WTS/GB: NICHIA 219B NVSL219BT-V1 R9080 EMITTERS! sw45k, sw40, sw35, sw30

The 219c 4000k looks rosier than the sw40 and sw45 in that comparison. That sw45 is not a sw45k correct?

Also is that 219c 4000k the stock emitters that comes with the FW3A? Surprised how nice it looks considering all the the 4000K 219c I’ve seen in the past are greenish.

Yep that’s the 219c in my FW3A. I was also surprised at the quality of these 219c since most of my other 219c are usually more on the yellow/greenish side. Also you are correct, the sw45 isn’t the k variant but it does have some rosiness to it. This was just a quick photo from my DSLR at a custom white balance of 5000k. Results from the camera are never as accurate as how people see these emitters with their own eyes.

Wow I wish Lumintop would be willing to sell some emitters to us individually like Convoy does.

Yeah, it’s really hard to find a good bin of the 219c. Besides these on my fw3a, the only other light I have really nice 219c are from my Oveready BOSS.

Hi Azhu, just curious here when did you get this Oveready BOSS? Or when was the approximation date it’s made

Thanks,
Clemence

It was the very first run of the Raw Ti finish. Ordered back in Jan 2018.

Ah, I see. Thanks

Did you sell these? I think I recall Dan mentioning that he got them from you?
If so and you still have some, I’d be interested in a few :wink:

Yes he did. :wink:
Only few left, all the codes are the same but I have no spectrometer to validate if they’re the same tint.

sw40 on the Lumintop Tool25

Are those the sm4070e?

No, this is the Nichia NVSL219BT-V1 sw40 D220 L2 R9080

Sorry, meant to address Clemence on the topic of 219c. The ‘e’ is a special bin similar to ‘k’. Be nice if they were offered for sale by whomever :wink:

Ah, I believe those are the sm403.

afaik

sm403 is N219c 4000k 3 step MacAdams elipse (relatively close to the BBL and usually above the BBL)

sm407e is a very pink 219c, guaranteed to be below the BBL
(I hope someone posts the chart, I cant find it atm)

sw45 is an N219b 4500k, that is not usually as pink as the sw45k
here is an excellent post with more pictures

sw45k is an 219b 4500k, and is supposed to always be significantly below the BBL

the sw45k and sm407e are similar in that they are both below the BBL, and have magenta (pink), tint

-

btw, A lot of people mis use the word Tint when they mean Color Temperature

they will say, I like Neutral Tint, I dont like Cool White
this is wrong language!

They mean, I like Neutral White CCT, I dont like Cool White

Neutral Tint is not the same as Neutral Color Temperature
Neutral Tint is tint that is not green and not magenta, it means Tint that lands on the BBL

See here from Clemence’s site:

That bin allows for fairly large negative duv values. I assume Nichia prefers to keep most of the small duv emitters in the sm403 bin for customers who require uniformity, so that should leave sm4070e with lots of rosy emitters.

I didn’t realize before, but Clemence apparently had (now out of stock) those in D240 output and L2 voltage, which are also good bins for each of those specs.

Andy, group buy for these too? :smiley:

Very helpful!
Andy was correct when he said 403 (is the yellow wedge actually 4030e?),
along w 4050e and 4070e, they are all below bbl

+1

I received my emitters today, I changed the stock xpl of a nitecore tup to a sw45k. I definitely like it, I don’t see any red but slight hint of pink and color rendition is great. Output has been reduced to about half , didn’t realize that was going to happen, The nitecore tup is rated at 1,000 lumens stock and with the sw45k it’s around 500 or so.
