Comparing 20 LEDs (with and without high CRI) in 14 Convoy s2+: final personal observations

[Yokiamy]

You forgot the famous 219b

You forgot the famous 219b

I did not notice he missed that one! Have shells with early and late production of each bin I could get my hands on. Do not miss that one!

@ChibiM

And which manufacturer has 2 LEDs with the same CCT but 1 with high, and the other in low CRI?

Do any? Maybe between a version 1 and 2 emitter? Maybe in the Cree lineup with xp-l’s or xp-l hi’s? Now you are going to make me dig! Maybe Nichia with the early iterations of the 219b, I seem to remember 9080, 9050… were there others?

I remember when a cri of 70 would have been a godsend! I think that is why the xp-l hi’s at more or less 70 do feel pretty good after the days of the xp-g and xm-l.

Doesn’t Samsung manufacture LH351D in 70 cri also?

I think in only some CCT’s?

[Quadrupel]

Get some Cree from Mouser

[Haukkeli]

LH351D 4000K 70cri
LH351D 4000K 80cri
LH351D 4000K 90cri

[mattlward]

Well, there is the answer! LH351D come in CRI flavors!

@MaverickMCS

…something like the lh351d or XHP50.2 at 70 and 90 CRI and same CCT and do a comparison.

Those two and the XHP70.2 are the ones that first come to mind.

Ok, and now I want them soldered on boards :D who sells them.
I don't like modding, so having them on boards is kind of a requirement, and available at normal sellers (not Mouser)

Normal list…
Mountain Electronics (USA)
KaiDomain
Fasttech
Emisar/Noctigon thru Hank
Convoy (Simon) on AliExpress

[Quadrupel]

“Normal sellers” …from China… sounds like a joke. O.K. maybe Saimon and Hank only.

[ChibiM]

I made a list for 10 LEDs so far, but don't know where to get the LH351D in several CRI.

2 on the list are 4500K though

Haha lol. No, Mouser is a bad joke!

Who in their right mind would suggest them, lol. And they don't even have the LEDs I am looking for.

Cheapest shipping option 20 EURO.

that's a joke!

LH351D 90CRI Spectrum Tests

I have now purchased most variations of the 90CRI LEDs from Digi-Key. I also reached out to a few other vendors to try to get info on some 4000K 90CRI bins for sale in larger quantities but so far nothing has panned out with that. I created one thread already for the 2700K SPHWHTL3DA0GF4WPN6 part but I will also be doing some tests on the 3000K, 3500K, 4000K, 5000K. Any undesirable ones I will (probably) attempt to slice them to see how it changes the tint. I’m a bit sick of SST-20 for it’s va…

[ChibiM]

Thanks Yokiamy.

I just checked Digikey, and they have some in stock (that are sold separately) but also shipping is no fun..

Total cost of 2 LEDs incl shipping: € 26.93

Unfortunately, that's not worth it for me.

[Yokiamy]

Maybe contactr has some spare?

[ChibiM]

Oh, that way. Yeah, I will send him a message

[ChibiM]

Ok, I placed the following order:

14* Concoy S2+ (1* with Nichia 219C, and 13* with Luminus SST20 4000K) at Fasttech

20* clear lenses (because I read some people said the AR coated lenses from Convoy shift the tint/DUV)

And the following LEDs at Kaidomain

LED	CCT	CRI
CREE XP-E HEW Q5 5D2	4000K	80
Cree XP-G3 S5 5C1	4000-4500K	-
Cree XP-L HD V4 5A3	4000-4200K	-
Cree XP-L HI U6 5A3	4000-4200K	-
Cree XP-L2 HD V3 5A	4000K	-
Cree XT-E S4 5A3	4000K	-
Nichia 219BT	4500K	92
Nichia 219CT	4000K	80
Samsung LH351D	5000K	90
Samsung LH351D	4000K	90
Samsung LH351D	5700K	90

Wanted to order at intl-outdoor, but although Nichia 219B(T) LED was a few dollars, shipping was $8

Some aren't 4000K, but just wanted to try them.

I decided to order complete S2+ lights, because they already have everything installed, and I just need to replace the LED boards.. much quicker, less stress, and maybe even cheaper.

I'm not into modding, so if something fails along the way.. you may never read about this again :D

Cree XP-L HD V4 5A3 from kd are veeeryy rosy. I have them in Q8. Love the tint.
