Thanks for the testing djozz!

Can you possibly add to your review that these 4000K are binned D200.
I believe your early 4500K(5000K) were binned D220 and your 219C binned D280.

Here is Nichia binning chart

Well… Not the results I was hoping for.

By your wording, have you heard that Nichia is indeed doing a 90+ cri 219c? Last I heard that was scrubbed

Thanks THE_dAY for the bin table, I added the bins to the OP.

@pilotdog68: I have no news about a 90CRI 219C, I just hope they will dio them sometime.

Thanks a lot for this test, Djozz.

The highest spec’ed R9050 B-V1 is D240, so that one should sit in between the B-V1 and C you’ve tested, output-wise. But then, first you’d have to find some…

EDIT: Guys, those Jaxman lights at fasttech and their aliexpress store appear to be NVSx219B-V1 R9050 sw40/sw57. D220 for the sw57.

Thanks djozz.

I did not know that Fasttech carried the Jaxman lights now (was my suggestion in their thread), that is good news! I will order an E2 :-)

Nice review.
Thanks.

This LED is definitely my favourite tint even if it’s not as efficient as a 219C.

I think I can confirm that the emitters in those Jaxman lights are NVSx219B-V1, indeed. They sent me a few LEDs. I thought I’d have to mount and test them for low Vf to confirm it, but a nice and clever member of TLF found a way to tell apart bare 219B’s and 219B-V1’s (thanks again Megalodon). Should I spoil it or give you guys some time to find out for yourselves?

13

Spoil it, spoil it!

14

I feel challenged here, but I'm not at home to check them, aaarrrgghh! .

15

There are small differences in the footprints.

16

Interesting. I guess that’s a good way to tell a 219B from a V1

17

Exactly, PD. Should also work when emitters are mounted already.

18

Chouster, thanks for sharing the helpful tip!

19

Of course, with pleasure if someone finds it useful.

20

I’m pretty sure I’ve got a bunch of nichia B around for some time. I’m going to dig them up and have a look.

21

Is there anyone who could build a copper p60 drop in with a 219b v1 93 cri 4000k ?.
Thanks.
For a solarforce l2d.

22

I may be missing something here, but what is the difference between the B V1 and 219C, other than the colored pads?

Thank you for all your time testing LEDs djozz!
