From the limited run of 4Sevens Warm White emitters -
this is the Preon 2-W (2xAAA Cree XP-G Q5 7A or 7B bin).
This is from the same run as
4Sevens Quark AA-Warm Comparison Review
see that review for more details of the chromaticity binning etc of this warm white emitter.
the Preon 2 is a 2xAAA "penlight"
one can recognize the warm white emitters by the more orange-yellow coloring in the reflections.
These warm white emitters are centered around color temperature of about 3100degK - which makes them imitate/mimic a good xenon lithium light like the SureFire 6P, Streamlight Scorpion etc - it's just that this diminutive AAA penlight is more than twice as bright on max, and has three handy levels of light.
vs. Preon 2-R5 Cool White (see 4Sevens Preon 1 (1xAAA) ) both max and NiMH
well the R5 cool white is brighter but it is shown to be quite blue in comparison - while obviously the Warm looks amber.
vs. 4Sevens Quark AA-Warm both Max and NiMH
of course the Preon 2-W is brighter - stands to reason as it's driven by 3V of 2xAAA vs. the 1.5V of the Quark AA - but after I took this series of beamshots I realized I should have compared the Quark on 2xAA - so here it is:
vs. Quark AA2-Warm White - both Max and NiMH
now the Quark Warm White head on 2x AA is brighter.......
vs Neutral White 4Sevens Quark AA both Max and NiMH
the Preon 2-Warm is obviously brighter - again I should have compared the Quark NW on 2xAA as well - but this is enough to show the tint difference and if one wants more comparisons see the 4Sevens Quark AA-Warm Comparison Review.
EDIT to ADD - seems silly to talk about what I should have done, and not do it....
So here is the comparison -
vs. Quark AA2 Neutral White (Q3-5A3) both max and NiMH
now that Quark Neutral White head is brighter on 2x AA NiMH
Preon 2W medium level vs. Streamlight Scorpion Xenon 2x CR123
the medium level of the Preon 2-W was better for comparing the tints even if it is rated at only 22 lumens whereas most know the Scorpion is a real 60 lumens - the Preon 2 has a much more concentrated/narrower side-spill making that part brighter - whereas the Scorpion has a very wide (wonderful) side-spill and brighter hotspot in comparison.
The tints look similar - although in real life I see more pale straw yellow as the Scorpion's beam with a tiny hint of green - again please see Post #8 (link) in 4Sevens Quark AA-Warm Comparison Review for a discussion of the limitations of the beamshots in their ability to capture this difference that I can see.
Preon 2-W on Low vs. 2AA MiniMag krypton 2x AA Alkaline.
krypton lights are a bit warmer than xenon bulbs - and the beamshot does show the MiniMag being a bit more red - and this time the warm white emitter seems to have a tiny hint of green in comparison - this set of shots looks about the same as I see it.
The Preon 2-Warm is a handy little light and if the early feedback is any indication - seems destined for use by savvy medial personnel in place of their traditional medical incandescent penlights.
