Form Factor & Build

1-Classification- The AWR-WB Nano is a 'custom' designed pinkie sized key chain pocket flashlight. It uses a 3Watt LumiLeds Luxeon LED, powered by a single AAA size 3.7V rechargeable Lithium Ion battery. The AWR-WB Nano is small enough to be carried every day on a key chain ring, loose in a pocket or attached to a tether such as a neck lanyard or to other objects.
2- Geometry- The light is a radially symmetrical cylinder with a bilaterally symmetrical Keyring attachment tail flange.
3- Build Quality- The AWR-WB Nano is precision made by CNC machine process. It is a 'Custom Production' small run product of less than 200 units. All components are hand assembled, adjusted, finished and fitted by the craftsperson himself.
4- Physical Features - It derives its aesthetic features directly from the (discontinued) ARC 1XAAA Keychain light. As such it also derives its almost uniformly cylindrical shape from the venerable MAG Solitaire- to which all such lights seem to pay cursory homage. The common characteristic of most such lights is that they look like shortened pencils and the head is barely distinguishable from the tail. In the case of the AWR-WB Nano, the head is clearly distinguishable from the tail section. The faintly knurled and polished brass of the AWR-WB Nano, give it an elegant look that one associates with a gentle person's personal tools. The heads are customized with a reflector designed and fabricated to marshall the emitted photons into a potent combination beam that is a 120º wide-angled flood of light, pierced by a narrow spot at its center. The reflector shape is hand cut by machine ,hand polished, nickle plated and then hand polished a second time for an inimitably brilliant mirror shine.
The diminutive size of the AWR-WB Nano make it a welcome inhabitant of any and all nooks on one's person- including and not limited to the ubiquitous Denim Jeans coin pocket, purses, shirt pockets, briefcases,and business as well as casual and occupational attire.
5- Wall Thickness- The wall thickness of the battery tube is 1mm.
6- Finish- Natural Polished Brass. Brass oxidizes in air and this oxide layer ( AKA Patina) protects it from corrosion- much in the same manner that coating, laquering and anodizing do.
7- Fit- There is no 'play' or rattle anywhere in the AWR-WB Nano. A substantial 'O' ring seal prevents water from entering the head and the emitter is sealed into the head assembly with Silicone (a reversable process)- further preventing the seepage of water into either the head or the battery compartment. There is no front lens.

Ergonomics & Mount Options 1- Laterality Dominance. The flashlight is ambidextrous.
2-Switch Activation The AWR-WB Nano is activated by a full and swift clockwise turning of the head against the body section. Deactivation is effected by an anti-clockwise turning of the head. There is no 'Lock Off' feature other than a substantial unscrewing of the head mitigates against accidental activation.
3- Battery Changes are effected through removal of the head from the body section-an action that can either be performed with one or both hands.
4-Loss Prevention/Stowage-A 3/32" hole is drilled through a flattened section of the tailpiece to allow for the attachment of keyrings, terminal hardware or various cords.
Affordances

1-Controls- in normal use, light emits from the front of the flashlight when activation occurs through a full clockwise turning of the head. There is about 10º of follow-through after it's fully On and before turning stops. An anticlockwise turning of the head in relation to the body conversely effects de-activation. The flashlight only has these two distinct parts. Thus the head acts as both switch as well as a cap and seal of the battery compartment.
2-Component/Section Accessibility The head section is threaded to the body section, allowing for easy access to the inside of the integrated LED module in the head. The circuitry is user adjustable through a tiny Phillips head screw to take advantage of future advances in battery formulation. This theoretically extends the practical life span of the AWR-WB Nano, synchronizing it's use of advanced circuitry with anticipated advances in battery formulation and capacity. Because the LED emitter is integrated with the circuitry in a reversable manner, the AWR-WB Nano would be relatively easy to upgrade by an enterprising user or for future upgrades by the manufacturer on a special order basis.The entire head may also be easily replaced in the unlikely event that it should become damaged , lost or obsolete.
3- Charging procedure. Because of the lithium Ion formulation of the battery used by the AWR-WB Nano, there is no need to either condition the battery ( monthly full depletion/full recharge maintenence) nor is there a need to fully deplete a battery in one sitting. As a result, a battery may be recharged at any drained level - maximum capacity being reached after the first 10 full recharge cycles. The spent battery is simply recharged by exchanging the emitter hosting head with the specialized charger head- and inserting the USB plug into either a powered USB1 port of a computer or with the optional A/C adapter- a household 110V outlet. 240v charging is also available by special order.
-A steady yellow light = Charging In Progress
-No Light = Charging Complete
-Blinking = Charger powered but not making contact with battery
The astute use of USB1 protocol or 'bus' makes the AWR-WB Nano a truly International illumination tool serving the mobile needs of the modern environmentally conscious computer user. This approach also extends the multifuntional aspect of USB lending value to the concept of convergancy, fungibility and efficiency.

NOTICE: The charging battery must be inserted with the positive 'button' end (up) contacting the charger head. Inadvertantly reversing the polarity of the battery positive end down, may permanently damage the charger head. Repair of a damaged charger through incorrect use is performed at the customer's expense.

