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

:slight_smile:

I’ve just received my blue S2+. Looks very nice, very bright, first convoy I have.
However one thing disturbs me a bit - sometimes I can’t change mode when pressing button just for a part of a second - it stays on the same level. When I press button little bit longer (let’s say half of second) - mode changes and then very short press can change the modes further. When I stop on some mode for a while - again very short press does not work and need to be used “half second press”.

Is that something typical in this light?

I think it has more to do with how long the light has been on in that mode, and not so much to do with how long you press the button. It’s not a defect, just the way the Nanjg driver was designed. It’s what we call “On-Time” memory.

Thank you very much for the explanation pilotdog68! :slight_smile:

The metal button was too tempting, so I ordered a green S2+ with a T6 3B + 7135x6 config from Simon’s store. And I also god the nice clip (seems better in quality compared to the old stainless steel one with the screws and nuts that secures in the tailcap wing).

This is excellent! T6-3B LED and 6x7135 driver. The tint is so nice compared to the bluish 1C. Needless to say, I’m really amazed at the output (this is my first 18650 light) and machining quality is excellent. The new clip design is pretty nice, allows for deep pocket carry. and can be placed on 3 different locations.

With a 8x7135 driver, roughly how long can the S2+ be kept in high before it gets “too hot”?
(In warm ambient temperatures).

Does anyone know what the metric thread count is for the S2+? It's super close to 20 TPI SAE but it's obviously in metric.

The Blue S2+ has a 1.25mm pitch though its not a V thread. Its more a type of acme thread.

S2+ has a 1.25mm pitch metric thread. It is a 60° V thread, just truncated. (tips are cut off) You can cut the threads with a standard 60° threading tool.

Where is everyone buying Convoy products these days?

Here I guess! http://www.aliexpress.com/store/330416

Thank you sir! I replied weeks ago but apparently didn't post it properly ;)

When people say they are buying directly from Simon, is aliexpress the method to do that?

Yep… it is Simon’s shop.

Hope someone can help me sort out my S2+ dilemma.

I am trying to figure out which model to order from either Simon, or any other place is preferable?

I definitely like the metal tail switch, I am not such a big fan of the green/orange rubber ones.

Looking at the store, only the RED or BLUE lights have the METAL switch right?

It’s not easy to navigate Simon’s store there are just so many S2+ models.

I think I prefer the brightest possible light, so I guess the 7135*8 chips

and the U2-1A tint would be the brightest?

Thanks for any suggestions,

Depending on you use, the 8* version could be too powerful, making the lower modes not very useful for extended usage. My advice comes from using the light as a tool and not as a bunny burner or toy.

I have the 6* version and while at 100% it’s nice and bright, it takes less than 1 minute for the head to start heating up noticeably, and at 3 minutes the light starts becoming uncomfortable to hold. The 8* will be even worse, especially since brightness does not linearly scale with current after some point, and the two extra regulators will heat up too. Note that the driver of the light has no thermal limiting so temperature will keep rising if left unchecked. I would personally get the 4* version if I could go back in time.

Tint is preference and 1A tint falls into the most efficient U2 bin. Note that it’s quite bluish and green outdoors nature will lack contrast and be suboptimal. I like the 3B tint for general outdoors usage, it’s neutral with a very slight greenish tint.

The metal tail switch also comes with the green color. It’s a shiny desaturated green that I think looks good and is not very flashy. Simon’s shop on Ali is the best source I think.

the 7135*4 gets not too hot if left alone on high

tested that at least 3 times with mine in warm summer nights

I am pretty sure the 7135*6 will damage itself if left alone on high with a good cell

With a (not so “fresh”) Samsung 25R, my 7135*6 S2+ reached 80C on the head after 10 minutes (measured with contact thermocouple) at tailstand orientation.

I don’t think it will damage itself.

I only have the 8*7135 Convoys and I run them on high a lot. They will get hot to touch, but are fine. LEDs can actually take a fair amount of heat. The 6*7135 really isn’t driving the LED all that hard.
