size:Diameter 17mm, PCB thickness 1.7mm,components 1.6mm high
Protection:Reverse polarity protection, low voltage protection, mode memory function
input voltage: 3-4.5V
output current:2800mA
Suitable for the LED of type voltage 2.8-4V
Modes(2 groups 8 modes)
Group 1 (5-Mode): Lo (5) > Mid (40) > Hi (100%) > Strobe > SOS;
Group 2 (3-Mode): Lo (5) > Mid (40) > Hi (100%)
How to Switch the group?
switch to low mode and wait for 5 seconds. As soon as you notice a quick blink, half press the power switch and mode group is then toggled

Simon has already answered your question …
(if the emitters are the same )
your 6x 7135 chip driver is running @2100ma on high and 40% of that is 840ma…
So you medium on your Convoy S6 will be a little dimmer than a 3 chip led light would be ….then factor in tint loss either way .
Lo (5) > Mid (40) > Hi (100%
I’ve always wondered why people just don’t buy a driver with more chips and snip a leg on the 7135 if they want less .
Seems it would be way easier to just resolder a snip than add a chip.
Visually there isn’t much difference between high and lets say 50% That’s why Chinese vendors who make bad flashlights with cheap drivers are really pretty clueless as to how to make good mode spacing . * It takes 4 times the increase in brightness for our eyes… (brain) to perceive a doubling of power .
The middle leg is a ground pin(whose pad is often not connected to the ground plane)and since there’s also a ground tab snipping it is pointless but snipping either of the end pins would disable that chip. One end would disconnect the output and the other the signal turning it on.
Just compared my 7135x6 neutral white to my 7135x8 warm white Convoy S2+ The warm white S2+ is noticeably brighter even though it should be dimmer if the same driver was used.
The bottom line is the x8 is kickass, but battery life will suffer compared to the lower output drivers
My first Convoy was a S2+ with a 7135*3 Nanjg because everyone said not to get the 7135*8 because it would overheat and I wouldn’t notice the difference. I liked it, but it never wow’d me, so I didn’t use it much.
After awhile I got bored of it so I added a Noctigon and a 7135*8. This really made me fall in love with it. To me, the difference is pretty noticeable.
Now I have few S2+ lights with either an LD-1, FET + 1, or 7135*12 Nanjg drivers with custom firmware. Yes of course they get hot…but when they do, I just use a lower level. When efficiency is needed, I use the one with the LD-1.
My S2+ (or in fact my wife’s ) had 6 chips
But she just kept on using it on high and thought it got too hot
Then I wanted to make it cuter with that 18350 tube so wanted to get longer runtimes and de soldered two chips
It still gets warmer then I like so I am going to remove one if she complains again.
Yes it is less bright but with the tir optics it is not much.
The water argument would be correct if you could run a flashlight at any output level mode you want at any time, just like turning the kitchen tap until it spits as much water as you'd like it to. That's not the case. If you buy S2+ with 3×7135 you have three practical modes, if you buy one with 8×7135 you have two practical modes and an overheating turbo you'll almost never have a use for.
(Some people also like a low mode of 20 lumens, not 50, but that is a preference)
I am good with the 3x or 4x 7135’s in a tube light like the S2+. I did a build thread on 1.4A triples HERE if you want to look at some comparison beam shots. It is not direct, as these are triples, so there is a little more light, but not much. It may help you decide between the 1A and 3A driver.
In all practicality, if you want runtime and a good amount of light, the 3x 7135 at 1A output will do great, and your lower modes are proportional (i.e. 5% of 1A or 5% of 3A) so they are more usable as well.
If you can solder, or have someone that can, I would highly recommend a driver from Richard at Mtn Electronics ( 1A 3x 7135 ) flashed with guppydrv universal will give you all the modes you could want for a driver, and has some very nice low modes too.
Max amps are great when you need them, but for the most part, a 1A driver will get us along just fine and give out plenty of light while giving a cool, long run time on high.
Does anyone know where I could buy driver with guppydrv - but with free international shipping? I’m in Europe, so mtnelectronics is not an option for me…
I think the best options for you would be having them in 7135x6, running Biscotti. That way you can set them on 10% or 50% modes (they work great with a diffuser), but if you need more power out of them for whatever reason, you can just program them into a mode that has 100%. Biscotti’s versatilility is just unparallelled as far as “vanilla” Convoys go (because Narsil, Bistro, guppydrv or whatever are on another level entirely).
I also say that because I have an S2 running 7135x3 on the 3/5 firmware, and man, it’s not worth it. It’s not worth it and I hate it despite loving the form factor and beam pattern. Can’t wait to mod a new driver with Biscotti or whatever else that isn’t the bloody 3/5 onto that one.
