He's gonna arrange the LH351Ds 5s5p and the LH351Bs 5s10p for even current distribution among the emitters when everything in series LoL. Total Vf to be expected for 30A driving current above 36V and power above the friggin' Kilowatt for a boatload of high-CRI light… }) :-D

Nah, just joking. :-D

Cheers :-)

I’m in for 8 of 351D 4000K 90cri when they come in. I suppose you’ll PM the paypal address?

319

Mmmkay AEDe, add another bunch of 10x LH351Bs in my name.

Cheers :-)

Can’t say I’m ready for a “one light to rule them all” build. Maybe someday (but NOT Sunday)! :laughing: Thanks for the laugh Barkuti! I can assume that 2 Q8’s, 3 BFL A6’s, a Sofirm C8F triple (and additional C8F host in the mail) will end up looking much better with the LH351Ds as they all are built for XPL’s. Even if I decide on something else for the C8F, I may just end up replacing the 5000k emiters that will probably end up going into the BFL lantern project with 4000k (I should have probably voted in that poll). I have no idea what I’m going to do with 50 LH351Bs. :person_facepalming: Love, Peace & Chicken Grease!

321

I love my LH351D…
Put me down for 10 please

322

Add me for another 6 of LH351D 90cri please :slight_smile:

323

Done

324

If it’s not too late to be added to the list, I’d like 9x of the 351D 4000K 90cri. Thank you!

325

i want 10 lh351D 90+ CRI, thank you

326

I would like 3 LH351D 4000K 90cri please.

327

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?

328

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

329

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:
https://www.digikey.ca/product-detail/en/samsung-semiconductor-inc/SPHWH…

Here is 3500k 90+CRI:

2700k 90+CRI:

Spring bypass and screws replaced using 30Q button tops

331

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.

332

Just replying to TA. I like this LED in all floody lights tbh

333

interested in 10x 3000K 90CRI LH351b

334

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?

335

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.

336

How much floodier are they then the XP-L? IIRC the die size was about the same?

What as the results of slicing / dedoming?
