Form Factor & Build
|
1-The
Mr Bulk V-I-P is an example of Bauhaus/Modern design in an
early 21st Century flashlight. Conceived as an implementation
of a user and performance centered flashlight, the Mr Bulk
V-I-P marries form to function elegantly.Its lines are typical
of the post modern industrial age sensibility. its circumferential
cooling fins and radical trident tail piece echo the desin
sensibilites of the futurists in a package that exudes understated
elegance. Under the hood its a thoroughbred of the Luxeon
flashlight class of 2004.
2- The core silhouette of the Mr
Bulk V-I-P is a bilaterally symmetrical cylinder
divided into 3 distinct sections and accented by a brighness
levels control knob. At the head it's a perfectly smooth cylinder.
The entire body is a cylindrical 'heat-sink', comprised of
a series of cooling fins separated by equidistant and circumferentially
incised grooves. The tail is also smooth and is differentiated
from the head by a trident cut fin or 'crown' . This serves
to protect the tail switch from inadvertant activation, allows
for vertical stance and adds an aesthetic flourish. The entire
surface of the cooling fins is roughened for grip by aggressive
knurling.Special editions are smooth finned and some are raw
aluminum in color.
3- Protruding unobtrusively from just behind
the head and to the very front of the body section, is a 'pinched'
dial knob that functions as a dedicated levels adjustment
control.
4- The V-I-P is a medium sized but very
lightweight flashlight that has presence in one's hand without
feeling bulky or hefty. The body of the light easily fills
a medium (*1) sized palm with no protrusion
and yet is substantial enough for the largest of hands and
compact enough for or small hands as well.
5- More notable than its modern looking
'skin', is what the Mr Bulk V-I-P lacks.
It lacks superfluity to a fault. As such it's a sublime exercise
in geometric virtuousity crafted from black anodized aluminum. |
| Ergonomics
& Mount Options |
1- Ambidextrous.
2- A small or medium palm completely surrounds
the body of the Mr
Bulk V-I-P with the thumb naturally indexing atop or behind
the levels control dial. It's ideal for small, medium and
large hands. It may be hand-held in various positions including:
Harries flashlight technique and the Rogers hold as well as
forward, upward and downward pointing 'standard' flashlight
hand-held modes.
3- Surrounded and protected from inadvertent
activation by the trident tail crown is a standard Kroll click
On/Off , momentary On tail-switch that controls constant or
intermittent light activation.
4- No native mounting options for fire arms
use are evident. This is a light that is designed to either
be handheld or placed on a flat surface for candle or ceiling
bounce- hands free illumination, and is not designed to be
weapon mounted.
5-The unique contact pattern created by the
combination of fins and aggressive knurling on the body of
the
Mr Bulk V-I-P together make for an unusually
sure grip that far surpasses minimum ergonomic requirements-
even under the most demanding of circumstances. Whether bare
handed or gloved- dry or soaking wet - perfectly clean or
oil laden - almost any hand can securely hold this flashlight
without the need for force or any grip-enhancing aids.
6- By virtue of its simplicity, the Mr
Bulk V-I-P is highly pocketable and was quite
easily inserted into a number of pouches and sheaths of suitably
sized openings. Unfortunately, the agressive knurling on the
production models is a rough abrasive and tended to wear the
fabric edges of the snug fitting nylon sheaths. Smooth surfaced
versions should not exhibit this behavior.The levels control
knob created a slightly greater width requirement but it didn't
impeded sure and comfortable deployment and stowage. Under
duress- snagging of this knob might be an issue however.
Caveat- the Mr
Bulk V-I-P seems not to be designed primarily
as a tactical flashlight but rather as a stylish high performance
personal light or even a 'table' object, that can easily be
pressed into service for a variety of real-world needs, which
could include tactical , security and law enforcement.
7- A 1/16" diameter hole drilled into
the tip of one of the trident fins allows for a ring, lanyard
or clip to be attached. This feature seems to be a cursory
afterthought since no accessory ring, lanyard or clip are
provided or discussed in the accompanying literature.
|
| Affordances |
1-
No stowage sheath or pouch are provided though a key-ring
hole is pre-drilled into one fin on the trident tail.
2- Basic activation. In
normal use, light emits from the front of the flashlight when
activation occurs either through a partial pressing of the
rubber protected tail switch button (momentary) or by completely
pressing the switch button for toggling clickOn/Off activation.
