Appreciate you taking measurements but IIRC Olights are also known for having cool tints, and from what i’ve read on here meters don’t always read consistently across tints so it may be that while your setup is good for cool white it may not be accurate for warm white. Is that a possibility?
Hank, does the DT8 have 2 MCPCBS and optics side by side covering 4 LEDs each or is it 1 optic and 1 MCPCB for all 8 LEDs?
I calibrate my measuring equipment with 3 professionally measured lights, at 3 different CCTs, ranging from cool to warm.
It may not be a professional integrating sphere but it is as accurate as it can get, for what it is.
That can’t be someone’s collection, that’s over $1000 bucks.
Hey Hank,
Any chance of making a variable tint version of the Emisar D4?
For variable tint, you would need 2 warm emitters and 2 cool white emitters. (probably SST-20s would work best). They would need to be on separate channels so you would likely need a custom quad star.
But apart from the star, everything else can be done with stock components. Anduril 2 comes with built-in support for variable tint lights so you can use existing firmware.
D4V2 with 4 emitters may too dim for the variable tint, I assume 10+ emitters will make much more sense.
It’s 2 optics on one single MCPCB.
I have a Sofirn IF25 which uses 2x 3000K SST20 and 2x 6000K SST20 with variable tint. It actually works quite well and is plenty bright enough. The light is just a bit big and lacks Anduril. A D4v2 with the same 4 emitters and variable tint would be perfect I think.
I still say that D18 would deserve more variants (and the corresponding driver upgrades), like this tint mixing idea, or a version with E21A emitters (2 channels of 9A driver, 1A/emitter in total, could be with no tint mixing, or with tint mixing as well).
(Bottom line: Maybe I ask way too much but somewhat bigger (more throwy) TIR optics could be also used in a 10+ emitter flashlight - but that would mean a flashlight head redesign as well).
Really? 
Just unboxed my cyan D4SV2 with those rare XP-L HI T6 8D 90CRI. Gorgeous tint, I‘m lovin‘ it. :LOVE:
Is that the 4k or 2800k?
lol! I was going to say, I feel there are dozens of members here that have very similar collections to that, or bigger.
Only $1,000? Hehe that’s just getting started for a Noctigon/Emisar addict. And there are lots of us…
2800K
How does it compares to other warm emmiters you have?
Hey Lux would you mind sharing the exact build for your new 2800K D4SV2? It sounds amazing
Can that emitter be put in a D18? Man would that be sweet
That is a gorgeous light..
ahh, dammit now I know I need to get in on one, and since I've sold all my d4s', now I just need to decide - cyan or green?? Decisions decisions...
Hi Hank, I’m prob dreaming here but is it possible to get a D18 with 18 XP-L HI T6 8D 90CRI emitters?
Send him an email and be prepared to pay $150+
