About those tints, maukka gave me a nice updated tint chart. It explains a lot about why the A and D tints look so much better than B and C, among other things.
I definitely prefer the 3D and 5A tints of the BLF-A6, to Convoy’s offerings. It’s great that Convoy offers many choices (and I really like the 7A in some of their models, which nobody else offers), but I wish they’d stick to the A and D tints in all models. Even in the “3” tint offering, the 3D is so much nicer than the 3A (which tends to look almost cool white).
Respectfully but totally disagree. It may look fried-egg weird in the S2+, but in the S2 the 4C tint is by far the prettiest non-warm tint I’ve ever seen (slightly peach-y off-white, can easily pass off as pure white if it’s the only light source around, without the slightest hint of chromatic distortion), and that’s just one example. On my OP C8, it’s a little bit more yellow, but again, no hints of tint shift whatsoever: the whole beam is neutral, close-to-but-not-quite warm white. And while that’s all for my personal experience, I’m sure the other C and D tints have circumstances where they’re quite nice.
For the S2+, you might not be wrong, but judging the merit of a tint depends totally on the lens and reflector assembly of the torch the LED of that tint is set in. It’s impossible to make a blanket statement like that.
Yes, there’s certainly a wide variation in the tint bin themselves. It’s always a bit of a lottery. And AR coatings can definitely mess with how the beam profile shows tint shifts.
I really like Nichia 219 LEDs for general purpose lights. I’ve only ever had one “bad” Nichia 219 (it was yellow/green). Unfortunately, they’re not very good for high-output lights, at least not if you want efficiency. A 4000K - 4500K Cree LED is usually a good choice. Something in the 4A through 5A range is ideal (magenta side of the line, not the green side).
4C is okay though, i quite like it especially for ceiling bounce light up the room with warm cozy tint.
Not the S2+ Tan in 18350 version, but I guess it wont differ much from the regular S2+ on shorty version ! Both have batteries inside: the Tan version has Samsung INR18650-30Q flat top, the black S2+ has a Keepower IMR18350 750mAh, unprotected.
I took the clips out, just kept the magnets on the tail!
Thanks. Yes, I did some calculations after I asked my question, based on the indicated weight of a shorty tube and 18350 battery and got similar results… about 40g in weigh saving, give or take.
Yup, more or less like that!
But I guess the gain in size is the major benefit from these short tubes and batteries for these S2+ lights! And the Tan one…it’s reaaaally nice :heart_eyes:
Also, on this DT version (and maybe in the Clear version), the possibility to use the clip in the head of the light, is a nice feature especially to use the light in a cap!! :+1:
Yes, the reversible clip is nice. Although, in my experience, carrying an 86g light attached to a visor cap is not comfortable for extended periods of time - you can feel that weight and it causes the cap to sag. I tried it with my DQG Tiny 4th, which weighs 86g.
Right now I use OTR M3 which weighs 59g. That is about as heavy as I can tolerate on my visor cap.
Yeah…you’re right! It may be heavy for a long time use on a cap :person_facepalming: To be “hard” and “resistant” as a S2+ is, somethings must be sacrificed, namely weight (although they are not heavy “heavy”).
Still, even for “pocketing” inverting the clip is nice in some occasions!
(Hum, I thought about getting a OTR M3 through GB or AliExpress, but then I analyzed the UI and bought a Olight S1R…I’m waiting for it :nerd_face: )
Do the TIR lenses sold by Convoy work in the S2+ desert tan?
According to the specifications they’re 1.2 mm wider and 1 mm higher, but I imagine a bit of sanding might make them fit.
My understanding is that the XP-L HI in the desert tan is smaller than the XM-L2 that the lenses are designed for so they might work, but I don’t know enough to be sure.
I’d buy the great S2+ desert tan a few weeks ago 
But i’d see later, i could’ve orderered it with an OP reflector.
Now my long OP reflectors don’t fit the S2+.
So i’m looking for an solution, what do you guys suggest?
All TIR optics sold by Simon but one (the striped) come with a holder, so without the holder they all fit in the S2+
I’m not sure what you mean with TIR and the striped, but these are the ones i have:
Left OP is too long for S2, middle one is from S2 and right one is SMO
So where to get another copy of the short OP reflector?
