Background:



I believe the 'DQG tiny AAA' initially emerged on the Chinese flashlight forums; shoudian.com . It was put together in a small workshop by someone based in china. When a cpf member posted some photos of this light on candlepowerforums, a lot of interest developed from the non-chinese literate flashaholics.



Initially, the light was only available from taobao, which is similar to a Chinese version of ebay. Unfortunately to buy from taobao, you need to pay with a Chinese credit card. This made it extremely difficult to buy the light if you live outside of china. Thankfully, since then, a dealer for the light has emerged on cpfmarketplace.



Keep in mind, When critiquing the light, you do have to consider this is a small project with limited funding behind it.





Initial Thoughts and Impressions:



-I received the natural aluminium version of this light. The aluminium is lighter than stainless steel, but it is uncoated, so I do not have to worry about the annodisation coming off. Black and Ti-coloured, would be HA III coated.

-The build of this light feels like it lacks a bit of polish. You can see the machining marks, and there are a few sharp edges that would be nicer if they were smoothed off.



-This light is the smallest AAA light I have come across. I believe the fenix e05 and nextorch K1 come close, however both these lights only have one output and their max output is significantly less. While the specifications say it is 61.5mm, when I measure it, it is actually ~60mm when fully closed. Impressive for a AAA light! It is also thinner than some other AAA lights as well.

-The lens/optic/reflector in the DQG tiny AAA is quite different from my other AAA lights. It results in a sharply-defined large hotspot, with limited brightness to the spill. Comparing it to a preon 1 (neutral XPG R4); the preon has a smaller hotspot which is slightly less intensive. The preon has a brighter spill and a more gradual transition between the spill and hotspot.



-I do not have any instruments to measure lumen ratings accurately. However by eye, based on a ceiling bounce, the DQG tiny AAA has a similar max ouput to the preon 1. The preon 1 may be a fraction brighter, which is expected as it has an XPG-R4 (as compared to XPE-R2 in the DQG). The low mode of the DQG sits somewhere between the low and medium modes of the preon 1.



-This light is current controlled, no PWM! Love that!



-This light works as a two mode flashlight:



Fully tightened (off) - slightly loosened (high) - loosened more (low) -loosened even further (off)



I wouldn't recommend having the head loosened for off-mode. It only requires a few more turns before the head will fall off completely.



Having said that, I would try to avoid over tightening the light when turning it off. If you tighten it too hard, there is a tendency for the spring to compress the negative end of the battery. My sanyo eneloop AAA, now has a small dent on the negative terminal.



-There is a magnet at the tail end of the light. This might come in handy to stick the light to the fridge or other metal surfaces. Given a choice though, I'd rather not have it. I find some of my keychain clips/split rings get stuck to the magnet. I'd also be concerned keeping it near magnetically sensitive objects, such as credit cards or CD/DVDs.

-The lanyard/split-ring attachment is fairly thin and may be a potential weak point.

-There is a glow-in-the-dark o-ring at the head. It looks sorta funky, however, it doesn't stay glowing for very long. I would not rely on using this feature to locate it in the dark.

-The head is quite small which makes it hard to use one handed



-My sample has a hole/spot in the reflector. It would be interesting to see what the after sales support is like, on this issue...

Conclusions:



For $25 shipped the DQG tiny AAA is not an overly expensive light. The build

quality is not as good as some dedicated manufacturers, however considering its a small project with limited budget, its not too bad. The size of this light is impressive, its the smallest AAA that I can find available. That it manages to fit a driver that offer a high and low mode, makes it even more impressive.



I don't think cnqualitygoods has much more stock of the DQG tiny AAA. However keep your eyes on the cpfmarketplace (dealers corner), there is meant to be a model coming out next year with an XPG LED and updated driver.