Human Factors & Usability

See> AWR Nano Manual
1-Deployment
The AWR-WB Nano’s form factor and size suggest that it may be stowed and deployed in a manner similar to other lights of this category. As mentioned before, it stows almost anywhere. What sets this light apart from the rest of the keychain category is the fact that it's in the middle of the range of lights that may be as small as one inch long, to others that nudge the four inch mark. This makes it large enough for the biggest fingers and yet small enough to fit into the smallest of spaces.
2-Basic Use Model . The switch is at the head end rather than at the tail or on the body section.
3-Changing 'States'- Focus is fixed at the optimal beam angle produced by the matched reflector. The twisting action for activating/de-activating the light is standard for such lights.
4-Usage Options The AWR-WB Nano is tiny enough to use as a keychain light for keyhole location or it can be pressed into service as a highly respectable near to mid-distance torch. It seems to excel at several other tasks including: emergency exit, biking, walking/hiking, inspection, automotive and camping- to mention but a few. The twist head switch makes it impractical for signaling and it's 35 minutes of runtime keep it limited to numerous short duration uses or maximum duration uses of 35 minutes before depletion. The inclusion of a second battery gives it a runtime of an hour at a fraction of the weight of larger flashlights of comparable output. Naturally, the stowage of additional batteries would be advised for extended trips by the Nano when it's away from its recharging power sources.
5- Unlike some full sized tactical flashlights that use the 3W Luxeon emitter, the AWR-WB Nano is not so bright at a close range that it would wash out details or hamper darkness adaptedness. Nonetheless, the much anticipated VariNano Model (Variable Light Output Nano) will give customers the added flexibility of dialing output down to both extend battery life as well as to further preserve darkness adaptendness and allow for precise lower output selection.

Beam Quality & Characteristics 1-Beam Characteristics-The unique hand crafted and plated reflector of the AWR-WB Nano creates a circular combination beam that is a very broad flood of light pierced by a focused circular hotspot at its center. This is a typical beam ‘profile’ for high power LED emitters used in combination with parabolic reflectors. What is special about the AWR-WB Nano's reflector is that beam width and well as throw are visually controlled by the maker, essentially tailoring the reflector's polish to each emitter- thus ensuring that a custom fitted beam comes out of each customer's flashlight.
2-Color compared to 5,500ºK (Daylight) Almost perfectly neutral color- even tonality with no anomalies or chromatic gradations whatsoever. A wide uniform disc of daylight.
This makes it useful for all close-up navigation/search, critical inspection, forensics and short-term reading applications.
3. Recommended Filters - None required.
4-Context of Use The wide round-shaped beam is excellent for general searching and is bright and focused enough to create very bright direct ambient room lighting in a small to average sized room and still delivers relatively bright light through hand-held ceiling bounce mode (18'X12' white ceiling + white walls).
5-Category The AWR-WB Nano creates a subject illumination in a category that we've codified as a extremely Context Inclusive Illumination Window (CIIW) as compared with a Context Exclusive Illumination Window (CEIW) (*5)
6-Usage Scenarios. Excellent interior navigation in small / medium spaces. Respectable range for outdoor navigation and close-up searching. Any situation demanding a very bright, ultra-wide beam for 35 minutes or less duration.
7-Throw-Maximum Distance for Object Identification or MDOI-Confidently differentiate our test subject (a 3.5"X4.5"Black Wallet) from its immediate surroundings (black asphalt street), from as far away as 50 feet. This test simulated a person searching for a known object of known color/tone that may be difficult to distinguish from its surroundings in ambient light.
8-Percieved Brightness . It creates interior and close-up illumination that is currently at the highest end of output that one associates with flashlights of this size. It's much more than adequate for general searching or navigation in an emergency or for nightly tasks- though not sufficient for tasks with which larger and more powerful lights are typically associated -such as for tactical applications or emergencies of long durations . It is notably brighter than many much larger flashlights of legacy LED classes as well as legacy xenon incandescent pocket flashlights.
Conclusions 1-Sumarry Comments-The AWR-WB Nano is an excellently crafted flashlight that's ideal for high intensity close-range tasks. We judge it to be the eminent choice for the most power in its size class and give it high marks for it's use of sophisticated circuitry , rechargeable Lithium Ion batteries and flexible universal (USB) as well as AC recharging power options. To top this off , the AWR-WB Nano is upgradable to a higher quality of emitter and can take advantage of future improvements in battery technology.

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)

(*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.

Flashlight Head Circuitry- Chip custom LDO driver.. settable with accessible pot... set to the maximum capability of the battery, but with advent of more powerful batteries can be turned up higher.. current limit is about 450mA.. but new batteries with 600mA capability as around the corner and it'll just take a tiny twist to take advantage of them.
The LDO driver is 'basically' a 'constant current' driver.. but the current rises a bit while the unit warms up... this warming has a negative impact on the brightness of the LED and the increasing current and increasing heat counteract each other and when the driver is set to 400mA or less.. the driver is a 'constant BRIGHTNESS' driver.. which is unheard of in flashlight circles... the circuitry is always 'constant current'... leaving the brightness to the whimsy of the heat.

Charger Head Circuitry- Chip custom charger based on the LinearTech LTC4054 'intelligent' charger chip. It knows how to deal with a dead battery, undercharged battery, fully charged battery,with indication of power,charging and charged.

AWR-WB Nano - The name of this flashlight is derived from the maker's name- Andrew Wynn Rouse. Nano is becoming a generic designation for the smallest size available within a line of anything from semi-conductors to flashlights and more.Thus the AWR-WB Nano is the smallest light that his company currently produces.
