Neutral tint Quark Turbo?

[Billy Berue]

Been away for a while, so apologies if this has been covered, but a quick search didn't turn up anything. I've seen the pre-order for the warm tint Quark Turbo. But has the Turbo ever been (or will it be) available in a neutral tint? I have several of the limited run neutral Quarks, and I'd love to replicate that same tint in a Turbo.

This may be the closest you'll have. The Neutrals were also a limited-run thing, done before the Turbo existed.

So how about the high CRI lights you've seen, MichaelW? What do you think of them? You're the first person I've read on here that seems to have a good handle on what is the biggest difference between cool, neutral and warm. Not saying others don't know as much as you, I just like the way you express it.

Personally, I disagree with you. I only have a warm Nitecore EZAA and the warm Quarks and MiNis I've ordered from 4sevens recently. I love the warms. I'd love to hear your take on the high CRI lights, though. I have a high CRI RA Clicky and it's a dream.

I put my money where my mouth is, and pre-ordered a WW Quark Mini 123. [got to keep 4sevens bankrolled lovecpf]
After playing with it for a while the other day, I flipped on my
http://www.shiningbeam.com/servlet/the-164/Romisen-RC-dsh-N3-WW-Neutral/Detail
and it looked 'pure white', and an a trusty old Inova TIROS X03 (and X02) they looked BLUE!
If I use that Romisen by itself, it looks somewhat yellow [5C bin isn't even 4000K CCT]

So yes, our [human] visual system has a wide ranging whitepoint/hue adjusting mechanism. The 'center' of this is usually neutral-white [and probably changes with age], but depends on the intensity-see Kruithof curve. But what CCT light, or better yet SPD provides the easiest workload? [I guess it depends on the task at hand]

Kind of 'funny' that HID headlights in cars, at least the OEM ones, have a CCT of about 4200K.

Now the argument is to where neutral is. Lumileds' neutral-white was 3500-4500K, but I like Cree's better; 3700K (melting point of filament) to 5000K.

and now 4sevens has a 'outdoor-white' [outdoor-white is 4000-5000K CCT] SMACK in the middle, R4 bin output 4500K CCT.
I will sell blood or other bodily fluid so I can get at least one.

Voting is done, all models that are going to be produced are already produced and have been shipping for more than a week. I love mine!

They are being produced now? Where?

This seems to contradict what David was saying in the original poll posting:

"Hi everybody!

We have been fortunate enough to get our hands on a small batch of neutral-white LEDs. This time we secured the highest bin possible - R4 flux in XP-G! I've only got a couple reels of 4C0 and 4D0, both right on the planckian/blackbody line.

We need your help determining which models will be lucky enough to receive these LEDs. We do need a minimum of 150 of each model to make this work. This will be a limited-run; once we sell out of these models, we aren't planning to make any more!

This poll will stay open until May 31st. Then, we'll close the poll and open up pre-orders for the models that are popular enough to make production. We expect production to take around two weeks, so our current ETA for shipping these models to you is June 14th."

I want one (or more)!

 

[jblackwood]

You're absolutely right, sorry about that. I thought it was just the warm run.

No worries, get your vote in!

Hmmm. It won't let me vote. Guess I need to join up? I don't know why I can't use my membership. Whatever.

I vote Quark Turbo neutral R4. If 4Sevens makes one I will definitely buy one.

I voted for the neutral 123^2 turbo. I'm new to this addiction but so far my favorite Quark is the turbo. I've ordered the warm white version (and if I'm lucky it will come today) and would like to have a neutral one as well. My other hobby is photography and I think both the warm and neutral turbos would be fantastic for light painting.
