Although I like how it turned out in the Tool mod (indeed about 50 lumen on high) the best way it can be used in a flashlight is the same way as the Optisolis: multi-led and lots of diffusing.
How do you get to the LED in a Tool? I tried it in the EDC01 which looks like it’s set up the same and ripped out the driver 
PM me if you don’t want to take this thread off topic.
On topic though… i would use this LED just for the lack of cyan dip (though ideally i’d like a little more violet, but that’s just me being fussy). I rarely use more than 50 lumens, and it might work better behind the pebbled TIR in the EDC01 
The Tool Ti is a bit different, it has a brass pill that does not screw into the head, but on one side the battery tube is screwed on the pill, and on the other side the bezel is screwed on. Easy to mod (if your led refows centered that is 
).
The beam will certainly be cleaner from a pebbled TIR optic.
Thanks for the test Djozz, I saw this LED earlier. The symmetrical dual dies beam looks a tad better than Optisolis indeed. I can’t see it from your pictures but I bet there must be cheerful rainbow party in the beam. Any TIR optic with heavy micro lensed surface will cure the beam easily, just don’t expect clean narrow beam.
If only the voltage is at least the same as Optisolis, which already too high for most EDC lights, this could be a better alternative than Optisolis. Output wise, it’s very good compared to warm Optisolis.
These Sunlike and Optisolis are (still) the misfits in our flashlighting world. Their native territory are those in general lighting as groups or clusters behind diffused optics.

No they are not suitable for flashlights, just the extreme good CRI makes it tempting to try to fit them anyway. But I like the Tool Ti as it is now with peach-coloured corona. I may make a 4000 lumen quad flashlight out of these as well, with OP reflector and heavily frosted lens.
Waiting for a 219-Optisolis…
Thanks for the info Djozz, my copper Tool looks to be the same as my EDC01, i’d rather they were like your Ti Tool!
I really like the look of these LEDs, appreciate the review. Do you think having the LED extend into the reflector rather than sit behind it would make much difference?
It has a rather defined hotspot actually so the focus seems about right.
If you do this mod you must realise that the led-minus pad is soldered onto the thermal pad of the XP-board and you have to make electrical contact between thermal pad and the led-minus of the ledboard. I did that in a rather clumsy way that I do not recommend (a little wire that of course got in the way of the center piece.)
I see that Soul now offers a more powerful SunLike variant, STW9C2SB-S.
It’s rated to 200mA/6V max. Has thermal resistance of 10 K/W which is among the best that I’ve seen so far among MP LEDs.
Too bad that it’s 6V but overall it may be good…
Hm. Looks like yolk in the pot
:person_facepalming: I had to click it, and you’re not wrong…
I looked at the color spectrum in the datasheet. I still see a peak at 450nm (blue wavelength). I thought these use violet pump instead of the typical blue. But still the amount of blue light emitted is incredibly low for the CCT. Great for use before sleep.
The pump is nearly violet though, looks like about 420 nm, just like the cool Optisolis CCT’s. The peak at 450nm I would expect to be the first fluorescence peak.
Hello everyone.
If anyone knows where to buy STW9C2SB-S CCT6500 please let know.
I ordered some short Sunlike strips from LEDrise.eu. Not sure if they have what you are looking for though.
Those are 0,2W led but i am looking for 1w. Searched the whole net but cpuld not find:(
Must be somewhere in Asia market for sure.
If you read the graph in the OP, you see that the led works perfectly fine at 400mA/3.6V, which is 1.44 W.
Thanks for the test!
The Seoul P4 high-cri (the first commonly availbale high Power high-cri LED) also had an orange corona back in the day.
First of all I do not like to exceed recommended ma.How long will leds last at 400ma,more than twice that recommended. 3000 hours,5000? I think not more than that. Unacceptable period for me.
Better to get 1w and use them at 250ma they will last at least 40.000 hours maybe even more.
Midpower leds are usually mounted on FRP boards, my test on an MCPCB may not be completely representative for normal use of the led. Further, flashoholics (the main target for my tests) are not usually concerned about what happens after 1000 hours. ,So on top of my test results, what current will be ideal is largely dependent on what you will build.
I’m still using my HDS with stock Seoul SSC P4 for its very good CRI despite its poor lumens to size ratio.
I mentioned its peculiar beam pattern here. Once I got it, it stopped my flashlights quest for many years.
I’m a bit puzzled by McGizmo’s measurements about the CRI R12 = 66.1 because to my eyes it has deep and dense blue colors rendition, better than most CRI90 LEDs. Blue colors look better than with a SST20 4000K to me.
