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

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. Beam-shots

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.

(*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.
