Have never measured the same light with both LEDs, sorry.
It’s pretty overrated IMHO. Like most other 70CRI emitters at 4000K and below it just looks like it’s putting a yellow color cast over everything.
Now that Hank has a much better bin of SST-20 there’s zero chance I would pay more money for worse color rendition.
I am a hi cri guy, so almost always go for the hi cri option. But I do still appreciate the 5D and 7A xpl hi.
It just always had a decent tint, good efficiency and does not run hot. You are just sacrifice a bit of cri.
lovely!
Where can I find more information about current SST-20 bin Hank has?
He mentioned he has SST-20 4000K FA3 and FD2. See this thread.
the 5000k XPL HD, and does not have anywhere near the throw of the XP-L Hi,
and both are still Low CRI.
beyond lumens, compare the candela
XP-L HI 4000k : 45,000cd
XP-L HD 5000k : 27,000cd
SST-20 4000K 95CRI: 41,000cd
The SST-20 4000k has higher Candela (52% more throw because of a more focused smaller hotspot) than the 5000k XP-L HD
…
Low CRI LEDs always look green to me :confounded:
NW XP-L HD compared to NW 219b
NW 219b compared to NW XM-L2
the High CRI SST-20 4000k option in Emisar D4SV2, has only 10% less Candela (throw), than the Low CRI XP-L HI.
Even though the SST has 30% less lumens, it has 400% more Red CRI R9, in addition to the 36% higher CRI Ra.
CRI R9 is the Red Bar:
I encourage you to experience High Quality light spectrum that includes Red spectrum, beyond Quantity of lumens that have an excess of Green spectrum.
High CRI LEDs these days are not the lowgrade stuff our parents used to smoke.
Join the High CRI Revolution! :+1:
5D should be very rosy. If you get it and it’s still too green, you can always sandwich a lee 804 between the lens and optic.
Thanks for all your input. My only high CRI light is the Sofirn SP36 with LH351D 5000K emitters and that one is a disappointment. While the CRI is definitely there, overall tint is pretty green.
true!
duv is what we call Tint… the sun has green tint of duv 0.0032… the LH351d is farther away from the BBL, and is indeed greener
focus on the number in the green oval (smaller number, closer to 0, is better):
5000k LH351d:
by comparison, the SST-20 is less green, it has a lower duv than the LH351d
and the SST-20 also has more Red output, and a tighter throwier hotspot than the 351d:
SST-20 4000k 95 CRI:
maybe give High CRI another chance, with a smaller, less green tinted LED 
This is interesting, thanks for the graphs. Is there any real disadvantage with SST20 4000K 95CRI? Why are they so frequently referred to as poor man’s XPL HIs?
My opinion is CRI isn’t everything. CRI-Babies are like audiophiles and spit at the mention of anything under the metrics but I think a pleasant tint for everyday use is just fine for most us. I get we are in a flashlight forum but, ultimately, it is whatever works best for you.
I have over 100 lights…from very crude utilitarian ones to large custom ones and maybe 60% are high CRI including a few custom 219B sw45k’s and E21s in Zebras. The truth of the matter is I use my stock zebra sc64w Hi and LT1 the most of the time. My PL47 and Wurkkos FC11 gets a lot of usage around the house as well. You can graph peep all day and talk about the BBL being the “One Line to Rule Them All” but I find it amusing to be honest. High CRI is great but I wouldn’t let it be your only decision maker.
Also, my D4V2 XPL HI 4000K is great…don’t listen to the haters. The SST20 is a great every light emitter but just isn’t that special to me. The XPL is more efficient, throws farther, stays cooler, and is brighter than the SST20 to boot.
less lumens, more CRI
here is an xp-l hi
I call that R9 Red CRI bar pathetic, it looks like a limp lingam :smiling_imp:
(pic is a link to original info from maukka)
it is true the sst has greener tint than the xp-l hi, but not greener than sunlight.
Both are greener than the incandescent BBL.
it is 2020, friends dont let friends settle for Low CRI :disappointed:
time to look beyond lumens and tint
it is time to also consider Candela, and Color
4000K 5D is a great outdoor LED, its efficient, bright and looks nice. I have SST and Nichia 4000k lights, and while the CRI is impressive, they lack the ‘punch’ outdoors that makes me leave them inside or use when I’m feeling artistic instead of ready to blast stuff! 
Nah, I have plenty of 5D lights and none of them are yellow. Not sure what batch of 5D Hank got this time around (maybe 5D1 or 5D4?) but the ones in my KR4 Ti look straight up PINK. It’s like a 219B without the high CRI. It’s almost too pink during the day but at nighttime I actually prefer it over my SST-20 and LH351D 4000k lights. it’s one of the few low CRI emitters I enjoy using because the tint is so good.
That’s it! My three 5D lights (KR1, RRT01, Jetbeam-II MK) all win the beauty contest against the SST-20, allthough it’s a nice LED. Have my SST-20/4000K from kaidomain (target: Fitorch P25). Lovely light, but in direct comparison the Cree looks much more rosy.
But yes, a colorful scene is best enjoyed with a HCRI LED. It’s just that this is not the only use case.
Dunno the light, but behind a TIR lens it should look quite nice. A and D are below the BBL (ie, rosier) while B and C would be above (ie, greener).
While I didn’t like the stock 4C that’s the come-with LED with a bunch of older S2+es, way way way too fried-eggy, behind a TIR lens where the colors are all nicely mixed, even the 4C is quite nice. And quite natural, more like sunlight. I often describe is as nice warm sunlight.
So if you like rosier, the 5D should be warmer and still rosier. Can’t say how it’d look in a reflector light (likely a bit of a fried-egg beam: warmer yellower hotspot and cooler bluer spill), but behind a TIR it should be awesome.
Awesome!
These XPL-Hi do run a little warmer in the color temperature range compared to others at 5000k. I have several 5000k lights and this one is way warmer. I’d almost call it a 4500k light. The XPL-Hi I have in my S2 and EDC 18 all are this way. Not sure if their 4000k is the same. But I find the 5000k very pleasant. One if my favorite. Not sure what tint it is though.
I never understood high CRI. I don’t care what the true color of something is at night, its light time. 4500K and lower reminds me of flashlights of yesteryear, dull and annoying. But to each is there own and you know what they say about opinions.
