1-Classification- The , Nuwai 0.5W is a pocket sized flashlight. The Nuwai 0.5W uses a .5Watt Ultra Bright LED powered by a single AA size battery. The Nuwai 0.5W is small enough to be carried in a pocket,pack, purse or briefcase.
2- Geometry- The light is a radially symmetrical cylinder with only a the pocket clip protruding from the side.
4- Build Quality- The Nuwai 0.5W is well made by CNC machine process. There are no sharp edges or roughness.
5- Physical Features - It looks like a diminutive flashlight, having a head that's wider than the body and tail. Progressively narrower sections give it a taperd look- not unlike the larger tactical flashlights to which it seems to pay homage.
6- Wall Thickness- The aluminum wall thickness of the battery tube is 1.5mm..
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 Nuwai 0.5W. Satisfactory 'O' ring seals at all junctions between sections provide, a snug fit and a seal against the elements- especially water. The front lens seems to be cemented to the front bezel. Threading action is sufficiently smooth.

2-Controls- in normal use, light emits from the front of the flashlight when activation occurs through a full depression and click of the round rubber button on the end of the tailpiece.Turning the light Off simply entails another click of the same switch.
3-Component/Section Accessibility The head section is threaded to the body section, allowing for easy access to the enclosed LED module or ‘sandwich’ held against the reflector with a modest retaining ring. The reflector and front lens seem to be cemented to the fron bezel. 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 entire light is water-tight to 3' as tested/

1-Deployment The Nuwai 0.5W’s construction and clip suggest that it may be stowed and deployed in a manner similar to larger tactical . The flashlightsOn/Off functionality is simple to activate follows the use model of the larger tactical lights to which it alludes.
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 tailswitch clicking action for activating/de-activating the light is standard- though the concept of depressing a button for momentary activation/deactivation in Standby 'Off' mode is a feature usually found on more sophisticated lights.
4-Usage OptionsThe Nuwai 0.5W is a light that can be carried or stowed loosely in a pocket or compartment, or it may be attched to an edge using the included clip. Furthermore, terminal hardware may be attched to the clip for tethered or even keychain carry. As such, this it highly versatile for many end-users with varied preferences for stowage. The lack of a tail-end attachment point makes it less inviting for keychain use. The great advantage of the Nuwai 0.5W is that it can be used instead bulkier lights to give a premium quality of illumination in a small form factor.

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.
