High CRI leds, comparing R9 values, XP-G3 N219c N218b XM-L2 XP-L2

@Tjohn

Color Rendering Index is an average value based on R1 to R8. R9 is one of the six saturated test colors not utilized in calculating CRI.
…
The Color Rendering Index metric is divided into 14 color ranges from R1 to R14. Color Rendition Index is an average value based on color ranges R1 to R8 of the metric, however, doesn’t consider the remaining six extra color references. A high CRI, matched with a high R9 value yields the most precise display of color

Thank You!
I did not know those details. It explains how Yellow/Green tinted Zebras qualify as High CRI while still having rather Low R9.

High R9 for the Win!

George Yo (Mr. Zebralight), has said (in posts included in other forums) he reserved the ‘n’ for inclusion as a suffix for his model numbers long ago, but was unhappy with Nichia’s previous method of binning either above, or below the ANSI BBL, instead of centered on it.

George has however, stated his personal dislike for the trademark Nichia rose hue, to nobody’s surprise.

Curious to imagine, with ZL’s previous use of Rebel emitters, anybody is going to get in a twit over sharing a miniscule slice of sales enough to compromise a business relationship (maybe a fact of life in Russia?).

I could meet some fake sellers with “zebralight” name. Somebody register them, and yes seems that they can be blocked by request. There was several accounts with *fire cell set.
I dont believe in ZL owner tint preferences. Nichia leds have another quality level, neverless tint or cri. Leds are always clean, perfectly centered, electrical properties range is very slim. But who wants to deal with them, if they dont provide whosale discount while another company can make unbeatable offer?

What about R12? Only the Oslon Square 3000K 95CRI goes above 80 points in that metric:

Cheers ^:)

Indeed the r12 is better than the 219b r9080 sw40

That ugly green Oslon has nothing on the E21A

Oh man that’s crazy great. Have you had a chance to test anymore? I tried the 6500k and it is stunning. Have a 2000k and 3000/4000 mix in the wings but need a host. These E21As are great.

Optisolis anyone?

wow Optisol

A few more for you jon,

Completely different model Osram Oslon Square. 96 typical CRI. These will fit anywhere a Nichia 219 will

In the midst of a computer upgrade so not all software is reinstalled yet but here are the bins. Both emitters are guaranteed to be below the BBL:

those look great!
all bars are above 90
whats not to like?
assuming the tint is not above the BBL, they look like winners

[The_Driver1 (The_Driver)]

Usually only the the Osram LEDs with 3500K and below have a good tint. The more neutral white ones have a more yellow tint.

Wow guaranteed below BBL and all bars above 90 seems to suggest this will be the king of good tint/cri emitters. Where do you buy these emitters? How does it perform besides tint and cri?

seems there are factors relating to different models of those LEDs, not sure

[BlueSwordM]

Do any of you, except perhaps for Maukka, have the Samsung LH351Bs 3000k R9070?

Would like to see some data on it.

[staticx57]

Jon, here is the binning for the 3000k Oslon tested. Not good, still trying to learn Osram’s naming schemes for these products to see which generation fits in where.

Those leds are great, of that (old first gen. Square) type I have a 3500K 80CRI led in a copper AA Maratac and the tint and beam are wonderful. They knew their tints back then.

Mind though that the ebay seller shows a 2nd generation Square in the picture while the type-nrs for sale are the older and worse performing first generation Square (but with that wonderful tint). With the second gen. Square came the green-ish tints in the high CRI versions.

I like that!

@staticx57

Jon, here is the binning for the 3000k Oslon tested. Not good

darn, so, in general they could be above or below, but if you can specifically buy 6q and 6u, then its a win

now Im confused again, are you saying the LEDs that staticx57 linked have green tint? Doesnt the specific bin they list guarantee the tint will be below the BBL?

Im much more interested in High CRI than High brightness.

and please, lets only talk about High CRI, and skip the 80 cri discussion here. I want to stay focused on LEDs with High R9 values, not just high CRI values, and not LEDs with less than 90 CRI and less than R9 values of at least 80.

so far, my pick would be a Nichia sw40 9080… costs less than Oslon, and the tint bin is not above bbl
