* Some beamshots *
so i saw that Matt S is a winner for the give away. my name is matt s. how do i find out if im the winner of the giveaway.
one problem is that neutral is from the most recent run and is throwing the whole comparison off. that is not a good representation of a neutral white tint; too cool, too green.
it's fascinating to me how a warm white tint makes a neutral tint look cool; like how neutral makes cool look. i've never had a high cri, though. i'm tempted to try one, but i'm very hesitant at the moment. the latest NW run really threw me for a loop. now i'm all loopy.
i like flashlights.
My First two have arrived!
Will have reviews up in a day or two.
These emitters rock!
I just ordered an HCRI Preon 2 and a regular CW, which will go with my existing NW to make a complete set.
I'm looking forward to comparing the HCRI output color rendering to that of the older Warm White Quark Mini I have. I'm betting that it's red things which will show the most benefit, as deep reds are the particular color that is dominant in incandescent light, but is usually underrepresented in "fake" warm sources like LED's and CFL's. Under the latter, red things (such as the red plastic in my DMM test leads) tend to look a bit dimmer and more orangeish.
4sevens, please! Make 123^2 HCRI in tactical version! They're awesome for outdoor!
If the output of the 85 CRI LED's is 68% of the R5, then 4Sevens' website saying "The high CRI outputs will be slightly less" is misleading (155 lumens instead of 230). From the Cree literature linked to above it looks like the highest bin for 85 CRI is a Q3. I'm sure the language was copied from the neutrals, where it was true. Still, that's the price of CRI, and I think it's great that 4Sevens is making these lights available.
I've seen high CRI Cree XPGs as high as Q5. They're rare and new, brand new but there out there.
I'm not saying that's what 4Sevens is using nor does it account for the numbers but sill they are there. I could care less if these are Q2's I want no need the HCRI
Of all the things I've lost I miss my mind the most!
I can't imagine the efficiency loss is much worse than the old run warm whites. My WW Quark isa bit less powerful than the regular Quark, but not by much. Certainly not a loss that hinders its performance. And if you pointed them on high at opposite sides of the room and not side-by-side, I doubt you could tell a difference (at least R2 vs. Q5 warm).
I got my Mini AA. Tint is warmer than my SC51C.
It may "break-in", but mine has to be torqued more than my other Minis. Tightening gently like my others tends to either not light or flicker. I tried cleaning the contacts a little.
You ROCK !!!
Awesome light dude. I have found IT.
123 High CRI. Make it permanent. My other lights are obsolete.
Just got my High CRI Preon 2 in and so far I like it. It doesnt loss too many lumens over the NW Preon 2. But I'll have to play around with it tonight to see if it's a keeper or not. I'll be comparing it to the NW Preon 2 and the NW Quark X 123^2. No 47's CW lights right now (and never again from any manufacturer) but I did own a MiNi AA^2 R5 that got a lot of use so I'll comment on that too. I really miss that MiNi AA^2 but I dont miss the CW tint.
Maybe it is because I have been using the HIR headlights for such a long time that I don't remember what regular halogen bulbs look like, let alone incandescent.
So the only reference I can give to the QMiNi AA hi-CRI is, partial-tint selective yellow.
It looks nothing like the warm-white of the previous special run [peach], but I guess that is what 'correlated' means in CCT.
and the loss of lumens from the lower bin is not really noticeable.
and the threading/actuation [of QMiNi AA] is way better than the old 123.
If 4Sevens can satisfy CPF, then can please any clientele.

Just played around a bit outside and I like the NW Quark X 123^2 the best for outdoor use. The CRI takes 2nd place but it was close. The NW preon was too "cool" compared to the others outside. But for indoor use I like the NW Preon the best. Again the CRI takes 2nd place. I split my light usage 50/50 indoor/outdoor so. I think for edc the CRI will fit the bill nicely.
NW Quark X 123^2 - hiking light
High CRI Preon 2 - edc
NW Preon 2 - maybe I'll try and trade it for a NW MiNi AA^2. I just cant have two Preon 2's and I really liked the build of the MiNi AA^2 when I had it
No Beam shots tonight, it's raining .
Got my two today! Very impressed. I'll take some beam shots and put them up within the next few days.
Here are my first impressions.
Obviously the lights themselves are perfect, so I'll focus on the light coming out of them.
Side-by-side comparison of the two I got, a Mini AA and Preon 2, shows some difference in tint. While both are warm white for sure, the Preon 2's tint is more on the brown side (and I hesitate to use the word "brown" because it makes it sound like an ugly tint, which it absolutely is not). The Mini AA is more… neutral we'll call it. Not as in neutral white LED neutral, just less brown. A side-by-side of the two high CRI lights and my older run WW Quark shows that the tint of the older WW Quark is a bit pinkish, and the two newer high CRI LEDs are on the yellow side (with the Preon 2 being a bit browner, which actually puts it closer to the old Quark in tint).
Like I said, I'll try and get those beam shots up tomorrow.
But great lights!! Thanks David and company for putting up with our impatience and giving us some great products!

It was very foggy last night when I used the Preon , but these emitters performe perfect in these conditions!,they penetrated the fog easily ,much better then the 'cool'tinted lights.
This is the way to go! ,thanks 4Sevens
I think fog is like foliage, the warmer tints seem to let you see deeper into it even with less output. I think the cooler reflects more off the first object causing a "road block" that is hard to see past.
The Mini AA has a regular medium textured reflector, and the Preon 2 has a micro textured reflector more like what you would see on the older 4Sevens lights or a Surefire light.

Here are some comparisons.
From left to right (white balance set to 5,200K): Mini AA (R5), Olight T20-M (XR-E, Q5), Quark 123² Turbo (S2), Preon 2 (latest neutral run), Quark RGB (neutral white), SureFire 6P (incandescent), Preon 2 (high CRI), Mini AA (high CRI), Mini Maglite (incandescent), Quark 123² Tactical (warm white).
An HDR on the same setup (white balance set to 5,200K):
Left to right (white balance set to 5,200K): Preon 2 (high CRI), Mini AA (high CRI), Quark 123² Tactical (warm white).
I was thinking of a way to really show the tint differences between all the different warm, so I set the white balance to 3,200K. Same setup as above: Preon 2 (high CRI), Mini AA (high CRI), Quark 123² Tactical (warm white).
And here is the same shot with the saturation enhanced:
You can see that the high CRI Preon 2's tint leans towards blue, the Mini AA high CRI is slightly purplish, and the older warm white Quark 123² has a lot more yellow than the high CRI models. I think this is great to see the difference between a "warm white" LED and a " warm white high CRI" LED.
Here's the same camera setup (3,200K), with the incandescent SureFire 6p (on the right) and MiniMag thrown in (on the left):
And with increased saturation:
The lower power MiniMag is, of course, burning cooler than the higher voltage SureFire, so you'd expect the CCT to be lower, which it is. And the SureFire is pure white with a magenta tinge. So, at least of my examples, the Mini AA high CRI is the closest to what a lot of us would consider the perfect incandescent tint.

MH...excellent photos. Waiting for my hcri and wondering how it would look as compared to my warms. This was very helpful.