You can get it directly from Simon.
Contact him directly with message on aliexpress
Yes, it terms of the dimmensions they will probably fit as Persechini said. You may have to sand a bit the plastic holder to make it fit perfectly, but they will fit, because the host is equal to a “normal” S2+.
But…here you have some images (click to open bigger photo):
The XPL-HI doesn’t fit perfectly on the lens, as you suspected! The XML2 LEDs fit perfectly on the holder and the Lenses. The XPL-HI has some empty margins in all sides.
Using the white gasket doesn’t help to center that much. The best option - at least for me - was to take the gasket out and use the TIR in the plastic holder.
The beam is not that bad, but it is not completely defined as in a SMO or OP reflector. It works.
Clear TIR 60º Lens - Produces a super “hot” hotspot and some spill. The hotspot is more intense than with a SMO reflector, and the spill is smaller than with a SMO.
Pebbled 60º Lens - Unlike the XML2 LEDs, on the XPL-HI, there is a “small” glimpse of an hotspot. Both “hotspot” and spill are floody with this lens. XML2 LEDs with these lenses give a more floody and homogeneous beam.
SMO Reflector (the original)
OP Reflector (the ones use mostly on the other S2+) - the hotspot is still intense, and it seems less defined a bit wider than on a SMO.
Hope this helps!!
On the right and middle there are TIR lens (clear surface, 60º; pebbled, 60º), and on the left, a reflector (OP).

About the OP reflector, as XXX-Man said, contact Simon through AliExpress store. Recently I ordered 2 reflectors and I wanted 1 SMO and 1 OP, and asked Simon for it.
You can also try to see if these reflectors fit (Kaidomain Store in AliExpress):

But the best option is to talk to Simon at Convoy Store!!
That was very informative and helpful. I’m definitely going to grab one of the pebbled 60degree lenses for an upcoming project.
Also, I added an OP reflector to my desert tan and I like how the hotspot is smoothed out a bit. It’s more like my Zebralight HI.
Thanks 
I hope it helps, despite this was made in a rush! 
Some days ago I made some “essays” with TIR lenses, on a S2+ XML2. Here’s the link, maybe it can help: Essays with TIR lenses on Convoy S2+: XML2 + XPL-HI [Update]
The pebbled lens is pretty nice for floody homogeneous beam in XML2 LEDs. On XPL-HI, a slight hotspot (blurred) can be noticed.
I like to use it with warmer tint LED (XML2 T6-4C)
Yup, the OP produces a larger but very intense hotspot, not sot defined as a SMO, but pretty intense actually!
BTW, Left to Righ:
S2+ XML2 T6-4C OP reflector > S2+ Tan XPL-HI U6-3A SMO Reflector > Modded SSteel light XML2 U2-1A SMO reflector
S2+ XML2 T6-4C OP reflector > S2+ Tan XPL-HI U6-3A OP Reflector > Modded SSteel light XML2 U2-1A SMO reflector
S2+ Tan XPL-HI U6-3A SMO Reflector > Modded SSteel light XML2 U2-1A SMO reflector
S2+ Tan XPL-HI U6-3A OP Reflector > Modded SSteel light XML2 U2-1A SMO reflector
At ceiling:
S2+ Tan XPL-HI U6-3A OP Reflector vs S2+ Tan XPL-HI U6-3A SMO Reflector
Interesting to notice than, in lower levels, the hotspot of XML2 LED flashlight with SMO reflector is as defined as it is with a XPL-HI. On higher outputs, despite having some hotspot definition, but being an XML2, it becomes wider and not so defined.
XPL-HI, also becomes wider on a OP reflector, as mentioned! It also produces a “strange” effect. When turned ON at max power (ex: level 6 of Biscotti = 100–20–1%) the hotspot seems to provoke a “fade”.
Meaning: my eyes tell me that XPL-HI using OP, when turned ON at max, seems to produce higher output beam than when using SMO reflector, and then “fades” and stabilizes and get more defined.
But, these are just my eyes, not an accurate measurement. I don’t have another XPL-HI S2+, otherwise I would compare side by side…