3- Variable intensity control. A separate
'pinched' control knob protruding from the body section just
behind the head allows for click-stop detent Low, Medium and
High level light settings. Lacking a visible marker or index
on either the knob or the body of the light - the user discovers
that a full clockwise turn till 'stop' sets the intensity
to the Low position (5- O'clock) and that a 40º anti-clockwise
turn of the dial knob from Low-sets it to the Medium intensity(4-
O'clock). Fully turning the knob anti-clockwise places it
on High (2- O'clock). The range of turning angle from Low
to High is approximately 90º.
4-The front head section is finely threaded
to the mid body section and the tail piece- allowing for access
to the LED module and switch mechanism . These components
seem not to require any specialized tools in order for replacements
or maintenance to be performed . The head
section is comprised of a finely machined bezel, Fraen collimating
optic,coated glass lens and sealing 'O' ring.
5- The body section is split into the battery tube
and the LED module and intensity switch mechanism respectively
. 'O' ring gaskets or seals at all joins- provide precision
fit, shock absorption and an environmental seal especially
to water -though waterproofness was not tested .
6- The removable trident fin tailpiece contains
the replaceable Kroll switch mechanism and accomodates battery
replacement .Batteries are loaded into the battery compartment
from the rear and the tailpiece is re-threaded to seal the
compartment.
7- The trident tailpiece allows for the light
to be stood vertically on a flat surface and pointed upwards
at a ceiling for 'bounce' mode illumination or for the head
to be removed and the LED exposed- creating a wide-field hemispheric
illumination.

| Human
Factors & Usability |
1.Since
light activation and intensity setting are clearly separated
controls, these actions affect separate and unrelated events
activated by ergonomically different and physically separated
components.This cognitive and interactionary model makes the
use of the Mr
Bulk V-I-P easy to learn and minimizes potential user
error through otherwise combined, overlapping or confusing
controls.
This also gives the end user complete freedom and control
of the 'state' or mode of the flashlight- irrespective of
whether it's On or Off. Functionally, this model allows for
the light to be set at one of three light intensities and
then separately turned On and Off without intensity being
affected. In addition, the light may be turned On or Off and
the intensity dial then adjusted to a desired level without
affecting the On / Off state.
Not only does this logical functionality allow for the user
to match intensity as well as On/Off state to task at hand-
but it also satisfies a cardinal heuristic of Usability- namely
that the behavior of the device be predictable by the operator
at any given moment and in the case of the intensity dial,
the current setting be easily and quickly validated- even
if only by touch.
2-As mentioned in the section on ergonomics, the
gipability of the Mr
Bulk V-I-P is tremendous. This could be more
important for some users and tasks than for others. Nonetheless,
this level of 'over-build' or redundancy, leaves little room
for complaint that the flashlight could be dropped due to
slippage from the operator's hands.
3-The same cooling fins that facilitate a
sure grip, also keep the user's hands from becoming overly
hot as a result of contact with the metal surface of the light.
Because these cooling fins dissipate heat conducted from the
emitter into the air-pockets created by the spaces between
them; they effectively divert heat from the surface of the
flashlight and thus-the operator's hand and into these gaps
instead. As such, the fins serve two technical functions and
one aesthetic one- all three, features that combine to give
the Mr
Bulk V-I-P a high usability quotient.
4- The one page instruction sheet that was
included with the light- describes the functionality of the
variable intensity switch in great detail and yet perhaps
not simply enough to be understood by the technophobic. The
writing style used for the instruction sheet is more in the
spirit of a troubleshooting 'heads-up' guide than a quick-start
or step-by-step instruction. Based on the assumption that
this is a carriage trade product for use by knowledgeable
flashlight enthusiasts- especially a tight knit cadre of enthusiasts
belonging to a famous online flashlight community; the
instruction sheet certainly 'speaks' the end user's language
and should not be too harshly judged for possibly alienating
those that are are new to specialized flashlight terminology.
6- The Mr
Bulk V-I-P's lightness and sleek form make
it ideal for almost all uses where compactness combined with
modularity and high performance are key. It would be a great
and handy asset to have in the home, office , laboratory,
studio, workshop, or even 'well dressed' law enforcement and
security end uses.
