Thanks maukka. Exciting LED. Good job Lumileds.
Thanks for great test as usual!
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.
Have the 90cri versions been available ever?
Led4power probably meant the MZ and Z ES which he sent me as well. I don’t think there’s a CRI90 Luxeon V.
Not yet.
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
It’s a little bit more efficient.
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)
wow, that’s awesome! Especially the higher output part.
So swapping one of these with an XP-L2 in the same light will result in higher brightness, longer run time, better tint and less tint shift?
So we get these from Led4power?
OK saw your edit, Led4power has it on the 16mm board so it should fit SP32A
EDIT I might need to enlarge the reflector opening for this?
although it’s only .5mm difference.
You just need to ream the hole in the centering thingy a bit, I use a hand reamer for that.
I just stuck a knife into the centering ring and whirled it around, no big deal.
No, until 17mm boost driver are available.
96lm/w 5A
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.
Thanks, I’ve got some hand reamers (and just about every tool under the sun ) so no problem, also had thoughts of TIR optic for that light
Thanks kiriba I do recall T/A’s test.
This is an exciting emitter, even though only 70 CRI
Also now looking at L4P’s LD-B4HV for a 2S project. (not this led)
Curious now how this compares to the Samsung LH351D 4000K 90cri ?
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?
im not sure why Djozz is rating the 351D with such low output. If you look at Texas_Ace tests it pulls way higher. If you subtract like 22-25% from his numbers to account for 4000K and 90CRI you will probably be close to your estimated output.
I would guess ~1200-1250lm Samsung and ~1650lm Luxeon V? Both will look way better than the XPL2 with SMO reflector. Not much tint shift in corona. They wont be “rosy” like a Nichia 90CRI but shouldn’t be green either (this is personal preference, I guess some people like that pink color)
I have this emitter in the D4 and convoy s2+ triple. Super floody…and super bright of course.
