Got the T6 sft40 3000k, amazing pocket light, even with AA batt🥰
I 've got the T6 cslnm1.tg. It 's a pocket cannon! Very fun to use!
I wish it wasn’t a FET driver for the 14500. Otherwise it seems like a fun toy.
I thought that the new 5a dual fuel driver is a Buck/Boost.
And if that’s not the case, it uses a 17mm driver and I’m sure Simon would install a 5A Buck driver for you.
I was just going by the information in the product listing, which states FET for the 14500 and buck for the AA.
Unfortunately descriptions on the Convoy store often lack accuracy.
Here’s some sort of refutation of the driver being boost+fet.
And here’s a discussion about it is actualy a buck+boost
I’m glad to hear that it’s not FET, and I remain puzzled over the inaccurate product listing. I guess we can chalk that up to Simon being overworked with the move on top of normal business.
Can anyone help me understand what the main differences between all these different driver options being talked about and why people are so passionate for and against certain ones?
I have no idea what the benefits or cons are to determine whether I should get this light or not.
I don’t know what I need to know and don’t need to know.
I don’t even know what I’m asking.
We’re all happy to help figure it out together. This light’s driver is a little more complicated because it can take a ~1.5V AA battery or a ~4.2V li-ion. We know it is a boost-and-something driver because it needs to “boost” the 1.5V from the AA up to ~3V to get the LED to turn on. The question is how it works with a li-ion.
You hear a lot about buck drivers these days because we enthusiasts are getting a lot of our other demands met (519A, Anduril, etc) and we’re running out of things to complain about (kidding).
IMO driver efficiency is but one of many characteristics of a light it alone shouldn’t dissuade you. Regardless, it sounds like this does have the “better” driver so it’s a moot point. I think it’s a going to be a great light.
I’m so lost at this point I don’t even know where to begin to explain where exactly I’m at to help you/BLF help me. To make sure I’m actually getting help where I need it and not just hearing things I’ve already heard many times, or stuff that’s way too advanced. And here probably isn’t the spot to try and do all that.
I should start some thread of my own but I’m also just horrible at trying to communicate clearly and even worse at in this text format and end up really overwhelmed. Like I said, I don’t even know where to begin.
I want to use turbo a lot. Only usually short bursts under 1min.
Especially with throwers.
I only have access to “included cells” that are presumably not as good as all the recommended “quality name brand” cells such and Molicel, Samsung, LG… And I cant actually know anything about what their actual specs and ratings are. Meaning I have no Idea what kind of turbo usage they’re “capable” of or when I’m taking any type of “risk” or using my cells “dangerously” or just in a way that is just really “bad” for them.
It seems to me like maybe I need to avoid FET lights?
Edit: Lmao, except now what I’m reading suggests the opposite!

" (one thing to be aware of - a buck or boost needs to have good protection against overdischarging a battery unless a protected battery is used, because many buck/boost circuits will happily overdischarge li-ion batteries to dangerous levels if the light doesn’t shut off at a low voltage)."
Making a thread of your own is probably a good idea. So are you looking for a flashlight recommendation or just have questions in general? And it sounds like you have some prefectly valid questions about bettery safety. Perhaps think about what you’d like to ask about and rattle off some questions in a new thread. Lots of knowledgeable people will be happy to help.
It looks convincing. I imagine there is nothing similar, having three more little things: spring on the headend, on-board charger, and an easy (auto) battery level indicator :-)
Is the switch on this light mechanical?
Yes, always!
It definitely uses the t3 boost/FET
Yeah the reason boost can ruin a battery even worse is because they’re capable of running the flashlight even when there’s not really enough voltage to do so because they’ll just convert the remaining battery energy to less amps at a higher voltage.
The Convoy site says:
Boost constant current (AA battery)
BUCK (14500 lithium battery)
With all due respect to everyone, I think this is just going to confuse the matter. FET based lights can ruin cells just as well as boost or buck. I recently had a D4V2 (FET) take a cell down to 2.2V with the aux LEDs.
It’s as simple as this, @CRC2 ,and most people (myself included) , should get a light that has low voltage protection (LVP) built in to the driver.
