Interesting stuff jon_slider. Thanks for sharing.
Do you know what the white-balance setting was on the camera during these pics?
no
I use iPhone w auto white balance
to help it use an approximation of daylight white, I include a cool white light in the group lineups, and I take the photos sitting near a north window during daylight hours
except in the photo showing the incandescent light ON at night, which biased the white balance towards 3000k incan, thereby showing the sw45k as “relatively” blue
my pics generally include a selection of LEDs so that people can see “relative colors”, and if they own one of the LEDs in the photo, they can gain a “relative” idea of the “color” of other LEDs they may not own. (Tint is not the same as CCT, tint and CCT are separate factors contributing to our perception of color)
my perception of LED color changes dramatically between those times when my brain white balance is adapted to daylight, and those times when my brain is adapted to my incandescent house lights
therefore the CCT I prefer during daylight is not the same as the CCT I prefer at night. however, in All cases, I prefer Tint below the BBL.
Ok, thanks.
Jon, I actually didn’t know there is a N219b 4500k 9080 SW45 and a N219b 4500k 9080 SW45K. What is the difference? What does the “K” stand for? I couldn’t find any info in the spec sheet.
If my understanding is correct, the sw45k is under the BBL (more rosy) than the sw45. The sw45 could be under the BBL as well but the sw45k is guaranteed to be under so you know for sure that bin is usually rosy. I’ve had a batch of sw45 that was slightly rosy but overall, it’s more neutral white than the sw45k.
Hello I will take four sw45k d200 L2 r9080 and two sw40 d220 L2 r9080

Oh that’s very interesting. Is the suffix “K” added by BLF folks to indicate below BBL color bins because I can’t find that in Nichia specs?
I would like 20 of the N219b 4500k 9080 sw45k. Thanks!
Hello, I’d be interested in 10 sw45k, 10 sw40 and also 10 of each, sw30 and sw27, in case the group buy comes through! 
It’d be nice if sw45 & sw35 were available too.
Check with Andy. He had these tints before and he might have some if its not sold out.

I’ll probably be in the doghouse once they arrive, but I’d like 10 of the 4500k sw45k d200 L2 r9080.

In
sw45k d200 L2 r9080 - 20
sw27 219b r9080 - 5
I would like 20-4500k sw45k d200 L2 r9080
The Suffix is actually used by Nichia. You can find it on the data sheet. Not sure if they discontinued the sw45 prior to this though.

I would like
- (5) 4000k sw40 d220 L2 r9080
- (5) 4500k sw45k d200 L2 r9080
