I thought that at first too, but then alkalines are normally good performers at such low current draws so I'm not sure why that would lower the runtime by much.

I am quite sure about my statement, 4sevens is used to write runtimes on alkalines. THe AAA alkalines still can't perform that well in such currents, it is still quite high for them.

I am expecting 2,5 hours on high in eneloop!

revo is 72.4-72.7mm (HKJ's and selfbuilt's review)
72.4 * (100-21)% = 57.2mm
DQG is 56.6mm (HKJ's review)

Preon 0: 55.8mm long 12.7mm wide 13g
DQG II: 56.6mm long 12.6mm wide 12g (spec says 57.5mm long)

Practically a tie. You'd have to tighten down the heads and line them up to tell that the Preon 0 is a mite shorter.

Using 4Sevens' specs, the Preon 0 runtime at 0.24 lumens is 120 hours -- 5 days of continuous moonlight. FWIW the Preon ReVO goes for 2.8 days at 1.5 lumens on the same battery.

The DQG II runs at 5 lumens/10 hours and 60 lumens/1 hour. Seems to me that while the Preon 0 and the DQG II are the same size, their different output levels keep them from being direct competitors. Almost like the DQG II is a good compromise between an Arc AAA, E01 or Preon 0 and something like a ReVO, Maratac or ITP AAA light.

I gotta admit, I'm really tempted to pick up a Preon 0 -- so far I've had great luck with 4Sevens products.

Re: New AAA keychain light -- Preon 0

Anyone notice the new versions of the Quarks have a min output of 1 lumen? Did they ditch the Moonlight modes?
 
Re: New AAA keychain light -- Preon 0

The purported run times are an extreme disappointment and will likely force me to look elsewhere.

I just don't understand why the run times would be that bad.

neither do their new icons (pictograms) follow the FL-1 Standard (Water Resistance, Beam Distance, Impact Resistance, Peak Beam Intensity, etc.) which Fenix was the first to print on its packages.
 
Re: New AAA keychain light -- Preon 0

I was hoping for a ReVo-like light...ah well :sigh:
 
Re: New AAA keychain light -- Preon 0

Not a ReVO replacement, but still a nice light and very, very small. Sort of a mini ReVO with just low and medium, no high output. I just pre-ordered a Preon P0. I don't know that it will knock my ReVO SS off the keychain but I'm sure I can put it to good use just the same. :0)

Happy to see 4Sevens cooking up new stuff.

Well, I like the levels and the size, and if it is reflectorless, the floody beam. I just don't like having to twist several times to get to the usable level. I understand the desire to have a <1 lumen low, and having that come on first, but how many lights have to cater to this. If it's going to, I Prefer the interface of the Thrunite Ti. But for now I'll be sticking with my E05, because this did not 'kill' it for me.

I've gotten used to twisting my ReVO SS as needed, and this one is a bit simpler so IMHO it's no big deal for me. This is not a tactical light, but I understand why ppl would want to start out on high output.

From reading the description this light *does* use a reflector, so I guess for some that's another strike against it. But it is supposed to be floody.

Cheers,

I hope you're right, let us know when you've tested and 4sevens could end up selling a lot more of these than otherwise! :)

I don't understand why most manufacturers send lights with alkaline cells in, according to ANSI you have to give the runtime/outputs with whatever batteries you package it with when sold. But if manufacturers sold them with energizer lithiums in then it would only cost them a little more and they could advertise much higher output/runtimes on the packaging, it seems well worth it from a marketing viewpoint.
 
I agree with shadeone and Mr. Walken, I'd like more knurling. I'm not crazy about the looks of the light, but I like the levels, the "floody" beam and the UI. Not a bad price point either. I was hoping for an E05 killer as opposed to an E01 killer, so I will definitely be in for one. I love my E05, but having a low level is a big plus for me.
 
swissbianco owns a copy already! he bought one at the SHOT and loves it since.
 
this looks so promising, i have an E05, and sometimes wished it has a lower mode.

but those stated runtimes are horrble, i hope its a typo. going to have to wait on its verdict before trying it out.
 
The runtimes are indeed terrible. I know nothing about making a light efficient, but I can't believe 4Sevens couldn't do better.
 
The runtimes are prob on the alkalines that the light are sold with. Ansi rules or something. I remeber something similar in anoter quark thread just after 4sevens started with ansi messurement. Everyone got conserned about the runtimes on the newest s2 versions. The new s2 versions had "less" lumens and less runtimes than the old r5. The spec said so, but in reality they just had to start following other rules to put the word "ansi" on the box i guess.
 
I hate to say this but I see nothing in this light that appeals to me. I have A Revo on two keychains and they have been fantastic lights. My wife has a Fenix E05 that I got for $5 less than this light. Maybe I'm missing the attraction of this light but it almost looks obsolete.
 
The attraction is it's size, current regulated, simple two modes. But mostly it's size. My DQG just dissapear in my keychain and i just love the size. Got lots of different aaa lights, but stopped using them all when i got my tiny DQG. I cant say that the DQG is better than my liteflux lf2xt, univex, or other lights, but it's smaller, a lot smaller. So it bumped every aaa light i got off the keychain.. It's going on a keychain so imo it's better off without (pocket eating)knurling. Im pretty shure i'll like the P0 just as mutch as i like the DQG.
 
jorn, please let us know in a detailed comparison which one you like more, the DQG or the P0. Runtimes arent very important, but the actual perceived brightness (the power to illuminate things in close and medium distance), beam pattern and tint.

maybe most of all, tint.
 
it is had some aggressive knurling (or just strips of it) just like Thrunite Ti do I'd get some


looks too slippy to operate one-handed with cold bare hand
Thrunites dig right in and easy to operate even with a dry sticky O ring
 
I already have one, I got mine at SHOT
It's a nice little light.
I ordered a whole bunch of 4sevens stuff at SHOT and it was at the house before I was. :)
