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

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

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

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!

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.

Maybe contactr has some spare?

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

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.

We'll see! :D

I mean.. I hope to see it.. they are not here yet

What are you going to do with them all after testing?

I’ve heard a rumor that very soon there will be a huge S2+ giveaway around here… :smiling_imp: :innocent:

Cool that you’re doing this ChibiM!

I wish you could also include a 4000K 219B, E17A/E21A, and Optisolis to your list. The 4500K 219B that you’re getting from KD is the non-sw45k (i.e. non-rosy) version. It’s the sw45 which is brighter and still nice, but quite different than the sw45k. The 4000K 219Bs that I got from Ilumn are one of my favorite LEDs.

Too bad we’re not in the same neighborhood so I could contribute to your list of 4000K LEDs.

Gt-fc40 4000k can be had in m21c for 35 usd.

B35am 4500k in s21a for less than that.

I’ve done similar tests to what it looks like you are planning. I used Solar Force P60 hosts. This makes it easy to swap pills for comparisons.

That Cree XP-L HI U6 5A3 LED is one of my favorites in lights I can live w/o high CRI.

I’ve sampled the LH351D LEDs from several on line sources. It is my favorite LED for good compromise of CRI, tint, and lumens.
But they are not all equal. The duv difference is significant from source to source.
Every 351 I’ve tested look better to me shaved to ~1mm. It drops the CCT, and more importantly, duv.

Of the different CCTs, the lowest duv samples I’ve found are:
5700k: Version from KaiDomain is OK. I’ve tested samples from KD and Convoy. Not many places to get a 5700k, 90 CRI LED.
5000k: I’ve tested versions from DigiKey, KD, Convoy, and Sofirn. The best version is R6 flux bin from DK. It is close to the first samples I bought in a group buy from AEDe.
4000k: I’ve tested versions from DigiKey, KD, and Mtn Electronics. None quite match the early group buy from AEDe, but the Q6 flux bin from DK is close.

I also like the 3500k Q2 flux bin from DigiKey.

I know shipping from DK can be high but there can be a big variation in Duv.

Happy Testing!

Hi Chibi, I will get you 3 leds that you are not allowed to miss in your comparison: 219B V1, in R9080 4500K and in R9080 4000K. And a SST20 in 4000K. I assume on 16mm DTP boards?

Hey Djozz, that would be really cool.

I'm also talking to Hank about the 219b, on a board. I'll probably have to order the DM11 to get free shipping on the LED ;)

((And review the DM11 that is)

Simon now has 4500K Nichia 519A R9080 for sale. But you already made your order.
