Hot off the press - courtesy of 4Sevens I have in my hot little hands a Limited Run Quark AA-Warm white.
To be clear this is a Warm tinted LED a Cree XP-G Q5 - 7A3 or 7B4 bin tint,
as opposed to the previous run of Neutral whites.
Binning sheet for the Cree XP series -
these Warm whites are in the color temperature of about 3100K (green outline)-
most people (including me) probably won't tell any difference between the two bins -
especially in any typical flashlight usage.
At about 3100K this is close to imitating a good incandescent halogen xenon light (max possible color temp = 3200K before it burns out).
(Note: the Neutral white used previously were about 4100K, bin: Q3-5A - in blue-gray circle)
This Quark AA Warm Tactical was actually an AA2 head that I moved onto a single AA body to make up a "Quark AA-Warm".
This time the yellow/brown tint of the phosphor in the emitter is more obvious - whereas the tint of the Neutral white emitter phosphor is just barely different from the cool white.
What about this fuss over the Green packaging?
well, I really like this in a reusable heavy duty zip-lock bag - that's really good thinking - far more useful than boxes that cluster up space.
So OK what is the Warm emitter like?
vs. Neutral White 4Sevens Quark AA both Max and NiMH
yes, the Warm is "warmer" more yellow than the Neutral white and it is indeed brighter - as one would expect being a Q5 flux vs. the Q3 flux of the neutral white.
vs. 4Sevens Quark AA-R5 Cool White both Max and NiMH
well, not bad at all seems close in brightness - and the Warm does look like an incandescent.
Talking about incandescent - let's compare the Quark AA Warm to a real incandescent - the now legendary and one time considered a brightness monster the SureFire 9P - mine is the real original original 9P it is a Xenon powered by 3x CR123A and rated at 105 lumens......
vs. SureFire 9P (Xenon 3x CR123A) -
I would say these were pretty comparable -
the SureFire 9P has a more intense hotspot - but that stands to reason because of the much bigger deeper reflector - but the tints in these comparison beamshots look very similar
(but note in real-life the SF 9P seems a bit paler yellow and may have a hint of green when compared side-by-side to the eye)
So for incandescent flashaholics this is close to ideal -
the color temperature of a good incandescent xenon light
but with the efficiency/runtime of LED
and now higher output and multiple levels.......
Life for flashaholics just keeps getting better.
