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.
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?
Great
Have you tried measure spectrum at very low current like 1~3mA?
My sample at these current look much more greenish and bluish compared to 0.1A you measured,I guess Duv and blue light increase much more.
Does that will happen less with lower power Leds like E21A or the ones used for strip lights?
The current stock of SPHWHTL3DA0GF4RTS6 (dog farts) at Arrow is the worst batch of LH351D I’ve ever come across. Duv ~0.0065 at both low and high current, and CRI doesn’t even reach the rated 90. At 3A they’re something like CRI 87.5 with an R9 of 40. Even slicing them down to the phosphor still gives a significant positive Duv and sub-90 CRI. Utterly atrocious
