Convoy S21D vs Sofirn IF25A TIR swap

Triggered by our resident grizzly, but may be of interest to others as well. A quick TIR swap comparison between the Convoy S21D and Sofirn IF25A. And yes, the Convoy and Sofirn TIRs are interchangeable without issue.

Camera set to manual, everything same settings and WB.

S21D stock 60 degree TIR

Really great comparison photos. I’m guessing you’re a little north of Texas?

Middle of Sweden. It’s been absolutely insane today, never seen anything like this this time of year. It’s supposed to be spring by now. Just 1 night of snow. Car got stuck 3 times this morning and I had to dig the wheels free with a frigging ice scraper while the wind was blowing snow horizontally Facepalm Gave up since the underside of the car was completely stuck as well. Fortunately a kind family along the road let us stay inside while waiting for the snowplow the clear the road. All ended well, but this was definitely the strangest weather so far this year. Was strangely enjoyable though, something different Smile

Great info, the 60 degree flood optic with no other options was hoding me back from trying this light, but i really want to.

 

I have read here before that IF25a otpics can be sourced on Alix, but I don't know where i saw that..

 

Does anyone here happen to know the brand / seller of those IF25a replacement optics? Thinking it could be nice to try multiples in the new Convoy quad!

This topic was a bit confusing at first as I only found S12Ds listed with trip LED reflectors, but then I looked through the convoy store and saw the S21D with 4 LEDs and a TIR, so it seems you mean the S21D?

From the beamshots I’d be interested to try out the wide 60 degree optic in the IF25A, is there any place you can buy that optic loose? I didn’t see it in the Convoy store…

What the… you’re absolutely right. I don’t know how I’ve been able to write S12D instead of S21D…. every single time! Title and post corrected. Thanks for pointing that out.

As for the optic, I only know of Simon selling it as combo package (mcpcb + optic). But you can probably get it separately. Either from him or some other store. Can’t imagine it’s a custom designed Convoy only optic.

Very nice and nicely controlled photography. Thank you! I’m glad I saw this thread.

I would like my S21D to be brighter so this clear Sofirn optic should do the trick. The spill/spread suffers a little bit with the more throwy clear optic but worth the trade-off. I ordered a couple for my 2 S21D’s https://www.sofirnlight.com/products/quad-optic-lens-for-if25a (thanks for the link).

BTW, I started shivering just looking at your pictures Innocent .

Thanks! I designed and build it myself about 5 years ago. Long story short; 7 years ago I bought my house because it was cheap and crappy. But I saw potential and I was so naive to think renovating would be easy peasy. Oh boy, how wrong I was. Once I started opening up walls/floors, I discovered it was in much worse condition than I initially thought and the power tools started piling up. And I needed a work place that was not the living room. Let’s just say that causes significant stress in a relationship. So something had to change and I decided to build a separate place for storing everything and have a place to work while leaving stuff without anyone tripping over it. Sanding, painting, that kind of stuff. Construction plans, electric wiring and looking up regulations during winter, then build the following spring and summer. Highly recommended if you have the space, it’s very satisfying once it’s done. Just wish I made it a few m2 bigger, seems I always run out of space.

It’s fully isolated and has electricity, but needs some finishing touches. It’s good enough for now. Future additions would be water and maybe a small fireplace/cooking stove so guests can stay there. I’m actually Dutch, but emigrated to Sweden about 10 years ago. Textbook cheesy love story (didn’t last though). Moving to Sweden seemed like a good idea at the time, but the country has changed a lot the past years (not in good way) and I wouldn’t have moved here nowadays. Anyway, getting sidetracked. So all my family and some friends are in a different country. The little house allows them to come by and visit for a few weeks when they want. Works wonders when parents come over, but they are not in your face the whole time. They have their own little house to sleep and wake up in and then spend daytime together.

Hope you liked the story behind the cute house Wink

“…and the power tools started piling up.”

That got a belly chuckle out of me. Smile

I’ve admired that little house, too, from your previous photos, and wondered what it was. Looks too nice to be just a storage shed or a shop, but small for a home. Perfect. Good colors, too, nice choices.

Yeh, and I always wanted a little hideaway. Guess it’s the kid in me who still wants a treehouse or other “den” that’s just small and comfy.

Same here! Did you notice the ladder on the left? That’s going to be a simple treehouse for me my son. Or at least a platform. The tree had to go, but who says you need to cut it at ground level Wink I saved the original floor planks (28mm thick spruce) that I ripped out of the living room and was thinking of using them to build something at some point. So why not use part of it as a treehouse floor.

This thread is getting so derailed Big Smile

Out of curiosity. Which LED is in your S21D? Is it the 519a?

There’s no replacement for displacement.

I can tell you I’m happy with it. I’ve kept the 60 degree optic in, since I don’t have so many wide angle lights. It’s a very nice evenly lit view you get. And the tint is quite unique with it’s magenta. It’s especially obvious when use with white snow as you can see in the pictures. As for the host itself, it doesn’t win a beauty price. It’s functional, but I’m not a shelf light kind of person. Flashlights need to be used, either practical or for fun!

Excellent comparison shots.

It looks like the clear optic gives a bit less flood/more throw.

How far from the camera is the cute little house? 10 meters?

Nice story of the “little house on the prairie.” Smile Thumbs Up

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