Form Factor & Build

1-Classification- The , AT 3000L is a medium size handheld tactical flashlight. It uses a Luxeon III LED emitter powered by 3 AAA size batteries stored in a dedicated cradle in it's battery compartment.
2- Geometry- The light is a radially symmetrical cylinder.
4- Build Quality- The AT 3000L is fairly well made by CNC machine process. There is some threading roughness, and the qulaity of aluminum used is not an especially hard alloy.
5- Physical Features - It looks rather minimalist with only a modest diamond pattern knurling around the handle and on the the tailpiece. The tail section is readily identified by a slightly protruding rubber button cap. The head of the light is obvious in that it contains the lens, reflector and emiter module.
6- Wall Thickness- The aluminum wall thickness of the battery tube is 3mm.
7- Finish- Black Type II anodizing on the outside and throughout the inside. This anodizing should be effective against corrosion.
8-Fit- There is no 'play' or rattle anywhere in the AT 3000L. Satisfactory 'O' ring seals at all junctions between sections provide, a snug fit and a seal against the elements- especially water. The front lens and reflector are easily accessible by unscrewing the front bezel. Threading action is sufficiently smooth.

Ergonomics & Mount Options 1- Laterality Dominance. The flashlight is ambidextrous.
2-Switch Activation The AT 3000L allows for single-handed On/Off operation through the use of a low profile push-button tail switch. Momentary Off is activated by a slight pressing of the tailswitch when the light is On. This light may be held in any number of ordinary as well as tactical grip styles including forward, pointing up or down, Harries or Surefire/Rogers.
3 -Loss Prevention/Stowage-A nylon wrist lanyard attaches to the light with a split ring. A handsome velcro closure -nylon belt pouch is also included
Affordances

2-Controls- in normal use, light emits from the front of the flashlight when activation occurs through a either a partial or full pressing of the switch button. Operating the switch only causes the button to travel about 3mm. There is no 'lock-out' or other switch protection feature.
3-Component/Section Accessibility The front bezel section is threaded to the body section, allowing for easy access to the enclosed LED module or ‘sandwich’ . The LED module is not easily removable without tools. The reflector and front lens may be removed and the lens replaced.
4 A removable tailpiece protects the battery compartment from the environment by a single 'O' ring and allows for battery replacement. Contact pressure with the battery is furnished by a coiled spring in the tailpiece. The rubber covered pushbutton switch is totally water-tight.

Human Factors & Usability

1-Deployment- The AT 3000L’s simple geometrical shape suggest that it may be easily stowed and deployed in a manner similar to other such lights. It easily slides in and out of pockets. The flashlight'sOn/Off functionality is simple to activate and follows the use model of many similar lights of this caliber.
2-Basic Use Model . The switch is at the tail end rather than at the head.
3-Changing 'States'- Focus is fixed at the optimal beam angle produced by the matched reflector.The switch functional model is standard and since there are only three states, it's easy to learn
4-Usage Options The AT 3000L is a light that can be carried or stowed loosely in a pocket or compartment, or it may be attached to a tether through it's ring hole.

Beam Quality & Characteristics 1-Beam Characteristics-The high gloss plated parabolic reflector of the AT 3000L creates a circular combination beam that is a wide series of gradually brighter concentric bands of light, eventually pierced by a good-sized focused circular hotspot at its center. This is a sterotypical beam ‘profile’ for high power LED emitters used in combination with high gloss parabolic reflectors.
2-Color compared to 5,400ºK (Daylight) Pure, consistent and neutral white- even tonality with no anomalies or chromatic gradations. This makes it useful for navigation/search as well as forensic, tactical and and general nocturnal use- calling for a medium to bright output flashlight. Color differentiation is excellent.
3. Recommended Filters -None
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 a bright light through hand-held ceiling bounce mode (18'X12' white ceiling + white walls).
5-Ilumination Window Category The AT 3000L creates a subject illumination in a category that we've codified as a highly Context Inclusive Illumination Window (CIIW) as compared with a Context Exclusive Illumination Window (CEIW) (*5)
6-Usage Scenarios. Excellent interior navigation in medium spaces. Excellent range for outdoor navigation and medium distance searching.
7-Throw-To test the throw of the AT 3000L, 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 145 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=17% at 34ºf). 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 145 feet away, the AT 3000L positively lit up the ground 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
8-Percieved Brightness . It creates interior illumination that is currently at the medium/high end of output that one associates with flashlights of this size. It's more than adequate for general searching or navigation in an emergency and is excellent for tasks with which larger lights are typically associated -such as for tactical applications or emergencies of 3 hours or less duration or covering a very wide field or long distance. It is notably brighter than many larger flashlights of legacy LED classes as well as incandescent types.
Conclusions 1-Sumarry Comments-The AT 3000L is a decent quality flashlight that's ideal for medium-range tasks including: personal illumination, emergency, and as a back-up to larger and more powerful flashlights. We judge it to be an excellent choice for near to medium range general nocturnal activities as well as for everyday personal and occupational carry. It is built like a tank but needlessly so. The choice of a better quality of aluminum stock would allow a future iteration of the AT 3000L to be much thinner walled and therefore lighter and narrower.
2- Outstanding features:
- Looks and feels like a solid all purpose and back-up tactical light
- Exquisitly neutral LED BIN color
- A well matched reflector
- Uses an environmentally friendly and readily available battery type
3-Value. A fair but not excellent deal at the current price.
4-Areas Cited For Improvement A) Deserves better quality of raw material B) Deserves a larger lanyared hole C) Deserves to be table standable on its tail | Deserves a better quality of anodizing

3.75 Stars- Marginally Recommended

Pros= Decent fit and finish | Exceptional brightness and neutral combination beam | Uses rechargeable as well as disposable batteries |Accessible compartments | Upgrade potential | Water proof
Cons= Overweight | Will not stand on tail |Suboptimal material quality | No retail source in the US

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.
