I get this e-mail from 4Sevens saying he has one of each of the 4 Quarks for me to look at.

Before he's pressed the send button - I was knocking on his door :D

First thing I noticed was the packaging - WoW! what a great impression - the boxes were in an almost mole-skin/suede like matte black material.

There's a flap that's held closed actually by 2 magnets - to open up to a gatefold - revealing the flashlight.

In the box is an inner packaging - which means things don't just fall out of the box - they all are in place and easy to access (and even re-package) -

I'm impressed with this level of detail - even in the packaging.

A couple of shots of the Quark Series -

This comparison review is of the Quark AA - single AA model -

The 4Sevens Quark series is using the Cree XP-E R2 LED emitters.

More attention to detail - the threads on the Quark series are square cut both for better fit and less chance of mangling from cross-threading..... nice.

How does it compare?

vs. NiteCore D10 -Q5 both max NiMH

QuarkAA_D10U2.jpg

No, despite the Quark AA using a Cree XP-E R2 it is not as bright as the NiteCore D10-Q5 rated at 130 lumens - well, checking the Quark AA specs - it is rated at 90 lumens Max - perhaps 4Sevens has chosen to have a more conservative output for better life and runtime?

vs. Fenix LD10 both Max NiMH

Again not as bright as the Fenix LD10-Q5 (rated at 120 lumens).

BUT the one thing to notice is the beam - how artifact free the Quark seems -
this is due to self-centering of the LED to reflector - there is a special plastic piece that self-centers the LED dome to the reflector - very clever and effective. The beam is also much wider than either the Fenix or NiteCore which makes it perhaps more useful indoors......

How about the Minimum Low?
Quark's specs boasts 0.2 lumens - that's as lower than the NiteCore D10/EX10 that use high frequency PWM to get as low as 3 lumens -

vs. NiteCore D10 Min NiMH -

The Quark AA is definitely lower on Min than the NireCore D10's already examplary minimum low - this is really good for a quick close shot of light without disturbing anyone - and it is great to be the first level On.

All in all a pretty spectacular introduction - great attention to detail - really nice artifact free beam (due to clever self centering).

More to come on comparison of the lower levels.

Wow great to see comparison to a Nitecore D10. I love the tint on my Nitecore. I think I will still prefer the Nitecore cooler tint, but the main reason I bought the Quark is the low low. Seriously.

Nice first impression thanks. Can you do a beam comparison with the 2xcr123 against a PD30 or PD20. Also it looks like the holster is similar to a older Fenix holster is that correct.

I really don't need one nor am very exited about these light's but because its 4sevens I almost feel obligated to give one a shot.

Very nice! Imagine that: 4Sevens sells and knows a lot of brands, including the best ones around nowadays. They acquired the knowledge about what to do and what NOT to do with a flashlight. I bet these Quarks have only the best aspects of all the good brands. Besides that, they know what flashaholics like to have.

Vincent, can you post some specs about them? Lumens, modes, operation style, runtimes? Outdoor beamshots? I know, I'm asking too much, but we can't wait! :popcorn:

Can you run them on 14500 batts and compare...that I believe, might be where we see the Quark shine. Like the super wide beam. And the packaging...fit for fine perfume.

Thank you for a very quick "comparison review". The size comparison with the D10 is revealing. I prefer compact and practical lights. I'll be sticking to my D10 for now :whistle:

Thanks for the feedback -
I agree the low-low of the Quark is very useful.

One thing to note though -
notice in the side-by-side comparison beamshots when on Max how close the tints of the Quark AA and the Nitecore D10 are?

It's only on low that the Quark AA goes a bit more yellow-green - this is normally the case with regulated flashlights - the LED seems to go toward yellow-green with lower drive current. Whereas the D10 uses PWM (high frequency) to get to its low level - and the tint remains basically unchanged.

This i me hoping the review for the 1 x CR123a is next...:D

thats indeed a much lower low, which is good! would you say that the low is really truly indeed 0.2 lumens?

I went ahead a ordered a 123x2 overnight delivery so I can get it by the weekend. I love the XP-E thanks to Eagletac and like the color of the finish on the nitecore and this looks similar. Since this light is 190 OTF I am thinking it will be as bright as my PD30 and hopefully will be some more throw.

So the color of the finish the accessories, and the XP-E R2 pushed me over. Oh yeh the 10 year warranty to. I couldn't be left wondering what if while the rest of you enjoy it.

Great stuff !

It's really nice to see these lights "in the flesh" and on time - no vapourware here !

Any chance of a close-up of the perfectly-aligned LED ?
