Form Factor & Build
|
1-Classification-
The Photon Freedom is a standard bearer or
benchmark against which most Key chain lights of less than
two inches length are currently compared. A direct descendant
from the original Photon 1 Micro it's in the top echelon of
current day squeeze lights that seem to share the same ancestor,
the Duracell Squeeze
light- a behemoth that used 2XAA batteries to power a
single LED and was designed to be disposable. While many high
quality squeeze lights currently exist, few have the quality
of build and usability of functions offered in the Photon
Freedom. In addition to being a market leader in
its niche, the Photon Freedom is offered
in many more configurations than even its nearest competitors.The
Photon Freedom and it's predecessors are also pressed into
service to fill needs often associated with full size flashlights
or specialty illumination devices.It further demonstrates
that it's possible to offer a range of users a product that
can be used by both the technologically challenged as well
as those that appreciate sophisticated microprocessor controllability
in something as basic as a key chain light. As such it crosses
the boundaries between key chain lights, markers, beacons
and special spectrum markers and inspection lights.
2- Build Quality- The Photon Freedom
is made in the USA of Glass-filled polyurethane or G10 .This
is a polymer compound that has proven its worth as a replacement
for steel and other metals in products such as handguns, medium-heavy
duty machine parts, transportation products and knife scales
to mention but a few.The use of so strong a material in the
Photon Freedom, makes it tough enough to
take beating like no other key chain light in its class. This
also means that the Photon Freedom like the
rest of the Photon Micro series will often outlast similar
products in normal everyday use. These are mass production
high quality lights that are suitable for light to medium
duty everyday or occasional use. Though featherweight, the
Photon Freedom is well made and not likely
to come apart or suffer damage from interactions with other
key chain inhabitants.By reducing the opportunity for serious
damage to just a very few regions of the product's anatomy,
the designers of the Photon Freedom have
maximized its reliability while still offering customers a
product that can indeed be opened for battery replacement.
A handy hat clip that doubles as a magnet enabled hand's free
stand is equally well built and extends the functionality
of the Photon Freedom.
3- Physical Features -Flat and squeeze friendly,
diminutive and minimalist.
The diminutive form factor of the Photon Freedom
makes it an ideal candidate for stowage where other lights
would simply not be welcome. In addition, it seems to be one
of the few products in its class that would fit comfortably
on a zipper-pull, charm bracelet, necklace or alternative
wearable jewelry application.
4- Wall Thickness- N/A
5- Finish-Black fine pebble grain textured
natural G10 polymer
6- Fit- The battery compartment cover fits
precisely in its place on the underside of the light. The
light itself fits securely into the included hat clip

