I bought a couple of those, they are very cuddly warm white with rosy tint. Most leds in this tint region are above 80CRI, but if it is 90+ I could not say.
If Fasttech is correct (I don’t trust any spec from any product from Fasttech) in that this is the nvsl219at-h1, than this must be the sw27 colour rank, so 2700K.
But frankly, it looks even warmer than that!
I made a S2+ triple today with these leds to see how the tint is in a TIR optic. and it is again different but closer to the reflector optic tint; the close to rosy tint with little yellow from the i3 aspheric lens zoomie was not achieved. Not a bad tint though.
Against my principles here’s a white wall shot that compares some lights (I do not show whitewall tint comparisons usually because they do not represent the reality very well, and people still will use the picture to discuss tint).
left the XP-G3 4000K 90CRI in a S8 (reflector light)
middle top the XP-G3 4000K 90CRI in a S2+ triple (TIR optic)
right the XP-G3 4000K 90CRI in a ‘on the road’ i3 (aspheric lens zoomie)
middle bottom Nichia 219A 4500K 92CRI in a solarstorm SC02 quad (TIR optic)
The Nichia shows brown-ish on pictures which is not true, the blue-ish hotspot of the S8 does not show well. But you can see how the i3 light is close to the 219A while the other two builds have a tint more to the yellow side.
What the sheesh? Now this may sound like a cheap joke but, does cutter gets the majority of high-CRI Cree leds, which may explain why it is so complicated to find them elsewhere?
Moreover, I've not taken an in depth look there but this can be read there:
“14mm Round DTP TPAD MCPCB with the U2 bin XML-2, 7D2, S6 min 90CRI”, which is bogus. That “the U2 bin” should be edited and replaced with an “an”, doesn't it?
These look very promising. I’m ready for a 2700 lumen High-CRI triple!
I’m disappointed about the tint, but I haven’t had the chance to try all mine yet, hopefully there’s a winner in there somewhere.
They’re an authorized Cree distributor and sell a TON of LED’s, so no conspiracy, I’d guess buying power.
The owner is a member here at BLF as well as most other hobbyist sites like MTBR, CPF, etc., been supportive of our “hobby” for more than a decade.
I’m sure that’s a typo on the XM-L2, it’s in one spot on the page header, not the description. Never saw anyone complain about getting stiffed by exaggerated claims.
Most likely. It’s far too large an improvement over the high CRI competition and cree’s own PDF only has 90 CRI LEDs up to R3 bin. The 4000K S3 are all 70 CRI. See page 7 in here .
Nice to see that Mouser has the 4000K 90CRI too. Still not good for Europe, Mouser’s shipping rates are almost as high as Cutter’s, when ordered from here.
No actually. Cutter has real CREE LED's that do not show on CREE datasheets. Cutter gets some exclusive small batches (relatively small) of rare bin/tint LED's that CREE can't list or sell normally because the yield is too small. That's small for the big buyers (say 10K plus), not small for us.
Perfect example is the XPL W2 bin LED's - yes they are real and not listed in the CREE XPL datasheets.
I'm on the side of think'n these are legit and Mark got his hands on rare yields that CREE can't sell to their regular large customers. With small yields of exceptional LED's, CREE can't group them in lower bins because they would be out of spec, and can't list them because they can't make them on demand in high volumes to fill orders.
