Hi people. I am pretty new to this stuff, but was advised on a convoy at 1400MAH. I ordered the torch, but got the 2100MAH version( Which I gather is brighter, but will drain my samsung 25R’s quicker (I Think half power will be used a lot, seems bright from the vids I have seen).
I just wanted to know what model I have to go for if I want to get another at 1400 MAH, I got the Convoy S2+ Cree XML U2 - 1B 7135 x 6 8 -, which one would be 1400MAH?
Thanks, and regards, Conan.
Most Convoy models can be bought with different driver amps but not everyone sells them all. Fasttech has lots of options, use the dropbox to pick your options.
Ahh, I used gearbest could of been why. I’l remember fasttech for the future.
I believe you want the x 4 chips
We had a group buy awhile back. I had mostly purchased ‘cheapo’ as in really cheap lights so this was going to be my ‘best one’. Based on a lot of reading in the thread I chose the 7135*8 option (MORE POWER! whoo hoo).
Turned out that was a complete non-starter. You have to realize a lot of the guys in this forum are completely ‘power obsessed’. Functionally you can’t tell the difference between hi and med on a 7135*8 by eyeball. I tried. I tried real hard-outside, inside, ceiling bounces, etc. Looking back I’d pick the 7135*3, no more than *4. The rest is just a waste of battery power, turning it into heat. It’s a flood, not throw, and it simply doesn’t work all that efficiently with more power.
Other than that it’s a very nice light.
Including me. :8) 
:~
Are you saying you can’t tell the difference between 1amp and 3 amps??
I don’t know what the amp differences were but I couldn’t tell the difference by any visual observations I could come up with.
On my 2.8A S2 I can notice the difference between medium and high, but it’s not that great, possibly 20% more on high. What is noticeable is the head produced whilst on high. I would consider the 2.1A version (6*7135) ideal as it could be run on high for long periods without any heat issues.
I would assume that the S2+ would be similar considering the host size/design.
I would buy the 2.8A version and run it at 100%. Wait I already did, and its not bright enough. Yup you sure can tell the difference vs a 1.4A, but your eyes will adjust to whichever A and mode you want to use it on, not sure that 2.1A could be a problem in any way except if you’ve timed out an exact walk in the dark and need it for longer than you have the mAh in your battery for. Thats how I time things…but I usually just take more batteries.
If you don’t mind red, I’d get this one, run it on medium if you want extended battery: http://www.gearbest.com/led-flashlights/pp_154256.html Use code S2490 for a $12.99 price.
The human eye isn’t a very accurate yardstick for output since we don’t perceive a doubling of lumen output as a doubling of illumination. It takes several times as much light to seem twice as bright. Even cameras are easy to deceive if they simply stop imaging once a certain amount of light is received. I could well be wrong but my perception is that throwers are more likely to be perceived as significantly brighter than flood beams since the extra output is more concentrated.
Hang on, that will be great if it is that bright that the middle power mode is enough! Longer battery life also, it is only because the only flashlight I have is a keyring one which was from the £ shop and is rubbish, and I vape so have a few samsung 25R batteries spare, so thought I would get one of these.
It will only be used for when I drop things in the dark and the odd middle of the night walk ( Our streetlights get turned off between 1AM and 5AM, so it is pitch black out there, if the moon isn’t out you really can’t see)
I guess the 7135 × 6 8 is the power part? So I should of chosen 7135x 4 instead? I may buy another for my mum, but we live together so there is not much point. Next thing I am looking for is a keyring torch that actually works.
What will the battery life be like? My batteries are 2500MAH samsung 25r’s, any ideas for mid and full power?
Sorry, but I disagree. There is a HUGE difference between High and Med output modes on the 2.8amp (8*7135) driver. If you can’t see the difference, then you either have something wrong with your eyes, or something wrong with the torch.
What batteries are you using? It is possible if you are using crappy Ultrafire batteries, that they simply can’t deliver 2.8amps, so it may not end up being any brighter. But this has nothing to do with the driver, torch or it’s potential.
Have you checked tailcap amp draws with a DMM?
25R’s are great batteries, but better at high output shortish runtimes. If you plan to use lower outputs or a lower powered driver like the 1.4amp version. Then a higher mAh battery would serve you better. An Efest purple 3100mAh for example. Or even some of the high capacity ICR’s.
What do you mean by “6 8” there?
I’ve already got the 2100MAH one coming, I ordered it 3 days ago on the recommendation of another forum, but the recommended the 1400MAH one but said the 2100MAH will be fine, just drain batteries slightly faster on high(I will probably use half mode most of the time, as that will be the same as their lowest 1050MAH version they do on full brightness lol).
If I do get another one for my mum, I will see what the 2100MAH one is like before I order it, although I will more than likely get a good, but budget, keychain torch instead.
I have no idea lol, I copied and pasted the description from where I Bought it, although it does say in the full description 2100MAH.
The headline description was “Convoy S2+ Cree XML U2 - 1B 7135 x 6 8 - Mode 940lm Highlight LED White Flashlight”.
My guess is 2.1Amp driver (7135*6), 8 modes in 2 groups (group 1: LMH without blinkies, group 2: LMH plus blinkies)
Yeah I can have it 3 settings, flashing and sos, or just low, medium, and High. Must be that.
