Uh, my link says otherwise for some reason :exclamation:
DB it doesn’t list the led as 5000k 90 CRI but when you look at the part number and match to the datasheet, that’s what it is.
+1
This is why I posted the specific list of the links. So, members could order the right LEDs :+1: 
If you click the product page, you can switch to ‘Digi-Reel’ packaging and buy ’em one-at-a-time, but they ain’t $1 each. 
This is the US site.
I just changed the .ca to .com
I studied the Samsung spec sheet, learned the reasons for all the lettering and text in their label, and that’s what I go by. The Digi-Key in the US doesn’t sell the 90 CRI 5000K in singles. The 80 CRI ones I bought were $2.64 each as compared to $3.57 or so Canadian on the links posted above for the 90 CRI version. The Canadian site also has W6 power bins available that the US store doesn’t have at all. Now if we could only find the 96 power bins…
Ah, the devil is in the details.
I won’t buy an S6 power bin when W6 is the current highest available. 4 levels down in power, no thank you.
Edit: And following that last provide link shows a W6 in the US store, Digi-Key is SO confusing… I’ve spent hours in their store in the past few days and bookmarked the highest bins, searched it out all over again a few minutes ago and U6 was it, now that link shows differently, how I don’t know but there must be some discrepencies in their warehouses or something and it’s frustrating. lol
I’m trying to figure this out. For me it works DB. Clink my link above “US site” and try to order.
Okay, there it is. Not the same bin. But they do sell LH351D 5000k 90CRI’s 
Yeah, I don’t mind getting decent CRI if I can get power, if I have to sacrifice too much in the power department I’ll go with an XP-L2 or SST-40 or whatever. No point in wasting time to build an underpowered light. 
JK, to some degree… some lights demand something special and there are allowances that can be made. lol
Edit: FTR, I searched it out new a little while ago and specified Samsung, LH351D, and 90CRI… the only thing they stocked showed 800 counts. Odd, their site is apparently unreliable. Crazy…
From Digi-Key’s US site:
From Samsung’s datasheet:
It seems their ‘minimum order’ quantity won’t prevent you from adding a single emitter to the cart.
So, yeah, that’s the highest possible bin for a 90CRI+ 5000k LH351D.
No such thing when I ordered the other day, I paid $21.21 for 6 of the 5000K 80 CRI emitters, shipped was $3.75 USPS and $1.62 tax. 3 days to my door.
I build for power first and foremost, if it can’t make the numbers I don’t buy it. Unless of course the light demands something special and high color rendering index is the flavor of the day, there have been exceptions but very rarely do I undercut the power first requirement. I’ve even ordered emitters from Cutter in Australia to get what was otherwise unavailable to me, yes, at $25 shipping. In a case like that I’d buy other things too in order to warrant the costs of shipping Internationally.
This was my first experience with Samsung emitters. They do well in my D4 as a Quad, not so much singly in other lights. Ok, and with nice color, but not overwhelming. I’ll use more, sure, but it’s not an easy go-to choice.
I ran a google search comparison changing the last two out put bin letters. No hits at all on anything higher than the S6 at digikey in 5000k 90CRI.
So at the moment that’s the top bin for high CRI in 5000k. 80 CRI 5000K is U6. 70CRI 5000K W6 as DB said.
In digikey I just use the search using the bin code and it gives me all the different buying options.
If they have a minimum listed and you enter “1” you’ll be paying $1500 for your “single” emitter. Ya gotta watch Digi-Key! Learned that a long time ago.
They typically sell by Reel, Digi-Tape, and Cut Tape. Reel is like 1500 5,000 emitters, Digi-Tape is 3,000 or 2,500 or 800 and Cut tape is 1 or more with price breaks at 10 and 50 and 100 as I recall. I’ve bought emitters from them in most of those quantities, only 200 at one time though.
Hmm…
I wasn’t brave enough to click ‘checkout.’
Still good to have for self entertainment though
Hi , thank you for answering even if partially . So generally the external part of the light is pretty durable other than lens ?
I have two D4s, a D1, and a D1S. My friend also has a D4.
I do not abuse them but I’ve been very happy with all of them. I use the D4s most, and have had a few drops onto hard surfaces without any failures. Just some scratches and scrapes.
The anodizing wears quite easily on my smooth black D4, but this is just cosmetic. It has a few bare spots from rubbing against my jeans while clipped to my pocket.
A broken lens is simple to replace by unscrewing the front bezel. If you break the glass lens, perhaps you could replace it with a more durable polycarbonate lens.
Im not looking to torture test them . for me if it can survive accidental drops on the ground and concrete and puddles of water is plenty good . where do i get the replacement lens from if say i broke it(i hope not)
