On average we expect an SW45k to be more rosy than an SW45 [/QUOTE]
I think that is an error
I believe this is more accurate
both the sw40 and sw45k have great red rendering, the 45 CCT is cooler white, and its tint is pinker
Can someone tell me how to differentiate the cathode and anode sections? I also having trouble finding a data sheet anyone have a link. Thanks so much.
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.
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.