7 -We can't stress enough how well this flashlight
balances form with function while factoring in usability to
deliver a holistic package that satisfies many user requirements
without burdening the customers with undue complexity or obfuscation.
8- Another useful technology feature is the
sophisticated electronic mechanism that signals when battery
power is too low to fully deliver a High level setting. Under
such a condition, the flashlight suddenly dims and slowly
flashes in a strobing manner signaling that either the battery
needs to be replaced, or the light setting must be lowered
to Medium or Low- to match intensity to available battery
voltage.This proactive modality is the equivalent of a low
power indicator but one that does not require the user to
manually check a meter, since the stepping down behavior is
automatic and self-evident another positive usability heuristic
. The 'system' , which in this case is the circuitry- offloads
some burden of vigilance from the user/operator and carries
it onto itself instead.
9-The reinforcing feedback of the Mr
Bulk V-I-P's On/Off switch is characteristically
audible and haptically perceptible- signaling that a toggling
event has occurred. Though not the most discrete of devices,
the 'Kroll' switch leaves no doubt as to whether activation
has occured or not, a factor that is often overlooked in an
effort to minimize the clicking sound that these switches
normally make. From a logical point of view, once a bright
light has been turned on, it hardly matters that the switch
makes a clicking sound.
10-The importance to a user of matching the
intensity and angle of a light's beam to a task at hand is
great. Too much light and night vision as well as perceptual
'context' are impaired. Not enough light and subjects hidden
in dark crevices and at great distances are not easily visible.
The Mr
Bulk V-I-P's three intensities provide the
ideal levels of supplementary illumination for scenes of between
a few inches and 145 feet away from the light at the simple
turn of a dial. Furthermore, once a desired level has been
set, the flashlight will continue to deliver the set intensity
of light until the battery is not able to supply enough power.
Then only lower intensity settings may be used. This extends
the usefulness of the light even beyond the point of its brightest
setting.In addition to task and goal directed functionality,
the Mr
Bulk V-I-P promotes a conversationalist use
of disposable batteries by allowing for very long run-times
as the lowest intensity setting.
11- Modularity. The availability of several
of optional reflectors extends the capabilities of the flashlight
for specialized applications. Specifically, the branded 'Bulk
Head' and it's bigger sibling the 'Big Bulk Head' -focus the
Mr
Bulk V-I-P's beam farther and with a brighter
hotspot than the smaller optic and reflector are capable of.
An accessory body section that can use rechargeable AA batteries
instead of a disposable CR123A, makes it environmentally friendly
since rechargeables may be re-used many times over. A low
profile twist On/Off tailswitch is available that allows 'ceiling
bounce' mode but eliminates the longer trident tail piece.
This accessory switch is tapped in the center by a 1/4"X20
hole that permits numerous mounting options including tripod,
lanyard as well as attachment to anything that uses a male
1/4"X20 threaded stud.

| Beam
Quality & Characteristics |
1-
The standard Mr
Bulk V-I-P optic is a Fraen that creates a
bright squarish hotspot with little corona. An optional reflector
gives owners the flexibility of switching to a combination
beam instead. The Mr
Bulk V-I-P's optic takes the fullest advantage
of this light's output potential while the reflector is a
best-in-class accessory that deivers an efficient and smooth
combination beam- one that provides both a tactical throw
as well as excellent overall illumination.
2- The square-shaped beam from the Fraen
optic is excellent for general searching outdoors since it
creates a medium sized spot that spans several feet even at
a distance of only 30' or 40' away from the target. At a greater
distance, large areas are easily illuminated with little light
wasted in a low level corona. This optic seems not to suffer
from the 'tunnel vision' that can all too often create out
of context illumination- especially at near distances. Indoors,
it makes the Mr
Bulk V-I-P a tactical powerhouse capable of
delivering a very focused beam that can illuminate subjects
that even ordinary room lighting often can't.The Fraen focused
beam is bright and concentrated enough to create pleasant
and bright ambient room lighting through ceiling bounce mode
(18'X12' white ceiling + white walls) or in bare-bulb (candle)
mode for smooth and even180º illumination.
