Left hand thread for the switch ring or driver ring is not uncommon. Keeps it from being loosened by the body turning against it.
Well as I mentioned above, my first S2+ was 7135*3. The second was 7135*4. The red one I got was 7135*8. So I had a $2 credit from DX. And they just sent me a CC for another $2 because an order of 14500 batteries from back in Feb/Mar was screwed up. So that gave me $4 to spend. So seeing how I had a *3, *4 and *8….
I ordered a *6 in grey with $4 off so this will be the least expensive one so far. :bigsmile:
And because of this Dave, you will be the man for all of us to ask in the future 
Thanks,

Just give me the usual 3-4 weeks till it arrives :bigsmile:
Actually they mentioned their slow/unreliable shipping in the CC email. They said they’re trying another carrier to improve reliable shipping. We’ll see……
Wider angles are also possible.
Should these enhance throw significantly?
Have no personal experience (yet: order is on it’s way), but Simon of Convoy opened a thread about replacing the reflector by a TIR lens.
Looking at the foto’s I would guess that the main difference of replacing a shallow reflector by a 10 degree TIR is a “cleaner beam” with less spill.
I don’t think they increase throw, but just change the beam. The 10 degree TIR lens is $0.40 from LEDDNA. I really like that one in the S2+…beautiful defined large hotspot with a nice wide even spill.
By looking at those pictures, 10 degree lens does look to be brighter.
Would love to get my hands on stripe TIR lens as well.
Has anyone successfully removed the bezel from the S2+ ? I’ve tried 2 strap wrenches without success.
Thanks,
Mike
Bezel . . ?
There is no bezel. :~
Lens, reflector, led, pill and driver are all removed from the inside by unscrewing the pill / driver.
Carclo is a well known type of “TIR”. Optics For LEDs | Tir led lenses It seems possible to dig out from there how high the optic device should be over the LED. They list where to buy. I don’t know (yet) if any will fit the Convoy.
They are not pure TIR. They are really combinations of reflection and refraction, like LED Lenser and Fresnel lighthouses. That is, there is a hollow over the LED with a lens over it to focus the light that comes up the tube. It should, theoretically improve the fraction of the light that goes into the spot, by focusing the spill as well as the reflected light. It probably should increase the throw, by reducing the dark ring around the LED that one seen looking into a reflector light in moonlight mode.
Not significantly no. Although I think you might see an improvement, I always think the DQG 18650 Tiny with it’s TIR throws a beam very well for it’s size and output.
But significant, no. Throw is about reflector size, and the S series lights are all small in diameter terms. LED size in relation to reflector size will be the main way to increase throw. So swapping in either an XP-G2 or XP-E2 will give you a much tighter hot spot and more throw, but less lumens overall.
Personally I like the XP-G2 in this size light, as you can still drive them at 2.8-3.0 amps without excessive heat issues. So it’ll still make a lot of lumens, but will easily out throw any XM-L2/-XP-L at the same current.
The XP-E2 you’d need a lower amp driver (probably under 2 amps). Much smaller hot spot, but also a lot less lumens. If you want the beam profile to be narrow, then this would work, but I think it would be less useful than the XP-G2.
Of course you could look at de-doming. This works for any emitter. And will increase throw, but can cause unwanted tint shifts.
All of the above is also true for a TIR lens.
TRANSLATION OF THE REVIEW
Excellent lens. The quality of the mark, come quickly.
Probably not 10g., And 15.
Yeah, thanks for info :D!
I understand that reflector size vs LED size is the crucial part here, however wanted to see how much better it could get with just a TIR lens.
Now, still waiting for it to arrive, so will see how good it is once it arrive, Im sure it will be just as good unmodded :D!
I'm using diffuser film on these type lights more and more .hard not to appreciate pure ultimate smooth flood ..for them that like the flood of these shallow reflectors I'd think smooth diffused would make lots of you very very happy.
Will the blue version have the metal switch button? Anybody see the blue version for sale yet?
Because there are so many fakes/clones of stuff out there, where can we buy one that’s genuine? I know MTN carries the real deal, any China sellers?
I’d probably just buy from MTN if he had blue.
Buy from Simon’s aliexpress store. Link in Simon’s sig, see OP. He accepts paypal if you msg him.
I’ve placed order from Fasttech for this on early Feb. It shows “Restocking”. Is the manufacturer (Simon of Shenzhen convoy) being swamped with backlog?
