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

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.

2700k: 7 pieces OSRAM OSLON Square | 2700K | LED 3030 | CRI 96 | 2W | LCW CQAR.CC | eBay
3500k: https://www.ebay.com/itm/7-pieces-OSRAM-OSLON-Square-LED-3500K-CRI-96-2W-HIGH-POWER-3030-LCW-CQAR-CC/282084772891?hash=item41ad900c1b:g:APAAAOSwTqdZrJYD

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!
.

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

Here is the 3000k I tested. It is a different generation of Square.

thanks for clarifying gen1 and gen2

so the ones you posted in post 55 are gen1 (all bars above 90)

and the one barkuti posted in post 49 is gen2? (all bars below 90 except green)

my confusion relates to which post has which generation, and which ebay link goes with the one barkuti posted, and which ebay link is like the one maukka calls the green one, gen2?

green lantern tangent
it seems any time an LED is manufactured to be more efficient (bright), it is also greener
as if brighter and greener go hand in hand
I see this with the N219c also, it is brighter and greener
many people dont notice green tint, especially if their eyes are daylight adapted at the time

sometimes it sucks to be a snob, it made me not want the S1 Mini High CRI, cause I saw maukkas green tint photos, and they are true in real life too, when my brain is adapted to incandescent… Lee minus green filters for the Win!:slight_smile: I dont mind trading lumens for Tint

Oops please translate U6 as 6U and Q6 as 6Q in the pictures, mixed up the order

Outstanding! Thank you very much
the green tinted gen2 version has the tallest green bar, and the green bar is taller than the R9

the gen1 binned below the BBL have R9 bars that are taller than the green bars
excellent info

I still think a taller Green bar than R9 bar is predictive of green tint, but I do realize they are separate factors. I just like rules of thumb. Pass on the Taller Green Bar for night use. During the day, my brain white balances to a lot more green content.

It think the overall spectral emission balance versus the equivalent temperature correlated black body/sun illuminant gives out the tint, and it may be well possible to hint it just looking at the balance between the saturated colour values R9 - R12:

This one should look very slightly greenish.

In this case the above one looks to be slightly below BBL and cozy, while the latter is quite balanced.

Cheers ^:)

yes, thanks for your comments,
I think saturated color balance is a potentially helpful tint hint
and I think youre correct to include the blue in a balance comparison

heads up, Clemence has a new shipment of Optisolis, N219b, E21a

here is a glimpse of past charts



.

and look what Clemence did to one of my Utorch S1 Mini…

he installed an E21A 2000k on left, plus other beam magic, compare to stock XPL 4000k on right…

watch his site and or message him for more info https://www.virence.com/shop
he offers quad boards, led reflow services, and does mods too… the man is an Artiste, Im a fan

I love the candlelight 2000k E21A. Clemence is modding several Tiara Pros with different E21A tints for me. I can’t wait to see them in action!

That 219b 4500 looks gorgeous! It's my PERFECT tint.

the 2000k looks like you smashed a pumpkin up against the wall :disappointed:

I look forward to your photos
so far I have one Utorch w 2000k E21A, and one Utorch w N219b 4500k
theres one more torch to do, and Im waffling, trying to decide what LED to choose

at first I wanted a 4000k 219b 9080, then I considered and E21A, also in 4000k, Then I decided to get another N219b 4500k 9080… the LED going into the $1000 Titanium HDS… its like the holy grail…, but I digress, then I wondered about a 5000k Optisolis…

then I posted the above comparo of the 3k Optisolis and 3K E21A… I have not yet learned if the Optisolis would fit a Utorch S1 Mini…

meanwhile I bought a Low CRI light… true story… incoming RRT-01, the polar opposite of everything this thread is about, it has negative R9, green Tint, is cool white, and makes skin look dead… but hey, its got a magnetic ring Im curious to try :-)…

see all that green in the middle of the beam? Only a snob would notice, but who knows, maybe a Lee 1/2 minus green filter will make it fun as a nightlight… at sublumen levels, colors become rather subLuminated… :wink:
(who am I kidding… I wonder if Clemence could put an Optisolis in an RRT-01;-))