& Mount Options |
1-
Laterality Dominance. The flashlight is ambidextrous
and is a true pleasure to use since it fits perfectly in the
space created when a thumb pad and finger pad meet.
2-Switch Activation At the most basic level,
the Photon Freedom is activated by simply
squeezing the flat top and bottom between a thumb and finger
until it comes on. The pressure switch is actually on only
one side ( called the top) of the light. Beyond this basic
functional model, there is a bit of a learning curve in using
the Photon Freedom.
-Lights are shipped in "demonstration" mode. To
exit this mode:
- Press and hold the switch until the light turns
off (about 20 seconds). After that you can access
all of the full use modes.
The functional interactions are as follows:
-Off -> Press and release:RESULT= ON-High
-On -> Press and release:RESULT= OFF
-To gradually dim the light from ON-High->
Firmly Press and hold: RESULT= variable dimming that can be
halted by releasing pressure on the switch
To turn off the light from any level->
Quickly Press and release:RESULT= OFF
-To gradually increase levels from a previously dimmed
level -> Press and hold: variable brightening
occurs which can be interrupted by releasing the pressure
-To enter optional blinking and SOS modes->
from ON or OFF-> squeeze light with continuous pressure
till it has passed through one dimming cycle. It will then
blink once to signal a mode change. RESULT= It will then enter
the first option of the blinking modes-> Slow flashing.
Continue pressing and it then scrolls to the next
modes Medium Fast & Fast Flashing and finally
SOS mode
- Releasing pressure at any of these settings makes them permanent
until either the battery runs out or the switch is pressed
to turn the unit OFF. To move to the next optional mode the
user simply applies firm constant pressure to the switch
- To enter momentary ON mode -> Very rapidly
squeeze the light in a series of On/Off cycles till it does
not stay on (In real terms this requires quite a bit of dexterity
in order to 'bypass' the standard switch programming- a feat
that requires lightning fast reflexes and a nimble thumb or
finger action). The light will then be constantly on high
every time it is temporarily squeezed.
- To exit momentary ON mode-> Press and
keep pressure on the switch till it finally turns Off.
Analysis- The Photon Freedom is thus designed
for two levels of user- Beginners and Experienced. For most
users , the basic functionality of ON-High / OFF is enough.
For those that need the flexibility of the advanced options,
a read of the instructions and a few minutes of practice will
generally embed the enhanced use models for special context
usage.
3- Battery Changes are effected through removal
of the 'underside' logo cap with a fingernail or small pointed
implement. Once removed, the two CR-2016 coin cell batteries
may be slid out from underneath their metal strap entrapment
and replaced with fresh ones. This last action- removing the
batteries- will likely necessitate the use of the same implement
used to get the compartment cover off. The batteries are in
so tight a space that there is nary room enough to wiggle
them out without the assistance of the aforementioned sharp
and pointed implement.
4-Loss Prevention/Stowage-A nickel plated
1cm diameter split ring and gate-clip 'lobster-claw' are furnished
in addition to the dedicated hat clip/stand /magnetic base
accessory. A generously large .25" (6.5mm) lanyard hole
may also be used instead of the supplied terminal hardware.
LRI, the manufacturer of the Photon Freedom
also offer a neck lanyard as an optional accessory.
5-Handling.Lacking any complex shapes switches
or other protrusions, the Photon Freedom
is easy to point and handles ergonomically between finger
and thumb. For hands free usage it rides between one's lips
as would a coin. Caution should be exercised as the Photon
Freedom is small enough to swallow accidentally-
making a 'mouthing' option less appetizing in the event of
careless misuse. A light this small encourages all manner
of creative attachment. For the Photon Freedom
owner the included hat clip accessory takes care of most such
needs, with the optional lanyard completing the kit.

Factors & Usability |
1-Deployment
The Photon Freedom’s form
factor and size suggest that it may be stowed and deployed
in a manner similar to other lights of this category. As is
the case with many micro lights of this type, the key chain
that hosts them is often the main 'handle' while the light
itself is simply another 'appendage'- one that also happens
to be a tool for pointing illumination. As un tethered discrete
illumination tools, they are easily deployed from cover or
stowage with the same ease that one might produce a coin nestled
in a coin pocket.
2-Changing 'States'- Focus is fixed at the
optimal beam angle produced by the emitter. The squeezing
action is the stereotypical model for such lights. The sophisticated
modes offered by the Photon Freedom do require
a read of the instructions as well as some practice for neophytes
to master. Once mastered however, the usage models become
embedded in muscle memory for quick and easy semi-intuitive
implementation. The programming of the Photon Freedom
is a significant improvement over the previous model in that
some inadvertencies have been effectively mitigated against.
In addition, by making the entire surface area of the 'control'
region active (Rather than the bifurcated switch of the Photon
III), users are more likely to affect a predictable activation
and therefore less likely to inadvertently activate the light
in an unintended manner.
3-Usage Options The Photon Freedom
is tiny enough to use as a key chain light for keyhole location
or it can be pressed into service as a highly respectable
navigation aid at distances of up to 20' in total darkness.
We discovered that these lights make excellent search tools
for fly fishing or other tackle boxes, hobby and general near
proximity foraging. Optional Photon Freedom
versions with colored or infrared / UV spectrum LEDs make
them useful tools to covert operatives as well as pilots,
CSI and military personnel.

| Conclusions |
1-Summary
Comments-The Photon Freedom is a
well crafted small production flashlight from an innovative
manufacturer. It's in the vanguard of LED key-chain lights-
not only due to it's tiny size, but also because it uses sophisticated
microprocessor control to affect a range of LED illumination
levels as well as special purpose flashing and signaling functions.
Its build quality and reliability have earned it well justified
praise and respect in a field crowded with competitors. In

Footnotes:
(*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)
(*3) Usability testing results - in progress.
(*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.
