I swapped the led in a Sofirn SP33 for the 4000K 90+CRI Samsung LH351D, and I’m in love with this led. Texas Ace already showed with a 5000K low CRI version that this led has great output and can handle a lot of current, I can confirm what maukka found: this 4000K 90 CRI version has a very good tint (and colour rendering of course), and it behaves absolutely fine in a smooth reflector.
So I swapped the led, I bypassed some springs and fiddled with the current sense resistors, and now my SP33 puts out 950 lumen OTF at 3.8A current, which is quite an achievement with light of this quality.
I’m almost convinced to swap these leds into my Q8.
I’ll take 10.
A very nice offer, thank you.
And thanks for all of you who went through testing these LEDs.
@AEDe, as I’m a paypal-noob you need to tell me the exact sum I have to transfer. I have no idea how much paypal fees add to which kind of transaction.
Here is some random leds from my discard box. You can find nice size comparisons in CRX's Leds 'n Stuff thread too, but this gave me something fun to do :-) . The real die sizes will be viewed enlarged for the leds with dome, but that is how the optic will see the led as well so what you see is the relevant size, well, sort of
