I’ve never tried lee filters on the 219B, only the SST-20 and he made it better.
Here’s a comparison between a shaved sw30 vs a normal one.
Shaved 219b 9080s are in my experience the most beautiful emitters ever. Not very bright, but the absolute best choice for small cell EDCs IMO (especially with boost drivers.) The closest thing to zero angular tint shift and reliably rosy™
Can I have 10 sw30 emitters?
You got it. PM inbound
As a general rule, lower flux bins are more likely to have lower Duv, simply by nature of the greener tint being more efficient (and hence higher luminous flux). This is one of the reasons 219C has a reputation for somewhat mediocre tint after 219B, because Clemence was ordering the highest flux bins available for all the group buys, and most sellers have done the same afaik. It’s not a hard and fast rule since there are rosy D200s and neutral D180s, so it really comes down to the individual reel because the ANSI binning for 219B in R9080 isn’t exactly all that precise.
UPDATE: I have a few sw35 available again
I’ll take 10x sw30 and 10x sw35 please.
Thanks!

You got it. PM sent.
Can you send it to Japan?
I’d like
10× SW45
3× SW35
please.
Yep that’s not a problem. PM inbound.
Are the sw40 D220 still available? And is the current batch neutral or slightly rosie?
Yes it’s still available. Tint will vary depending on the light its installed in but generally it’s on the neutral side.
May I order 2 of each please?
Sure thing. PM inbound
