Quick Quark Query (neutral white)

[Darkspark]

Does anybody have two or more neutral white Quarks where the colors are different? i.e. - Dusty rose v.s. light orange or yellow with a tinge of green, etc. Just what is the neutral white color supposed to be and what degree of variance is acceptable? :huh2:



...and for crying out loud i do not need one in single AA configuration, so don't even try to...:hairpull:...but, i would still like one anyway...

kgtttfhfhhffffdffhf...what the deuce? Could someone also please tell me what the hell the normal default is for font type?!?
Thank You.

You eyes decieve you not.

bear in mind that ALL the bins will have a certain amount of variation in them. Thats why a given tint bin has a range of temperatures associated with it.

I have 2 quarks, and have 4 other bare 5A emittors, and they all range every so slightly, from, a sorta of pinkish hue, to a very golden colour.

I only compared the 123 and the 123-2, the AA-2 came a day later.

I didn't notice a real difference between the two, but, as I already know that you only get 100% the same if you buy a Ralight with guaranteed tint, I don't compare anymore (unless there's one tint I can't stand). My Quarks all have a nice tint!

I got this link when I asked for teh difference of 5A and 5B, just have a look :

So then, it would be reasonable to see a hint of green around one of the hotspots? But really the green seems to disappear on the high setting...

I hardly see any green in any of mine.

THey all have a nice netral tint, and I can only tell the difference if I shine them together against a white wall. There are slight differences among them, just as there are differences among my R2 quarks.

 

[Darkspark]

No problem actually...they are still nice tints...I was mainly wondering if it was normal to be finding any green in this specific tint, that's all...thanks for the help.


Has anybody else noticed that the beam color changes on different power levels?

well observed.

Some here know the phenomena that tints of white LED tend toward green as the drive current is lowered.

This also happens on the neutral whites - so what you see is basically the lower levels - with lower drive currents - being more yellow/green.....

I tried to show this in -
Neutral White (Warm Tinted) - Quark AA2 Neutral White Comparison Review

specifically please see post #14 where I was observing the tints when compared to a NiteCore EZaaW (which use mostly Cree XR-E Q3 5B) - Quarks use XP-E Q3 5A.

Also take a look at the difference in tint with different drive currents in -

Thanks UnknownVT for validating my observations on this...it's always nice to know your not seeing things. This slight tint of green is very subtle and only is detectable when white wall hunting on the three lowest levels and doesn't seem to bother me - cause overall that mellow beam color is such a nice change...

Man, i haven't been able to stump you dudes yet!

lovecpf

isn't this tint variation in lower outputs expected?

If the quark are current and not PWM regulated like the fenixes are there SHOULD be a more pronouned tint in low modes.....

It should be expected that phosphor tint becomes more pronounced at lower current. I'm flipping through levels with my neural Quark right now and seeing it. This one becomes a darker, more "tobacco" yellow at lower modes rather than green, though.

I have 2 neutral Quarks. They are slightly varied in tint. One is a little more tan and the other a little more pink. I don't actually notice any green in either.

At the lower levels they both get darker in tint, more tobacco-like, the same as someone else said. The whites show up much better at max.

 

[UnknownVT]

Our eyes/brain shift with the way we see in different lighting and colors/tints -
so it is not surprising that we all seem to describe the tints differently -
it is dependent on the conditions -
eg: if we compared these Neutral white side-by-side with a regular cool white LED (typical bin WC) -
the cool white will appear very blue and/or the Neutral white will appear very yellow/brown/amber -
Neutral White vs. regular Cool White -

in comparison.... pretty obvious.

Here are some beamshots that help illustrate the tint shift with lower drive currents (all taken with fixed daylight white balance) - the first is the easiest to see -

4Sevens Quark 123-2 Neutral vs. Neutral White 4Sevens Quark AA both on Max remember they both use the the same LED bin Q3 5A -

it's pretty obvious that the Quark 123-2 is brighter - not surprisingly since it is driven by 2x CR123A (at 6V) vs. the 1x AA which is almost the other end of the scale at all of 1.2V.
But notice the difference in tints -
the Quark 123-2 does seem to be a kind of tobacco-y brown maybe pink tinged - just as described -
but the AA version seems to be more yellow(/green?)
this kind of stands to reason since the LED is at lower brightness, so it is being driven by a lower current.

OK one might say maybe the (wide) tint difference could be due to a wide variation in the bin?
BUT if we now compare these same Quarks on their lowest levels -

4Sevens Quark 123-2 Neutral vs. Neutral White 4Sevens Quark AA both on Minimum - level 1 - Moonlight mode -

4Sevens Quark 123-2 Neutral vs Neutral White 4Sevens Quark AA both on level 2 - Low -

Note the tints how similar they now are -
at these lowest levels BOTH the Quark AA and Quark 123-2 have shifted their tints to more yellow/green -
look especially at the edge of the hotspots to see this -
just as Darkspark described previously .......
