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.
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.
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.
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.
