I’m gonna assume 4 is sunlight, since it’s closest to 5600k and will appear the most white. 3 and 2 are rather close, the colors and 3 are a bit darker/ more in shadow than 2, so I don’t know if the difference there is slightly less illumination, or the colors being washed out. The cooler tones in 2 pop a bit more though, however the darker tones in 3 are close to what the tones in 4 are. Actually now that I look at it again, the colors in 3 are close to 4, and 2 are closer to 1 (mainly the peach and the brown crayons)

I’ma go:

1st place: 4 diffused sunlight
2nd place: 3 optisolis
3rd place: 2 E21A
4th place: 1 Cree

Again though, a lot of the difference I’m seeing between 2 and 3 seems to be slight exposure difference.

I cropped them out and overlaid them in photoshop so I can swap back and forth fastly to make the comparison easier.

If we’re guessing specific emitters…

1. Cree something. Probably whatever the Jetbeam comes with. CW, green, and low-CRI.
2. Neutral, but not especially high CRI. Under 90 – could be 80. 119D or 319A.
3. High-CRI, but not the highest here. Rosy tint. 219B or E21A, most likely. Could be E17A.
4. Highest-CRI. Optisolis.

My guess is that
1 is some cree, maybe >70CRI though
2 is 219C 90CRI
3 is E21A
4 is Optisolis

I voted 1 for highest CRI, but perhaps above the BBL.

It’s really hard to see the difference on a LCD because the color reproduction is so horrible, especially on a TN panel.

I think 2 is the highest CRI. However the CCT is not the same on the 4 emitters so that makes it harder to compare. In reality, when our eyes are adjusted to the CCT, it makes less difference than what we see on the monitor.

same here … and still going on while my Apples are laying beside … nothing is better than scrolling the old style (but with Logiech’s Infinite thing) …

so, #2 for TN Facepalm

Not being a CRI “connaisseur” I voted the same #1!
I don’t know in which order I would line them up after that (maybe 1 > 2 > 4 > 3 ?), but that was my vote too!
Looking forward to see the results Wink

Hmm… The red of the crayon in pic 1 looks like typical low CRI / red deficit lighting.
But i doubted too, because the glass in pic 1 looks green as glass often does.

Hum, you may be right too!
I was looking more towards the pink crayon, not the red, and it seems more “natural” to me. Hence my vote.

Looking now at the yellow crayon on picture #1, it seems to have less yellow colour.
But my monitor may be influencing my perspective, as I noticed differences between the computer and the cellphone Sick
Also, I guess the tint of the light is (the) tricky thing here, leading to see the colours differently. I noticed than when I put the Sofirn CO1 (both colour temp) against Nichias and NW XP-G2. The first impact was the same, but going into detail the differences could be seen.

Despite, I will keep my vote on #1 and let the right correct the wrong Wink

How sure can we be this test, with side by side comparisons, isn’t also a demonstration of the aforementioned Slider effect ?

Just for fun Quiz!

Which one has the highest CRI?
Only geometry correction, NO color editing whatsoever simply RAW to JPEG conversion, 5600K WB balance

My quess, nobody would see the differences since our monitors are still limited to RGB Amoled or LED. In the real world it’s so much easier to discern.
I’ll give the answer later…. happy guessing!

OK, for those downloaded the quiz answer, here’s the password: thepasswordisthepassword

ANSWER:

1. Maukka Calibrated Convoy S2 @medium mode(Cree XML2)

CCT = 6497K
CRI = 74,8
R9 = -11,2
Duv = 0,0012

2. Maukka Calibrated BLF-348 (Nichia 219C)
CCT = 5025K
CRI = 92,5
R9 = 84,4
Duv = 0,0038

3. Jetue21a at 230mA (Nichia E21A sm503 R9080)
CCT = 5333K at 700mA
CRI = 97
R9 = 85
Duv = -0,0011 at 700mA

4. Jetusolis at 230mA (Nichia Optisolis sm503 Rfc00)
CCT = 4852K at 65mA
CRI = 99
R9 = 93
Duv = 0,002 at 65mA

My Observation:
As predicted, it’s harder than comparing R70 to R8000 or R70 to R9080. Because I used 3 LED with measured value above R9080. To make things worse I believe most people here still limited to LCD, LED, or AMOLED screen with RGB light source. Until there’s a full spectrum screen, reliable CRI proofs can’t be shared as images. Quantitative data such as Maukka’s test is the only valid reference point. In image 4, we can’t see how Optisolis makes green, blue, purple, and violet “glows” as E21A does on all red pigmented crayons (pink, orange, yellow, red, brown) because most monitors still can’t reproduce wide range cyan.
Most, including me, judge the CRI by the vividness of each colors. But it’s harder because the tint masks them all. Number 4 which was Optisolis has the most neutral tint (background) yet keeps the entire color vivid, the majority will choose it. Tint is dominant shades that covers the entire scene. Any colors will be affected by the shades.
High CRI LED will makes each color has their own personality no matter what tint/shades added on them. Easier to distinguish. This can be seen under very warm CCT such as Nichia E21A 2000K and low pressure sodium. In both cases, you will not find any white but you can easily distinguish which is which under E21A 2000K. Under LPS everything looks almost the same, sometimes false. The same goes for pink/rosy tint. You can see how everything looks reddish under E21A, blue looks darker and somewhat purple-ish.

Here’s my old picture under LPS lights. Can you tell the colors?

And this is a fresh picture using Maukka’s Jetue21a 2000K R9080:

Of course you can’t see blue violet purple etc… properly as under cool white because warm white light source even ultra high CRI such as very warm incandescent has very limited spectrum towards those colors.

Green and yellow shades relates to sickness and dizzyness for most people. Red – Orange shades relates to safety and comfort. Red/pink shades relates to cheerfulness, energy, happines, and….arousal. How about shades of blue/magenta? I find most people find it as cold and mysterious. IMHO, our brain evolved to welcome/accept positive and safe traits more readily.
We can easily adapts to different shades after a while (30+ minutes?) and find everything looks normal with time. But sudden change will confuse our brain. Test yourself by entering a room lighted in 3000K in the middle of a sunny day and you’ll get what I mean.
In above quiz E21A and XML2 were the tricksters while Optisolis was the honest one. Get a Nichia or Lumileds catalog and you will find how they tailor made LEDs to help lighting designer to trick their customers by offering different kind of spectrum sets for every needs. 219B sw45k and the likes was designed for specific target such as fresh meat in the grocery stores. But some also found it extremely good to increase baby population.

Whelp, I got fooled into thinking the Optisolis was sunlight, guess I’ll have to buy one now. The difference between Optisolis an the E21A is larger than E21A vs 219C.

Hey, but the R9 value of that 219C, is it always that high?

Almost all 219C R9050 exceeds its rating. Maukka got it from other source, not me. But my 219C sm503 R9050 also exceeded R9050. OK, the crayons will be shipped to Jerommel then.

Here’s my 219C R9050 Maukka’s test result:

I wish Optisolis is a single die LED with lower voltage. For me 6500K Jetue21a, way more versatile. I made the VR10S1-757 just for those curious with Optisolis.

I still don’t understand a thing of those test graphs…
Except for the spectrum top middle and the numbers top right…

And i have a question.
Since E17A is mentioned in the topic title, do you have them for sale?
I think a quad will fit nicely on a 3535 footprint, and still able to handle (i guesstimate) 15 Watts (?)

I only have very small numbers of E17A at the moment (sm505 R70, red, green, blue, and amber). One of my next MCPCB would be quadtrix E17A to fit 3535 class (3/6/9/12V configurable).
