Features / Value: ★★★★☆
4Sevens is actually a relatively new maker on the flashlight scene, and very similar to Fenix, they specialize in high quality, foreign-made lights with long warranties. Similar to Fenix, they also tend to go with the "kitchen sink" method of feature inclusion. Quick list of the feature set of the Quark Mini AA2 (and all the Quark Minis):
-IPX-8 waterproofing
-Type 3 Hard Anodizing
-10 year Warranty
-T6061 Aircraft Aluminium build
-Dual-coated optical-grade glass lens
-Low-Med-High Modes plus "Hidden" Strobe/SOS/Beacon1/Beacon2 (you have to do two full runthroughs of the standard modes to get to the hidden modes)
-Included lanyard, batteries, spare o-rings in the package.
I'll have to apologize now as these pictures are NOT the best - my dSLR is currently off getting a much needed cleaning and these were taken with a point and shoot camera.
Anyways, some pictures:
Quick comparison picture for you - the Quark Mini is in the middle, bracketed by a Maglite 2xAAA on one side and a Maglite 2xAA on the other. As you can see, the Quark is quite compact for a 2xAA format light.
Picture of the Cree XP-G R5 Bin emitter. It is perfectly centered in the body, and rests in a rather heavily textured OP-type reflector. It does give a very nice beam.
Picture of the driver in the head. There is no reverse polarity protection, but the electrical contact was very good.
While I'm generally happy with the feature set, outside of the somewhat poor knurling on the head, there is one other caveat - the included extras in the package (which I don't have a picture of, sorry) are kind of useless outside of the spare o-rings. 4Sevens included 2xAA Duracell Alkaline batteries (yeah for my TV remote) and what is actually a pretty quality neck lanyard. Unfortunately, with batteries loaded this particular light is way too heavy to be worn around the neck. A decent belt sheath rather than the batteries and lanyard would've been much better.
Design / Build Quality: ★★★☆☆
Unfortunately, there are some issues with the design and build quality that really need to be addressed with this light, especially considering the normal price point (~$45 shipped).
The first issue is the knurling on the head of the flashlight.
Picture of the knurling on the head of the light. While it was decent, it was not spectacular and could be more "grippy". I'm going to have to take a bit off here - the somewhat slippery head and odd format of the light makes it difficult to operate one-handed.
The second issue was the the threads (two sets at head and tail) came only very lightly lubed, and extremely gritty. I ended up having to take the light apart and completely cleaning/relubing it before it stopped grinding.
The biggest issue, and one I find completely unacceptable in a light of this price point is that there is a really bad battery rattle. I tried the light with 4 sets of AA batteries - the Duracells that came with the light, a set of hi-cap Energizer standard NiMHs and two sets of LSD NiMHs (Eneloop and Rayovac Hybrid). All of them exhibited the battery rattle. 4Sevens has claimed in the past that the extra room in the battery tube is to take in to account thermal expansion of the batteries under heat, but I have a feeling that a strong spring in the tailcap portion would've nipped this problem in the bud. I tried stretching out the existing spring, but it's not strong enough, so I ended up having to add a piece of paper to the battery tube. If this were a cheaper 2xAA light (like the recently reviewed Tank TK566-3) I might not have cared so much, but as I mentioned - this light retails for three times as much. Unacceptable!
Battery Life: ★★★★★
For some reason, my cheapo multimeter didn't want to take any reliable tailcap readings, so I'm going to have to rely on the manufacturer's information for this section. 4Sevens rates their lights thusly:
180 lumens (high): 1.8 hours
35 lumens (medium): 3.6 hours
3 lumens (low): 3.4 days
These are just slightly behind the new S2 emitter numbers and if they are true, they are quite good.
Light Output: ★★★☆☆
In terms of light output, there are a couple problems to note. The actual lumens readings are very nice - 4Sevens is known to use OTF (or ANSI) readings in their lights, and as such the stated output on their webpage can generally be taken as accurate. The ratings for the R5 emitter were 180 lumens, 35 lumens and 3 lumens OTF. This is a very nice mode split.
However, there's more to light output than sheer lumens numbers. In terms of beam quality, pretty good. The heavily textured OP reflector gives a very smooth beam with a reasonably well-defined hotspot and smooth spill. The XP-G emitter in the short reflector also gives a VERY floody beam - there's little throw. If you like floody lights, well this is a good from that perspective.
The other part of output is tint and sorry for the language, but it's fucking ugly. It really is. 4Sevens has a bit of reputation for sending out greenish or blueish tinted emitters, and this one is no different. I normally wouldn't complain that much about the tint but:
1. It is noticeable since you're going to be using this light at short distances, and
2. They charge more for neutral-tint emitters, most of which are no longer available anyways. Blech. Talk about nickel and diming you to death.
Summary: ★★★☆☆
At the end of the day, I'm kind of undecided on the absolute value of this light. I got it at a pretty good discount to regular price (about 40%), but that price is no longer available except used. There are also some annoying build quality issues (rattle rattle), as well as the ugly tint to the beam. If it were still available at the price I paid, my recommendation would be whole-hearted. At it's current price point however it competes with lights such as the Fenix LD25, and I think the latter might come out ahead.
