I made a quad with this and love it. To me it makes the Nichia 219C 4K look way too rosy by comparison. You wouldn’t think it seeing the Nichia by itself but once you have them side by side it feels like that, color rendition aside.
Honestly I'm now even more impressed with this led because tint looks great for low CRI led,with negative R9. I can't wait to see how 90CRI versions of this LED would perform.
thanks for the great info and graphics maukka
too bad there is no 90+ CRI
the present samples have negative R9, not a good thing in my snobby world
I do like minus green filters, they have helped me a lot
I use a 1/2 minus green on my Olight S1 Mini High CRI and it makes the green tint much less noticeable, but it would be nice to buy an LED that did not need a filter, especially on lights like the S1 Mini that cant be opened to put the filter under the bezel.
good thing Im so picky, it makes me accumulate lights more slowly
I was getting ready to order a 4000K XP-L2 for a Sofirn SP32A when I came across this, I see this is only a test for tint/CRI but I’d like to know how would this compare to the XP-L2 as far as output?
I tried to find info in the spec sheet but couldn’t, I’m used to the Cree datasheets, guess I just need the simple answer
Simple answer: compared to the XP-L2, the Luxeon V has better output, lower voltage, better tint and no ugly yellow corona around the hotspot.
Less simple: the 4040 footprint does not really match the 3535 XP-footprint, but with a precise reflow it will work (or else get the led on a dedicated ledboard from led4power)
112lm/w 5A
But in direct drive with same config that powered xp-l2 with 5Amps you will get something like 7.5Amps with 86lm/w.
For linear drivers like LD-*4 you can just compare lm/Amp. 1653lm XP-L2 vs 1820lm Luxeon V, both @5A.
At 7A the Luxeon V puts out 2200 lumen, the Samsung 90 CRI led probably just 1400 lumen. But that is not the whole story, the Luxeon V runs at a lower voltage so the efficiency difference is even larger and in direct drive the Luxeon V will draw more current, with again more output.
That said, for a led with such good tint and CRI, this Samsung has very good performance.
For the light I’m deciding between these to use in (Sofirn SP32A / un-modded) it’s not DD and is pulling around 4.7A max at the tail, at that current what would you estimate the outputs / difference and which one would you recommend for it?
