Since Sofirn sourced 2700K were nice I bough some more to put in some light bulbs, I also took one 5000K and 4000K to see how they test :
4000K :
0.1A Ambient = 1829.6 Lux, CCT = 3905K (Duv 0.0044)
Color Rendering Index (Ra) = 92.9 [ R9 = 72.9 ]
IES TM-30-15 Rf = 91.51 Rg = 99.27
0.5A Ambient = 7292.8 Lux, CCT = 3928K (Duv 0.0037)
Color Rendering Index (Ra) = 92.4 [ R9 = 71.5 ]
IES TM-30-15 Rf = 91.43 Rg = 99.85
1A Ambient = 13191.3 Lux, CCT = 3943K (Duv 0.0030)
Color Rendering Index (Ra) = 92.1 [ R9 = 70.7 ]
IES TM-30-15 Rf = 91.18 Rg = 100.29
2A Ambient = 22691.5 Lux, CCT = 3956K (Duv 0.0013)
Color Rendering Index (Ra) = 92.2 [ R9 = 70.1 ]
IES TM-30-15 Rf = 90.81 Rg = 100.58
5000K :
0.1 Ambient = 2210.7 Lux, CCT = 4730K (Duv 0.0030)
Color Rendering Index (Ra) = 92.7 [ R9 = 58.1 ]
IES TM-30-15 Rf = 89.52 Rg = 97.55
0.5 Ambient = 8847.3 Lux, CCT = 4817K (Duv 0.0038)
Color Rendering Index (Ra) = 91.8 [ R9 = 54.3 ]
IES TM-30-15 Rf = 89.75 Rg = 97.91
1 Ambient = 16101.2 Lux, CCT = 4870K (Duv 0.0039)
Color Rendering Index (Ra) = 91.3 [ R9 = 51.7 ]
IES TM-30-15 Rf = 89.70 Rg = 98.05
2 Ambient = 28038.4 Lux, CCT = 4949K (Duv 0.0037)
Color Rendering Index (Ra) = 90.7 [ R9 = 48.7 ]
IES TM-30-15 Rf = 89.47 Rg = 98.33

I emailed Digikey the other day to ask about some color bins, I didn’t ask for a lot because I doubted they would reply, I got the reply today :
SPHWHTL3DA0GF4WPN6 (2700K) : 798 pcs F2 W7 N2
SPHWHTL3DA0GF4UPP6 (3500K) : 759 pcs F2 U7 Q2
SPHWHTL3DA0GF4TPQ6 (4000K) : 481 pcs F2 T6 Q2
Not sure how this info is valuable though because we don’t know if the bin you tested last year were the same.
thefreeman, work your magic and see if Arrow will reveal what their 4 in stock 90 CRI bins are: arrow results
I’ve never seen anyone able to get this info so you must have the magic touch.
Do you see a sales email on their website ? They have a contact form but I can’t find an email, I’d like to join a picture of the label, that’s what I did last time so that the sales rep sees what I’m talking about (i.e. the ”magic” ), can’t do that with the form.
Edit : Nevermind, I found it.

assuming you found websales@ good luck!
That’s the one, we’ll see if I get a reply.
Speaking of Arrow I see that they now offer free shipping to EU for orders above $50 like Mouser and Digikey (actually less since it’s 50€ for those two), a few years ago they offered free shipping with no minimum which was insane, they stopped because that was probably not sustainable, then there was no free shipping at all so I dismissed this vendor. But it’s good that it is again an option, and they do DDP incoterm like Mouser so no custom fees.
As checked with the warehouse team, the available bin codes for below part numbers are as follows:
SPHWHTL3DA0GF4TMQ6 - F2TMQ2 and F2TMR2
SPHWHTL3DA0GF4RTS6 - F2R4T2, F2R3S2 and F2R3T2
SPHWHTL3DA0GF4VMP6 - F2VMP2
SPHWHTL3DA0GF4UMP6 - D2UMQ2, F2UMQ2
That’s what I feared with the large quantity available, they have multiple bins and I doubt they’ll let you choose from one reel with an order of a few pieces.
Edit : There is actually no detail on the chromacity bins except for 5000K (R3, R4, which are bad)
Re edit : ah no, ”M” means 3-step MacAdam, so 3000, 3500 and 4000 are all 3-step.

A few interesting pieces of info here but ultimately not what I hoped.
1) there is a different, lower, voltage bin (D2) in that one LED.
2) various brightness bins in the same CCT
3) “TM” “VM” “UM” not helpful in determining where LED might end up on BBL unless I misunderstand their specs.
So, what is the preferred source / part number for these in ~5000k these days?
I’m definitely not as familiar with the various color/tint codes as others in this thread but maybe these are a good choice for me to purchase a small pile of?
Order today, ships today. SPHWHTL3DA0GF4TPQ6 – LED Lighting LH351D White, Neutral 4000K 3V 1.05A 128° 1414 (3535 Metric) from Samsung Semiconductor, Inc.. Pricing and Availability on millions of electronic components from Digi-Key Electronics.
your link is for 4000k
here is 5000k
if you want to make the tint less green, you can slice the dome off, which also makes the LED about 500k warmer.

Anyone know what bin Wurkkos has? It’s quite good for 5000K.

Anyone measured spectrum of 3500k from Convoy?
I PM`D Simon at Convoy, and this is the current LH351D 5000k bin SPHWHTL3DA0GF4RTR6 F2R1T2. Does anyone know what the bbl or duv is of this bin?

In the datasheet page 10 , R1 should be similar to R2 but slightly higher CCT.
Edit : it’s one subrank flux bin higher (T2 vs S2), that can mean a worse tint sometimes (green being more efficient).
I got some but I still haven’t tested them
Dang I bought 4 of them, before I asked Simon for current bin.
Do you happen to know Simon’s current bin for lh351d 4000k?

Thank you,stock seem not so good.
Do you like tint when sliced?

I prefer the one from contactcr that is always below the BBL, but it looks okay.

Does dedome lh351d decrease even more the CCT and also blue peak than slicing?
Would be interest on stock 2700k
