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

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.

Glad you like it! The high r9 is supposed to help with red rendition. You don’t see red in the tint. It should be a little rosy like you said. With the Nichia 219b, you give up lumens for high CRI. Nowadays, I much prefer a beautiful color rendition over a lumen monster. I guess it varies with everyone but for 99.9% of my uses, I usually only need up to 500 lumens. Share some beam shots of the TUP with the new emitter. I’m curious to see the output with that particular reflector.

Let me see if this is possible :slight_smile:

For some reason during the past year everyone gives 219C such a bad rap. Here’s one of my first ever builds:

Purchased from MTN Jan 2018:

219C D240 4000K 90+ CRI

Turbo to Low on a FET+1 10507 uncoated lens

CCT = 4057K (Duv –0.0007)
CCT = 4069K (Duv 0.0011)
CCT = 4006K (Duv –0.0004)
CCT = 3988K (Duv –0.0011)
CCT = 3995K (Duv –0.0011)

I can’t explain the weird Duv spike in the middle. Maybe driver related?

That’s pretty solid! I’ve had mixed feelings on most of the 219c I’ve received so maybe it’s just a wide variation in production bins?

Hey azhu, posting pictures on this forum has always been a pain for me. If you want send me a message with your email and I will send them to you and you can post them.

This brings up another point. Why dont the big 3 parts companies sell any Nichia? Does Cree forbid it or something?


Thanks azhu for posting the pictures. The tir optic has a lot of artifacts and really doesn’t do this sw45k justice. I tried to get best picture I could but in real life it’s amazing, the more I use it the more I like it… Iam going to put another sw45k in a Jetbeam jet-st titanium can’t wait!

Looks like MTN got a very good batch of 219C. I wonder if the ones in the FW3A is from the same batch. So far noone tested the 219C on the FW3A. I’m going to order one from Illumn when they get the new colors in and test.

In for 10X sw27!

Andy can you please edit my request for sw27 to 10 instead of 5?
Thx

Done. Thanks for helping us get that much closer to possibly making this happen :slight_smile:

Over half way there for sw27 group buy. Spread the word! :smiley:
