LED centers itself. But when I tap the LED to get rid of excess tin then it shifts to the side. When I try to move it to the center it runs to the other edge.
I suspect that the reason is a smaller anode and cathode pad on Nichia LEDs. I don’t have such a problem with other LEDs.
Hmm that’s strange. I’ve never had this issue with centering. I normally use the blunt end of a toothpick and gently tap the center of the dome to remove excess solder.
Not a huge difference but the correct diagram for my emitters is below:
Azhu, I received the package a with sw35s. As always, everything fine. Thank you. A lot 
UPDATE: Stock levels for sw35 and sw45k are starting to run low. Don’t know when or if I can restock these again once they’re out so if you need some, hit me up before it’s gone.
TTT
I will take at least 12 sw35 emitters. PM’d about quantity discount.
Update: I’ll take 30 sw35.
UPDATE: sw35 is now SOLD OUT. Contacted my vendor but no ETA on next restock yet.
Interested in three 219B SW45k.
edit: would also be interested in sw35 if/when you get them back in stock.
PM inbound
Interested in 10 of the 219b sw45k!
Has anyone modded a MF01 Mini with SW40’s?
Does it have a violet spill?
Is the loss in range and lumens big?
The sw40 I offer doesn’t have a violet tint. If you’re seeing violet, it’s most likely due to the coating on the glass lens.
Personally I don’t think the lower output is significant. Most of the time, I use my lights for close to medium range work and don’t require a huge wall of light or throw so lumens is less important and CRI is more desirable for me. Depending on your usage, that might vary.
How come in the OP, you have SW40 DUV at –0.0031 and 0.0007?
They were two different tests. –0.0031 was done by another member and 0.0007 was done by me.
I wonder why the huge difference.
I will take 25 of the sw30.
Possibly a different setup. Bare emitter readings can be different from reading it through an optic or reflector.
I assume you tested with optic/reflector since bare emitter is always rosier.
Yeah. Tool AA with some dcfix. I wouldn’t say it’s super scientific. Just a general idea of the CCT and where it is broadly on the BBL.
