Anyone have any lumen numbers on these? Wondering how they will do in a Q8. If available I am thinking about buying some to offer as mods for Q8 owners.
I take it that 4500k 90CRI is not as option?
fully modded w/ stock LEDs:
XP-L V6 3D
0s: 6,369lm | 30s: 5,774lm
fully modded w/ LH351D 4000K 90CRI:
LH351D 4000K 90CRI
0s: 5,095lm | 30s: 4,687lm
These numbers were adjusted to be in line with Djozz-lumens
What do you mean fully modded?
With a spring bypass and everything?
@Texas Ace, no sorry. There is not a 4500k option that you have to order less than 800pcs, but there is a 5000k option.
In fact, I have gathered a list of all the LH351D 90CRI that I have found that you can order in single quantities.
Here is 5000k 90+CRI:

Here is 4000k 90+CRI:

Here is 3500k 90+CRI:

2700k 90+CRI:

Spring bypass and screws replaced using 30Q button tops
That is expected from 90CRI+ LEDs.
Pushing 1000 lumens+ out of these LEDs is amazing though. They are still 30% better than equivalent Nichia 219C LEDs.
Just replying to TA. I like this LED in all floody lights tbh
interested in 10x 3000K 90CRI LH351b
Thanks for the info, impressive numbers for a 90cri LED.
I am sure there have been beamshots posted but does anyone know where they are in this thread?
Links don’t work sadly.
Hmm, I just might get a combo of 4000k and 5000k and make my own 4500k setup!
Is this Group buy still open? Or do we have to buy then from digikey now? I didn’t see a recent update in the op and have not had time to read BLF outside of my own threads this whole year.
How much floodier are they then the XP-L? IIRC the die size was about the same?
What as the results of slicing / dedoming?
It is a bit floodier than the XPL.
Dedoming(slicing) actually works quite well.
Yes It is open. There was a delay at the supplier. But I finally got them today.
The Q8 reflectors still give you a nice hotspot though even with dome on so you will still get some of that signature Q8 combination love.
Any idea where this reel falls on this chart or do we need to test again?
Edit: I guess T6 after looking at the packaging closer F2T6Q2
yes everything are the same except about 125K colder.
Works for me, puts it closer to my personal ideal 4500k color temp 
I will take 20 (possibly more depending on exactly when payment is due) 4000k and 20 3000k.
Then if I can find that 5000k part number I can get some of those and try a mixed tint setup. That sounds very enticing.
@Texas Ace, you said my links were dead, right?
Strange. They were not dead 2 weeks ago.
Now I have to go back on the datasheet and search manually.
Ok, here are some not dead links:
Here is 5000k 90+CRI:
Here is 4000k 90+CRI:
Here is 3500k 90+CRI:
2700k 90+CRI:
Hope I helped you Texas Ace.
Ok, I ’ll write you down in the list. You can pay any time while LED are in stock. Now only about 400/800 of 351D are reserved.
Dear AEDe,
I‘m just checking how much LEDs I need. I get back to you soon. Do you also sell the LH351D 5000K with CRI 90 or CRI 70 only?
