High current drivers for single XM-L2

Yes I’m testing one now in a thrower project. I tried it with an XML2 and got 5.5A and also 5.2A with an XPG2 >) both on sinkpads. The xpg2 died after 10 minutes of shining it around the trees. The XML2 worked up until I dropped the light on the concrete floor. it never worked again after that.

I just saw this yesterday, no firsthand knowledge.

Looks like this driver from IOS

But in 5 pack. Nice price! :)

I though it started life as a 3A driver. Then IOS modded it to 3,5A. Now its modded to 4,5A. Does anyone know how much further it can go?

Edit: And that is also the same as the FL-2 from LCK-LED??

Edit2: LM seems to have it as a 3 amp version too.

And they have both the 3 amp and 5 amp version in 3 or 5 modes.


Thanks, that is useful information.. Did it have any PWM whine?

I wonder why the XP-G2 died.

I have a driver (stock driver in STL-V6) that is adjusted for close to 5,3A. Will combine it with an XP-G2. That might be able to do 6++, but I have not pushed it that far (yet?), but its not available from any stores..

IOS 9A has a huge pile of 000 resistors, should be easy to remove them all and add back until you get what you want. No clue about the stupid overheat protection though.

Do you have an FT link for the correct East-092 version? The one I see on FT doesn’t show it back in stock.

They’re not selling any version, 2A or 4A. What am I missing here?

What you're missing is the part where it says 'in stock' and you can add it to your cart. They just haven't removed the note at the top of the page yet.

Thanks Racer86 for starting this thread. The 21.6 5A LCK-LED driver is the same as the 4.5A IOS driver - identical, only difference is the resistors, so it must be very modifiable by resistors. I got both side by side - clearly the same driver. the LM listing specs and left side photos match this driver as well. I don't understand their photos though showing 2 different parts: lightmalls-5000mah-3-mode.

I'm new to this so please bear with me. I have an UltraFire single 18650 cell light using this bulb. What would changing the driver do and how easy is it to change drivers?

Hi, on most lights its fairly easy to change the emitter. (Atleast when you are used to doing it). The main reason for changing out a driver can be:

- Increasing current on high

- More or less modes, with or without blinky stuff

- Better mode spacing

- Getting moonlight

- A more advanced UI, programmable, hidden modes, battery indicator etc...

- Less PWM, not visible or audible

- Better efficiency..

- Better memory

- etc...

This is not the thread for your light though. This thread focus in maxing out the XM-L2 in larger lights using two batteries. This might also require modifications to the driver circuit. Using copper mounted emitter etc.. This thread is about taking the XM-L2 to the extreme. The emitter is rated for 3Amp max, which for most is a lot. Here I am looking for drivers that can be modded to do 6A+.. J) Or generally, just getting of list of extreme output driver circuits.

Read around on some build threads, stickys and stuff. That will give you some basic knowledge. In many single emitter lights (using 17mm driver circuit), a Qlite driver circuit is a very nice and simple upgrade. Make a thread about your light if you need help modding it...

hmm.. good catch. I can not comment on the difference though. One light seems to have a large toriod and another picture uses a small one. Maybe others know more..

3A version small toroid, 5A version large???

I swapped back to an xml2 on a sinkpad. However my driver must be defective, it only has off and on, no other modes. Now when it came in the mail it was broken squashed flat. I soldered it back together used it and forgot it was supposed to be multi-mode until you just mentioned it.

Well, a single mode driver pushing 5A+ isnt the most practical driver. Did it come from FT?

Btw, when I read the part you have quoted me on. I have no intention of pushing an XP-G2 to 6A.. Only a bit more than 5 amps.. 0:)

But my STL-V6 driver might be capable of 6 amps for all I know.

Does anyone know if the manafont TR-3T6 driver can be used with a single XM-L2 and if it can do 5++ amps if modded?

The driver came from DX

Planning a build on an M8, will see how these stack up. Thanks!

RaceR86 - sorry didn't get back here - yes, from what I understand the bigger inductors are part of the circuit design for handling more power - amps.

Damn - the more I think bout it, the more I like that LM deal for the 5 pack - I bet the 5A version is with the bigger inductor pictured on the left, while the one on the right is the 3A version... I've been paying $12+ for the IOS one, bout double the price..... ugh

Tom, did you pull the trigger on the 5-pack?

Some time back I tried to increase the output of the 5A IOS/LCK-LED/Lightmalls driver. But with my very limited testing, it did not seem like it wanted to go much beyond 5,2A (output actually got lower if I tried to increase a bit more) I decided to leave it stock. If others have tried to resistor mod these to more than 5A, please share.. :)


I have updated OP a little bit. Added the TR-3T6 driver.

No, but still got the IOS 4.5A an LCK-LED 5A. Someone or 2 did order the 5 pack. Thinking the 5A version is the big inductor, 3A small.
