in.

Affordances

1- Stowage- None provided but it may fit any number of third party manufactured pouches or holsters
2 - Activation- In normal use, light emits from the front of the flashlight when activation occurs through either full depression or a full depression of the of the rubber covered click switch. Activation feedback is provided through a distinctive haptic 'click' sensation as well as a clear 'clicking' sound. De-activation requires that the secondary flashing mode be momentarily activated, after wish the light may be turned off. There is no provision for disabling the flashing mode.
3-The front bezel is threaded to the head section, allowing for user accessibility to the emitter module enclosed in the head section . The reflector and front lens seem permanently secured to the bezel may not be intended to be user serviceable. A single 'O' ring protects the head section and LED module from the environment. The head section is threaded to the body section, exposing the contact interface between the battery caddy and the emitter capsule.
4-
The removable tailpiece allows for access to the battery compartment for removal of the battery caddy and thus replacement of batteries .The battery compartment is protected from the environment by an 'O' ring around the inside of the tailcap

Human Factors & Usability

1-Glossy anodizing and smoothened contours of the Dorcy Super 1Watt give the surface a luxurious silky feel in one's bare hands.
2-The 'Dorcy' logo is printed in white on the body section.
3- We did not perform a 'pull' test but we judged the light diamond pattern knurling of the surface of the flashlight body would provide very modest gripability. The glossiness of the anodizing may contribute to some loss of traction or gripability if used with wet or oily hands.
4- Simplicity and sleekness of this light make it suitable for the home or workshop tool box, inspection, camping,and automobile use with the flashing mode ideal for attracting attention in emergencies.The head is tapered and unobtrusive - allowing for clear indexing of the front of the flashlight. 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 toggling click switch activation procedure is sure but the inability to simply turn the light either fully 'On' or fully 'Off' without going through an extra step, may prove annoying to some
6- The switch is very intuitive to use and the cognitive model is simple and requires neither training nor memorization of complex procedures. The positioning of the switch on the head of the light rather than at the tail means that the often useful tail standing posture may be adopted for hands-free ceiling bounce illumination.This is especially viable given the wide diameter of the tailcap.
7- Though this product is clearly aimed at a general flashlight market, the inclusion of a lanyard/ring attachment point as well as a pouch would have made the challenge of protection,tethering and stowage simpler.
8-The emitter module is user accessible- allowing for some modifications or replacement of the stock emitter.
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 deep 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 are some rings within the corona suggesting that reflector formula and emitter characteristics are not as well matched as they might have been.
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.
5- Due to a poor match between reflector and emitter, it did shine some undesirable anomalies as compared with several other flashlights we've evaluated. To it's credit, Dorcy equips the Super 1 Watt Luxeon flashlight with a fairly 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- In bare-bulb mode with the bezel and optic removed, the Dorcy Super 1Watt produced a wide angle (170º) combination beam- characteristic of the type that is customarily associated with bare-bulb or 'candle' mode.
8-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 5,500ºK. Comparing the Dorcy Super 1Watt chart photograph with a flash (White Balance set to 'Flash') exposure of the same chart reveals a slight bias to cyan. This makes it useful in most object identification situations that do not involve a high level of water vapor in the air and is very good for general color differentiation. The addition of a CC.025 R or 1/8 CTO filter over the lens would perfectly balance the Dorcy Super 1Watt'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.

Brightness

The Dorcy Super 1Watt scored Maximum Distance for Object Identification or MDOI at 90 feet -more than adequate for general navigation and occasional searching. It's bright enough to be serviceable at near distances and would made an admirable security,automotive, camping or bicycling light.

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.
4- 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.
5- The fact that the Dorcy Super 1Watt uses commonly available size AAA batteries makes it highly accessible to users worldwide. Given the growing popularity and availability of rechargeable AAA 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.
6- The manufacturers of the Dorcy Super 1Watt- package the flashlight, and 3 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.
7-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 4.00 stars out of a possible 5 stars.
Our gripes were... A) Lack of lanyard/ring attachment point B) Slightly slippery surface C) Lack of pouch/holster D) non user disableable flashing mode.

4.00 Stars- Marginally 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.
