Convoy S21D vs Sofirn IF25A TIR swap

Nice story of the “little house on the prairie.” :slight_smile: :+1:

A red/green house with white snow all around is so very Christmasy. I could easily imagine making a Christmas card with this shot :slight_smile: .

Haven’t measured it exactly, but 26 big steps. So let’s call it 25 m.

Feel free to use it to send to your fellow flashlight friends. Need a higher resolution? :beer:

I have to admit the thought has crossed my mind. But every year I’m too late sending cards… I’m terrible at that kind of stuff.

Thanks very much for the offer but I too hardly use Christmas card anymore. Cheers.

I had overlooked Simon’s listing with the quad optic… So I just ordered the optic + MCPCB. The latter might be useful for testing at some point. It will be interesting to see the IF25a with 60 degree optic as I normally use pocket lights only to light up things relatively close to me, for in the garden, or when hiking, etc. so a wide beam is better. At the same time I also ordered some wide angle optics to put in the FC11 and some SST20s of which I will use one to replace the LH351D that is not bad but esp. in situations with a lot of wood, colours just feel off.

Btw, as to Sweden becoming worse, if you would return to NL that may give a bad feeling too. As an example, when I see some TV programmes at a relative (I don’t watch TV), the people who are presenting and those who are participating in/invited to TV programs, and politicians, all seem to be only 2 generations away from idiocracy.

Having that separate MCPCB makes it so much easier to swap and try different things without having to reflow 4 emitters. One thing still on the todo list is that 2S2P mcpcb and use a 6V boost driver. Just for fun. Probably with some warmer 519As.

Oh coming back is not an option. Both societies are very similar, so that cancels out imho. Scandinavia has 1 huge advantage over NL: nature. Once you get used to the silence and darkness (read lack of light pollution), you’re hooked. Shining a beam up at the sky while the milky way fills your view. Although you get a little heart attack if you walk around the corner and all off a sudden you’re eye to eye with an elk. They’re big!
I do miss the architecture of old buildings though. Before coming here I lived in Haarlem for 5 years and always enjoyed the city centre. Very much worth a visit. And get some freshly roasted nuts during the Saturday market. Or warm stroopwafels :wink:

Simon now offers 60° bead, 30° bead, 10° bead, and 10° flat….

…but I am looking for 30° - 60° flat style. Anyone know where they can be found?

I always got mine on Amazon, things like a 10pak of each size I wanted.

Eg: https://www.amazon.com/s?k=collimator+lens+led+20mm

Go crazy…

(Nb: these are for 20mm lenses, adjust for other sizes.)

These quad pods aren’t common Carclos, in which case I could get a 10624 or whatever. Thats why I’m trying to find out exactly what will fit.

Anyone demonstrate a perceptible difference between 60° flat vs beaded?

Beaded, from what I’ve seen, is just the difference between OP/SMO on a reflector, ie, it just smooths out artifacts.

Wider-angle TIRs generally don’t need that, as they naturally “blur” nicely.

I’m trying to reproduce the beam on my Wuben TO50R which is wide (~45°) but has a hard cutoff at the edge. Beads and / or frosting scatter light enough to attract bugs from the side.
