WTS/GB: NICHIA 219B NVSL219BT-V1 R9080 EMITTERS! sw45k, sw40, sw35, sw30

Received too, Thank you for the kind words ! Will definitely order more soon

My sst20 4000k were not that bad.

No. I didn’t used the hotair. In a separate thread I wrote that it stopped working in the middle of soldering. The heater burned down. I had to use an electric stove and a solid aluminum heat sink so as not to put the mcpcb directly on the heating element.

In addition, I had to reflow several times, because 219b always move to the side. It is a miracle that leds survived it.

I don’t know if this is normal. I always have a problem with these leds.

What do you mean when the LEDs move to the side? Are you saying yours don’t center itself correctly when the solder melts?

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 :smiley:

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.
