In-Depth Review & Pictures:
Packaging: Nuwai N1012L comes pleasingly packaged card board box. At bottom right portion of the box, there is shining mirror like, reflective, silver metallic imprint describing light model number.

Inside the main card board box, there is molded foam container comfortably holding Nuwai N1012L flashlight and carry holster. Also included (not shown) is a single page manual having light specifications, instructions to replace battery and warnings.

Size Comparison: Pictured below From L to R:CR123 battery, Nuwai Q-100 and elder brother Nuwai N1012L. Overall the new Nuwai N1012L maintains the look and feel of highly popular Nuwai QIII line. Type III hard anodized coating of Nuwai N1012L promises to hold well in rough usage.

Another size comparison From L to R: Standard CR123, Nuwai N1012L and standard AA battery. Nuwai N1012L is about 5 times in length of CR123 battery.

Bezel Comparison: On the left is Nuwai Q101 where as on right is the Nuwai N1012L. The Nuwai N1012L employs Light Orange Peel (LOP) reflector finish where as the Q101 on left has Medium Orange Peel (MOP) reflector finish. Both have ultra clear polycarbonate lens. There are 3 crenellations on QIII of Nuwai N1012L.

Bezel, Reflector Nuwai N1012L: Let's have a closer look at the bezel of Nuwai N1012L. Luxeon Rebel 100 LED is aligned almost at center. Reflector in Nuwai N1012L built from solid Aluminium and has faceted Light Orange Peel (LOP) finish. Implementing faceted orange peel reflector addresses two major issues in light beam pattern management. Firstly, it makes the beam pattern smooth, there is a very elegant transition from hotspot to side spill. There are no rings in the beam that are usually associated with smooth reflectors. Secondly, it takes care of slight misalignment of LED and ensures good and evenly centered beam coming out of the bezel. Beam profile has distinctive hotspot and transition from hotspot to side spill well defined. Beam quality is never a problem with the combination of Luxeon Rebel and LOP based reflectors.

LED in Nuwai N1012L: You may notice that there is slight misalignment of LED. The fact is, in this picture the actual size of LED die is 1mm square and picture shows LED greatly magnified. On a 1280 pixel width 15 inch monitor, die size can be measured as 20mm, that's about 20x magnification. On screen, the LED appears to be off by about 5mm i.e. the actual LED alignment is off only by 0.25 mm. Moreover the faceted reflector takes care of this minor issue.

Body: Nuwai N1012L is built from aircraft grade Aluminium. Body is sandblasted to give a matt finish and has black type III hard coat anodizing. The built quality of Nuwai N1012L is good. The body is designed in such a way that light will not roll off. Body walls of Nuwai N1012L are relatively of good thickness indicating robust construction.

Battery tube has machined grooves that provide relatively good grip.

On the other side of body, you can see the pocket clip attached with the body. Clip has means of attaching lanyard. Light model name is printed on the pocket clip.

Tail cap houses the operating switch. The rubber boot on tail cap switch does not protrude thus allowing tail stand capability.

Components: Nuwai N1012L actually consists of three main components; head, battery tube and tail cap but the head and battery tube are glued with loctite together. Head houses LED, reflector and electronics. Battery tube can accommodate two CR123 battery or a single AW 17670 Li-ion battery. Batteries do not rattle and yet there is enough space for free battery movement. Tail cap accommodates switch with black rubber boot.

Here is the side view of Nuwai N1012L Components

Inside the battery tube of Nuwai N1012L you will notice that the positive contact is surrounded by a protective disk. At the center of the disk, positive contact wire passes from one end to the other forming a zigzag pattern. The positive contact is placed on a disk of foam and the ends are connected to the PCB. The foam in center acts as a cushion to positive terminal. If the battery is inserted wrongly i.e. negative terminal of battery towards the head end, the outer disk prevents contact to the positive wire and protects the drive circuit from burning out. In short, its Nuwai's implementation of reverse circuit protection.

Head & Battery Tube: Here is a more detailed look at head of Nuwai N1012L. The head has machined concentric grooves that provide more surface area for heat desipation.

Threads on battery tube of Nuwai N1012L are not anodized and take active participation in completion of electrical circuit. There is a O-Ring seal sitting behind the threads.

The threads are machined to perfection and we did not observe any flaws in the thread cut.

The thread type on battery tube is standard triangular threads. We did not observe any locking while putting on the tail cap. The process of unscrewing and screwing back tail cap always remained smooth. We advice you to use generous lubrication over the threads for long service life.

Tail cap: The outer side tail cap of Nuwai N1012L is anodized. Tail cap houses operating switch.

Internally switch retaining disk is built of aluminium. Thread cut on tail cap, like the battery tube, is clean. Overall construction of tail cap feels strong.

Here is a 360 view of Nuwai tail cap. Negative contact spring on Nuwai N1012L inside appears to be nickel plated steel. Bare Aluminium retaining ring screws inside tail cap holding the switch assembly.

Equipment Used: Custom built Integrating Sphere with Gossen Mavolux 5032 Class B USB Light Meter as photometer. Mavolux 5032 B USB is high precision, high accuracy and high quality light meter with conformance to DIN 5032-7 and CIE 69 standards. Utmost care has taken to ensure that the light measurements are accurate.

Note: Runtime test on standard CR123 cells was not performed as manufacturer did not include batteries in shipment.

AW 17670 Li-Ion High: The runtime for Nuwai N1012L with fully charged AW 17670 Li-Ion battery on High light output level is about 1 Hour 44 Minutes till 50%. For the first 70 minutes, the light output remains between 150 and 140 Lumens, the light tries to regulate the output. You might notice that there is a ramp up in output as soon as it tries to go below the 145 Lumen mark. But after 70 minutes, since the battery can no longer provide electrical energy, light output follows the standard Li-ion discharge curve. After 1 Hour 30 Minutes the output starts rapidly decreasing for next 20 minutes and at that moment light falls in to "Moon Mode" of about 10 Lumens. The Moon mode continues for next 20 Minutes, until batteries protection circuitry kicks in. From the runtime, we observed that although there is no super flat regulation, yet the light operates within reasonable light output of above 140 Lumens for considerably long period. Also, the light provides enough warning to user about depleting battery condition. Moon Mode confirms user that he must replace the batteries at the earliest. The light manages to provide enough duration of moon mode. This is some thing that is very desirable feature, especially when we are using the protected Li-ion type batteries.

Here is the runtime graph for Nuwai N1012L on AW AW 17670 Li-Ion battery at High light output level.

AW 17670 Li-Ion Low: The runtime for Nuwai N1012L with AW RCR123 Li-Ion on Low light output level is about 5 Hours and 24 Minutes till 50%. The light output remains in between 55 and 40 Lumens for almost 5 hours before starting to deplete. For the next two hours light continues to follow standard li-ion discharge curve. At 7 hour point, battery protection kicks in and light output suddenly drops to zero.

Here is the runtime graph for Nuwai N1012L with AW RCR123 Li-Ion on Secondary light output level.

Runtimes Conclusion: Nuwai N1012L is capable of delivering upwards of 150 Lumens for more than one and half Hours. At the same time you can switch of low output of 50 Lumens and get 5+ Hours of runtime. Both output levels are useful and light provides considerably long runtime on both the light levels. We recommend use of Rechargeable Lithium-ion cells.
