Someone has messed up those graphs above: in the 5000K graph it seems to me that R9050 and R9080 is reversed, in the second graph the red line is missing.
Clemence wrote; Correct! Mixing several different CCTs will also (in most cases) results in lower CRI than individual CCT. You can check Maukka’s test to see it. It’s more like a trick.
Nothing changed, everything is as shot except exposure adjustments (those were two different flashlights with slightly different brightnesses). 219C has greener tint while E21A is right on the target (check Maukka’s chart below)
WB adjusted to get rid of tint differences. This 219C has R9 = 76, one of the best 219C in my collection. But E21A still wins.
Sad but understandable.
Personally I think the same….but just initially.
That’s because there are no stars for it and it is not well known.
But for most applications that I can think of this LED should be technically better than XHP70.2 (I don’t know the price, so it may not be so good commercially). I hope it catches up….
It could fit the Virence VR16S1 Star with scratching.
And as driver it would work with 4S Buck-Driver like it is in the GT.
Haikelite MT07S could be a good host for it.
Being higher voltage than the XHP70.2 used, the MT07S would probably drive the 149 pretty hard. Given the mode spacing of that light, I suspect it would work well.
I’d buy one, but probably only one. That doesn’t make it worth stocking.
And so it did a few days ago, thanks Clemence for checking the whereabouts of the package for me!
Here is the first of the E21A sm205 R9050 leds in a Lumintop Tool. The tint and colour reproduction is not far from the 2000K Stanley led that I tested before, of course the Nichia has just that bit more red in it
I found a single 3000k to be fantastic in a zoomie. In an ultrafirr uf10 to be more specific. It is about 2amp direct drive off a fresh imr 16350, just about its max spec

For your information:
The nearest reliable post office located 23km from the workshop, thus I normally only ship twice a week (monday & thursday).
