Many thanks for the detailed answer, MascaratumB! :sunglasses:

If it was not for the throw you should keep the pebbled TIR. I know that clear optics can cause a green beam, I have the same problem in a FF E07 with Luxeon V2 and a D4S with XPL2.

Thanks Skylight!
Well, I can add something more than: the TIR is actually what turns the beam into a square. I experimented it on my RovyVon Aurora A23 (that also uses a TIR) and the soft beam of Luxeon V2 4000K undet a frosted TIR immediately turned into a yellowish squarish thing, nasty as f**k :confounded: It was even worse than this one

So, the issue is the lens! After I take the outdoor beamshots, I will blacken the white gasket to see if it avoids some of those artifacts (at least the greenish part) but I wouldn’t count much on it. A pebbled or frosted TIR will be a better solution.

@Skylight

Or they prefer the led because they got a cheap lot of it?

Maybe, or maybe due to efficiency. I still think that the led could be better (warmer in this case) but for a CW led, it seems better than a XP-L2 or XP-G3, that are hideous even the best TIR

@Skylight

Nice comparison beamshots! Sometimes it happens to me that once I take a whitewall beamshot of two or three flashlights I see which leds are more green and which are rosy. If you want a led to look green just put a 219B SW45K led next to it.

When I edit my photos I frequently notice that the camera sets a parameter not only for the color temperature but also for the green and pink colors.

I am having something like that, I guess. Sometimes, between beamshots, I have to close the app and then restart it (with the same settings) because it seems to assume a standard colour for all the beams. It is annoying :weary:

I am still experimenting the best combinations for beamshots, but they almost never represent what I really see! The more illustrative situation is with the Nichia NVSW219BT ~5000K that is “pure white” to my eyes, not rosy and that appears as rosy in the photos.

Oh well, we do what we can with what we have

@Scallywag

Wow, thanks for the detailed testing!

Thanks Scallywag, I hope it is helpful in some way

I was happy to see that after charging almost half the cellphone I was still able to use the flashlight for a while (if done on ECO I guess it would run for hours!) and the light hanged very well!
