Review: Convoy S2+ (the red one!) – Fantastic 18650 EDC

I agree, it’s pretty substantial and 50 lumens is enough light to do quite a few tasks.

Ordered on May7, arrived today - a week after my knife order placed on May20!

This is a nice FL, too bad I promised it for SO. Shoulda ordered 2.

I wonder where the blue one is. Bought a red one for the wife. I’d like one for myself if there was a blue one.

YES - I want a BLUE one in 1A, please!

Thanks,

can you try to cook your red S2?
just for know how color it will turn

I have an S2+ recently bought from Shenzhen Convoy Electronics Co., Ltd. on AliExpress. It was slightly on when switched off. I took the switch out with considerable effort. It turns out that the ring holding it in has a left hand thread! Very strange and user unfriendly. I didn’t see the problem and didn’t take the switch apart, but the problem went away when I put it back together.
Aside from those two things, it seems perfect for what it is.

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 :slight_smile:

Thanks,

NP :slight_smile:

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.
