Hey everyone, I've got a production model of the new Quark X AA-2. This is an XM-L version of the very popular Quark series of lights. The X models have the new Cree XM-L emitters installed. This light is the Tactical UI version, and this particular light was sent to me by 4sevens for review purposes.


Click on the small thumbnail below to see the full size image of the Quark X AA-2 operators manual. Within the manual you will find all the specs for this light, including how to operate this light:






This sample was sent to me without any accessories, packaging, etc. I would expect those items to be the same as the items that usually come with the Quark XP-G models, but I can't say for sure because they weren't included for my review.

Externally the Quark X is nearly identical to the regular Quark series, with very subtle changes to the body/battery tube. The size of the engraving of the brand name (4sevens) and model name are slightly smaller on the Quark X model, and there are some minor machining differences at the point where the body/battery tube is reduced in size from the head end and tail cap end. They are very minor, aesthetic differences, and do not affect the function of the light.



These lights do have square cut threads just like all other Quark models before it, so you can mix and match parts (I've already tried and the threading is the same):









Here are some images of the Quark X compared to the Quark XP-G model:












Of course if you look at the business end of the Quark X, the emitter difference is apparent :











Now for the dyno testing .




For those of you who aren't aware, I have my own calibrated homemade integrating sphere (I have two, actually) for measuring lumen output of different lights. My sphere's have been calibrated using lights that were measured in a professional lab sphere, so my lumen results are very accurate. However, due to common variables such as temperature differences, battery charge state differences, and even differences within the components used within each and every light, you should only use my results as an example of what one sample outputs in OTF lumens. If you purchase one of these lights I'm sure the output would be similar, provided all variables are similar, but your light may not produce exactly the same output as this sample. The output could be less, the output could be more, it just depends.

Okay, now that I've got that out of the way, here are my OTF lumen results:

These were taken against my garage door with manual settings. The white balance was set to auto, but all other settings remained the same for each comparison shot.

I hope you enjoyed reading my review, and thanks for looking.

A good review! Great pictures! Thank you!
The only thing missing this lamp, it is possible to put it on the tail.

Thank you for the kind words. To answer your question, I must explain that this light is offered in two different versions...

The Quark X is available in two different user interfaces. One is called "Tactical" UI and the other is simply called "Regular" UI or more recently, it seems 4sevens has simply left the words tactical and regular out of the name. Example or new name for this light - "Quark X AA2". If you purchase the Regular UI it will come with a reverse clicky tail switch, if you purchase the Tactical UI, it will come with a forwarding clicky tail switch, which allows the light to be used momentarily (like other tactical style lights). The Tactical switch protrudes out from the tailcap itself, so the Tactical UI version cannot be used in on its tail, but the Regular UI has a tail switch that does not protrude past the tailcap so it can be used while standing on its tail.

Another difference between the Tactical UI and Regular UI is that the Tactical is programmable, while the Regular UI is not.

Hope this helps. See images below:

Excellent! So everything is much better than I expected!
In my opinion, a very promising light.
I like about him: looks, light, the ability to select the option button. And also, the ability to use accessories.
