Also new on KD:

http://kaidomain.com/Flashlight-DIY-and-Tools/LED-Emitters-or-LED-Star-on-PCB/Samsung-LH351D-Neutral-White-5000K-High-CRI90-LED-Emitter

Also in 5700K 90CRI and 3500K 80CRI


Wow. That 3500K is a dream come true. Great CCT. I like CRI 80. It’s even 1 bin group above what datasheet offers at this CRI/CCT.

Also new and interesting: 3 new LH351D leds, 3500K 80CRI, 5000K 90CRI, 5700K 90CRI. But there is no mention of the exact tint bins or product codes. Ban: can you provide the exact tint bins of these LG351D leds? Or the product codes? That is quite essential to many of us CRI-lovers.

I looked closer at that. There are many contradictions and unknowns in the listing:
  • picture and title say CRI80, description says CRI90
  • title says T6 F4. T6 colour bin is 4000k not 3000k. But T6 is also a flux bin group – and higher than what Samsung lists.

So…BanL, it would be very useful if you clarified what bin is that.

OKay

I will re-organize the product title.

Thank you

I see that there was an update – the Samsung product code is SPHWHTL3DA0EF4U0T6.
This means:

  • 3500K
  • 80CRI
  • T6 flux bin group
    • one higher than Samsung lists for this tint/CRI
    • this is not an exact bin, this group consists of T2, U2 and V2 bins which go from 400 to 460 lm
  • ANSI binning” – this basically means that tint can be in any of 16 bins. May be very rosy but may be very green
  • F4 voltage – again this just means “any voltage”.

Note that this is a code used for ordering rather than exact binning.
The reel should have the exact bins for voltage, output and tint specified.

So – thank you BanL for this information. It is really useful. But if you managed to get the exact binning from the reel it would be even better. Smile

ADDED:
The 5000K CRI90 variant is SPHWHTL3DA0GF4RTS6:

  • 5000K
  • 90CRI
  • S6 flux bin group
    • the highest for this CRI/CCT that Samsung lists
    • this is not an exact bin, this group consists of S2, T2 and U2 bins which go from 380 to 440 lm
  • ANSI binning” – this basically means that tint can be in any of 4 bins. May be very rosy but may be very green
  • F4 voltage – again this just means “any voltage”.

I think adding a photo of the reel label will be the best solution.

Hey, i just received an order here, and this includes a quad SST-20 with optics.

I’m pleasantly surprised to see that it fits just fine, as long as you stick the feet of the optic in the slightly narrower slots.

The slightly wider slots are for the screws.

…but the narrower slots are still too wide… Sad

You’ll have to secure the feet in the slots with a drop of Kafuter UV curing glue (or something similar, as long as it hardens / doesn’t stay flexible) before screwing on the bezel / screwing in the pill (depending on the light).

It’s very subtle but check and make sure the optic is not resting on the LED substrate. It’s hard to see any problem but once you crank down a bezel it could cause issues at that point.

Dang, it seems i spoke too soon, again (bad habit…)

You’re right, the optics do rest on the emitters AND the slots are still too wide…

Only 1 of the legs does not sink too far in the slot…

Thanks for the warning. Thumbs Up