Ive been using them a lot lately, its a fun LED, bright, daylight white, and lots of extra pink:

the Utorch took almost a 50% hit in lumens from the N219b swap, but Im fine with that:

Yes, I Love the Candle color option, for late night chill sessions
have another hit of Clemence’s Magical E21A 2000k:

Wow, that’s like the Hitler of flashlights…

Jon_slider, thanks for those very useful pics. I really like the magnetic rotary brightness control on the Jetbeam RRT-01. If only it has USB recharge, it would be the perfect gift light for muggles (after a HI CRI swap ofcourse).

The 4500k 219B on the right seems a bit too magenta instead of pink. the 4500k 219B in the middle seems fine. Why is that?

I think I’m going to use the E21A 2000k while watching TV. It’ll allow me to see my surrounding while not enough to distract me from the screen.

my solution to USB charging is to buy 16340 cells like Olight and Utorch, and Klarus, are including in their S1 Mini and Mi1c. The USB rechargeable 16340 is also available with a Fenix label:

The RRT-01 is actually also 18350 compatible, though those dont come w USB, I have chargers for that option.

I do find the sw45 are very “violet”, not just pink. At first I did not like them, but when Im adapted to daylight, I dont notice the violet much.

Comparing the 219b SW40 9080 and the 219b SW45 9080, I find the sw40 slightly more yellow than I like… but Im very nit picky at this level of detail. The sw45 is bluer and pinker, but also cooler CCT, and there are times when I like cooler CCT

atm my use of sw40 has decreased, and my use of sw45 has increased.

Since I already have a Utorch S1 Mini w 2000k E21A, and another Utorch S1 Mini w N219b sw45, Im pondering what LED to opt for in the #3 Utorch being modded by Clemence. Im thinking I will not go with sw40, as originally intended, Im becoming more interested in cooler High CRI options. I may go with another sw45, am also considering a 5000k Optisolis, based on the very balanced and high levels of the saturated colors, R9, R10, R11, R12 and R13 on the 3000k optisolis posted above. That decision will depend on Clemence being willing, and arrival of an LED board for the Optisolis. I dont know if the Voltages of the Optisolis is a good match for the Utorch… the quad E21A did not work out because the voltage was too low, and the Utorch driver was increasing the current, and decreasing runtime, so we went to a single E21A.

For your Armytek I dont think there will be an issue with using a quad E21A, I suspect that is where your Clemence mod is headed, and I trust his judgement.

I have a couple other warm lights, 3000k N219c versions. Though I like them in full darkness, and on my nightstand, I dont think I need two more warm lights, Im finding I use the SW45 more often than my 3000k options. Im still really excited to get the E21A 2000k. It color is much more orange, in a way I like, than the 219c 3000k, that I find overly yellow (which I improve with a Lee 1/4 minus green filter).

fun times in the LED selection world, all thanks to Clemence

"And a couple Zebras.. you can see they are very low in R9, which imo is the reason there is so much “tint lottery”. Its not really lottery, its just that the High CRI Zebras have very low R9.. Not a lot of red, so the green and yellow dominate their tint."

I can't agree with you, because new mkIV Fc and Fd Zebralight's with XHP50.2 has much better color rendering,

that old models,

foe example H600Fc mkIV

I has H600Fc IV and Sc600Fc IV, both has good color rendering.

I say about significant difference between old Zebras (H600w, H600w II, H600Fc III) and new mk IV - new are much better.

Tint ?

Both Zebralight's has nice tint (very slight green in Sc600), these Cree XHP50.2 (imho) better, that Nichia 219b (9050 grade) in my 2 old flashlights, better , that Nichia 219c in my old flashlights.

(I can't compare with Nichia 219b (9080 grade), because I dont' have it.)

Compare with my Osram 's flashlights (CQAR.CC) 4000K : OSRAM's has slightly better color rendering and tint.
