Use the lens to replace the relfector of Convoy S2+ flashlight

Do you have a link? I’m looking on LED-DNA and I only see 15, 45 & 60* ones.

10 Degree Optic

The optic is identical to the one sold on Aliexpress:
10 Degree Optic, Lot of 10

Ah thank you, didn’t realize they had their own site, I was on their eBay site.

Thank you for the comparison!

On topic enough, I hope, but I recently got some TIR’s, and they didn’t lens the spill (the light from front of LED), so they still have the cold coloured spill and the warm reflected area…
Now how silly is that? :^\
And who knows what you get, as many sellers use the same pictures…
Anyway, I thought it was something to mention for when you are out there on the quest for the perfect TIR deal.

CNQG has TIR optics

So does Fasttech

Been using a 10* TIR in my D4 tube light for around a year and love the smooth beam. Current incarnation is TIR from fastech, dedomed xml2 T6-4D and 3 x 7135 driver. And its actually too bright as a EDC the hotspot hurts my eyes at less than 10’!

What I don’t like about reflectors is the tunnel light effect, with TIR you can see things in peripheral vision much better.
Plus once it gets dirty/scratched just pop a new one in, reflectors always seem to get dirty even tho try hard to seal the dust out. I don’t have a lens in mine and it takes a couple of months to get to the point it needs changing. That’s with heavy everyday use. Much cheaper than buying a lens+reflector every couple of months.

Good mod :slight_smile:

You can get the Carclo line of optics @ LEDSupply for very reasonably prices (<$1.50) apiece and free shipping in the US. I imagine the quality is superior. I just picked up a little variety to see how well they perform!

I have a Carclo 10003, but was disappointed with the result. I tried it with and without the holder, and couldn’t get as nice of a beam as I could with the one I got from LED-DNA. The beam ended up taking on the square shape of the emitter most of the time. I’ve heard that they work pretty well if you can get the focus right by using the right combination of spacers. It certainly wasn’t a simple drop-in upgrade for my S2+. I didn’t try any of the other Carclo optics, as the 10003 had the tightest beam of any of the Carclo optics I found easily obtainable.

Huh. Well, I’ll see what I can do and post up the results! I ordered the 10003, –15, –25, and the -L25.

Sweet!

For S2+ and stripe lens - the lens was loose (tested in two different S2+; doing exactly the same as on video in this thread). Used additional o-ring on the front (https://www.fasttech.com/p/1088604; so two in total since there is one already there) and now stripe lens isn’t loose.

Using additional o-ring also makes these optics fit S3.

Not sure which exact ones he uses but based on the order form it looks like Richard at Mountain Electronics uses some of these lenses designed for the S2 lights for his 3 LED Triple XP-G2 high output “S3” light. I will know more when the one I have on order arrives. Richard lists the lens option I ordered as the 10511 and describes it as the one most closely resembling a standard reflector beam.

Why do you find the square pattern a problem? I happen to thing it is really good. and from my understanding that is about as tight as you can get.

I am wanting to get a Convoy Sx X being 2 2+ 3 4 5 6 or 7

I am going to convert one of the above to a 219B light. I think I would like to add a 10 degree to this light, but the LED’s are a different size. Would I be locked into using a Carclo in this combination?

Thanks Matt

My Convoy s2+ came in today. Managed to install the TIR lens from LEDDNA. It fits nicely, did not have to trim the white holder. Merely pushed the thing in with a little force.

I just installed a 10 degree TIR from LEDDNA in my S2+.

The original OP reflector was not great for throw. With an XPL HI V2 3D emitter at around 5A, the throw was 13,500cd with original OP reflector. With the TIR properly adjusted so the emitter image filled the reflector, the throw increased to 21,500cd at around 5A.

I’m very happy with the improvement. It seemed to reduce spill, and also reduced the corona around the hotspot some. So the hotspot is a bit more well defined, but there is still a nice gradient from the hotspot to the spill. The TIR throws about as well as the smooth S2 reflector. With the same emitter with the smooth S2 reflector, the throw was 23,000cd.

It took a little fiddling to get the TIR installed correctly. The white holder it came in was too large to fit in the S2+ head. Also, the bottom of the white holder is flat, so the solder joints on the MCPCB prevent the TIR from sitting correctly. So I had to remove the white holder. The correct focus was achieved when the bottom of the TIR was about even with the surface of the XPL HI, so an appropriate spacer is needed. I cut out the part of the white plastic holder that fit around the emitter and used this as a spacer. The TIR without the white holder almost fit nicely in the bezel of the S2+ head, but with the oring in place the TIR would not sit quite completely level, so I kept the glass lens in place to keep everything level and maintain water resistance.

I can concur that the white plastic holder does not go into the S2+ easily. At first, I did not think it would fit at all.

I installed the 60deg optic on two of my S2+. This is the 60deg lens that Simon has for sale here).

My first attempt to install the 60deg was to remove the clear optic from the white plastic housing and then place the optic on top of the original orange peel reflector. This actually worked. However, once I read this thread, I decided to try and install the entire piece (with plastic housing). On the first S2+, I was able to "screw" down (with needle nose) the white plastic housing (not easy), until it was all the way down. On the second S2+, I was able to push it all the way down (took some force).

first attempt - optic on top of original orange peel reflector (actually worked). I now realize that's not how it was supposed to work.

Second attempt, I was able to install the white plastic housing as well. Fortunately, you get five pieces, so there's room for trial & error).

This gives a nice creamy smooth floody beam pattern, just what I was looking for.

Oh, and unfortunately, that video that Simon posted never seems to load - so couldn't watch it.

Thanks for posting and reviving this old thread…read it years ago and forgot about it, I recently ordered the 60 degree TIR’s for an S2+ shorty I’m building (also to try in my Nitecore HC30)

It was interesting to read the feedback here again on the 10 degree spot optic, I have 5 of those plus a 15 and 30 degree I bought back in 2016 (after reading this thread) but I never tried them because I ended up fitting a long SMO S2 reflector into my S2+. That reflector seemed to improve the throw nicely so I left it alone, but I just dug up those TIR’s to give them a try now too.

Here’s a link for the reflector I mentioned:
