If I ever could get the $$ for a spectrometer, I’d totally be posting nice spectral charts with CRI, TM-30, etc…
Anyone want to front me a few thousand? 
That’s a gorgeous LED. I would like to go put that in a very well diffused host for some work.
Check out the GB thread for these, the spectral results were posted earlier today.
I just noticed that both 219B and 219C exceed the rated lumen output
- 219C 9050 specced 240lm 700mA; Tex's test: ~255lm 700mA
- 219B 9080 specced 220lm
700mA; Tex's test: ~230lm700mA
It’s a good thing
Yes, I think the D240 rated emitters are actually D260, the spec sheet says they exist.
The D220 are technically within the margin of error for a D220 IIRC but also keep in mind my sphere is not perfect, just as good as I can get it.
Hmm, yes, don’t trust our BLF calibrations. The limited chance I had sofar to compare different people’s calibrations, while I expected maybe 4 or 5, it was more like 20 to 25. A humbling find!!
Those were mentioned before but it was guesstimated they would be hundreds of dollars at the cheapest.
Let me check it. If it’s not that expensive, I might buy it. So you guys can passaround it to calibrate each sphere
I have been drooling over those when they came out last year 
Calibrated components always costs at least an arm and a leg… 
Unfortunately they do not solve the spectral errors of our luxmeters 
, but they give a better absolute output reference than a couple of ANSI-rated flashlights.
Im planning buy some of this leds (when available) and build a single and a triple.
Anyone know whats the best way to proceded in DD with this led?
I know that the best is to stay around 3-3,75 Amps. Max 4. So… 10 to 12 amps in triple.
So, whats the best configuration for stay in this margen at 10-11-12 amps?
For wire i think that 22awg its the way (not 20awg)
For driver spring i think that steel (default convoy) without bypass.
For tailcap spring i think that steel (default convoy) without bypass.
And finally for the cell ncr18650ga? 30q will be too much? vtc6?
Any info?
Open to opinions 
I built a triple with these awhile back and just did it like any other triple. I think I used 22awg. I have no issues with it over driving the LED’s since the Vf on them is pretty high.
Hi, i have some question
you measured the AMPS at max?
You bypass or not bypass the springs?
Cell?
Thanks for your help!
Yeah, I forgot what the messured amps were but they were not anything to worry about, around 10 amps IIRC. I generally use GA’s in my personal lights but I generally test with 30Q. Either way it should not be an issue with a triple. Even if they are overdriven some it will not hurt then and it will quickly drop as the battery drains.
Where can these LEDs be purchased?
Last I knew they were out of production but maybe Clemence has managed to get more? I have not been keeping up with his stuff lately.
Maybe somewhat unrelated but some nice high-CRI Osram Oslon emitters can be bought at pargos-shop.
Hope I can try some in a near future. 
Cheers ^:)
Got a link to a specific item? I just seen 1400 listing of random electrical components.
First of all thanks for your help. You not mentioned but i supose that the 10 amps (aprox) is with bypasess springs right? I think i will go with 22awg and phosphor bronze springs for driver and for the tail. And lets see whats the measurements are. Probably stay in 8-9 amps and thats will be perfect because from 9 to 12 ( in this led) its not much gain in lumens but more heat.
What do you think?
