The Nichia emitter gives a ring with the smooth reflector (note Sofirn comment about the SST). I get around this by using a diffuser from a laptop screen (or you could use DC Fix).

I’m not claiming that it is so in your particular case, but many times a ring from a smooth reflector is not caused by the led itself but by a slight defocus. Paying attention a proper focus, maybe sanding a bit off the bottom of the centering piece, maybe use a different piece with a different height, can maybe make the ring disappear?

Since using the White Flat, I have focused ( ) more and more on getting the focus of leds right in my builds, not just of speciality leds like the White Flat but all of them. Getting the focus of a led right in all 3 dimensions is a pain and an art, and the resulting beam is highly satisfying for a flashoholic.

Interested if they come in silver and LH351D, the others are too warm for me.

I found there are not many people vote on this thread, I think I have to say no.

I can upload all the mini versions of SC31B, SP32AV2, SP31V2, SP40 which are compatible with 18350 tube onto sofirnlight.com, no other changes of the models, just replace the tube and battery which is easy and keep cost down. But people always love to see more changes, it needs quantity to fulfill that changes and keep the cost down at the same time.

Sorry I have to say no. And I am learning to say no after reading the article “Why can’t Chinese just say NO?”

@Scientist

Is that a purple shorty tube from an S2+?

Yes. Unfortunately it did not fit as made. I had a friend with a lathe turn down the threads so it fit.

I am sure you are correct. I just put it back together and didn’t bother with adjusting. I may give it a try sometime. Thanks for the tip.

:+1: This is the best kind of “no” — “no” with (IMO valid) reasons. That way, maybe other approaches can be proposed, or at the very least there is good understanding.

Maybe just making a 18350 tube available for order is a good enough solution?

Also, I wonder if there is an equivalent “Why can’t Westerners just… ?” companion article. Would be interesting!