With it's standard optic, the Mr
Bulk V-I-P creates a subject illumination
in a category that we've codified as a Context Exclusive
Illumination Window (CEIW) as compared with a
Context Inclusive Illumination Window (CIIW) (*5)
3-Using the optional reflector instead of
the optic, the resulting beam becomes a broad and even disc
of light, pierced by a small and slightly dimmer hotspot at
the center. Such a beam is excellent for a wide range of tasks
that are not covered by either dedicated spot or totally diffused
optics or reflectors. In essence, the reflector sacrifices
a small amount of brightness at the hotspot in exchange for
a wide disc plus a piercing focus or hotspot in the
center.We would characterize such a beam as having a
highly Context Inclusive Illumination Window
(CIIW).
4-To test the throw of the Mr
Bulk V-I-P on its High setting, 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 158 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=68% at 68ºf).
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
158 feet away, the Mr
Bulk V-I-P 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
5- To evaluate it's Medium setting we used
the Mr
Bulk V-I-P to perform a range of tasks with
both the optic as well as the reflector. These tasks included
: Maximum Distance for Object Identification or MDOI
which yielded a 145' result as well
as general searching both inside a warehouse as well as in
a home and on a hiking trail.In all these scenarios the Mr
Bulk V-I-P provided a level of illumination
that exceeded minimum requirements for comfortable navigation
and clear object identification. As referenced previously,
matching the optic or reflector to the task is important to
user comfort as well as task efficiency.
6- To evaluate it's Low setting, we used
the Mr
Bulk V-I-P for tasks including: path illumination
from automobile to front door,front door keyhole search, general
indoor navigation and low-level room illumination through
ceiling-bounce.This light delivered an astonishingly useful
amount of illumination even at its Low setting. This usefulness
was based on two factors: The level of illumination and color
of light. The combined effect of neutral beam color and greater
than normal 'Low' level output resulted in this perception
of a 'bright' Low light level versus a marginally useful Low.

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 Mr
Bulk V-I-P chart photograph with a flash (White
Balance set to 'Flash') exposure of the same chart, shows a
nearly imperceptible bias to blue. This makes it useful in situations
demanding the highest fidelity color differentiation. The Mr
Bulk V-I-P is too close to Daylight to benefit
from filtration of any type. In fact, it produced the cleanest
and most neutral color beam of any light we've experienced to
date. In contrast to our prior experiences with similar lights
that have variable levels setting- the Mr
Bulk V-I-P color balance did not shift even
when Medium and Low settings were used. This is notable since
it is at the lowest setting that color shifts have the the most
significant effect on perception of colors . A fact that may
explain why vision and navigation by this light set to 'Low'
was such a pleasant experience.* Independent empirical bench
tests have measured the 'run-time' of the Mr
Bulk V-I-P set to Low- at an astonishing 86
hours +. Beam-shots

| Brightness |
The
Mr
Bulk V-I-P set on High scored a Maximum
Distance for Object Identification or MDOI at 158
feet -more than adequate for general searching,
as well as tactical applications. Using the built-in variable
intensity feature allows for accurate matching of illumination
to the prevalent ambient lighting as well as context of use.

| Conclusions |
1-
Born of the marriage between flashlight community input (Action
Design), avant guard circuit design and top quality materials
and components- the Mr
Bulk V-I-P stands in a class by itself. Judged
in absolute terms, it's the materialization of everything
that its designers specified, tempered with astute Usability
considerations as well as a cautious eye on cost containment.
2-Because it's a limited edition carriage
trade product focused on performance and styling, rather than
on mass appeal, the Mr
Bulk V-I-P can't be compared to similar products
that cater to a mass market. For the same reason, it's exempt
from necessary marketing accouterments such as elegant packaging
, slick instructions or a warranty.
3- Taking into consideration its core capabilities
together with its modularity- it provides an an example of
how all top class modern products are and should be designed.
By successfully balancing user requirements and aesthetics
together with technological and budgetary constraints, the
best in class of the 21st Century should bring us more new
and exciting products like the Mr
Bulk V-I-P.
4-Value. The Mr
Bulk V-I-P-is in a class by itself with few
peers. It's not possible to assign it a relative value when
comparing it to non-comparables. At this point in
time, the Mr
Bulk V-I-P rates 4.75 stars
out of a possible 5 stars.
Our gripes were... A) Ill-conceived lanyard/ring attachment
hole B) Overly casual instruction sheet style C)Incompletely
designed levels dial . D) No aftermarket support or documented
sales channel E) Lack of serialization in a Limited Edition
carriage trade product.

(*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.
