1. Constant Current

2. Battery reverse protection

3. Low voltage warning
When the voltage is below 2.8V, it changes to Low mode (1 ma) and flashing every 60 secs.
And the cut-off voltage is at 2.6V, LED will be turned off. 

4. Memory / Non-memory function 
Easily configurable by setting the output group.
Dimension: 17mm (Dia.) x 1.6mm (Thickness of PCB) x 4.8mm (including all component)
Weight: 5g

* GND (the outer ring - either side) must be attached to metal with thermal eproxy to heatsink.
Optimal heatsink ensure constant regulation without thermal protection kicking -in (i.e. reducing output).

** Warranty does not cover user damage. Please make conduction test before connect to the LED.

Four new types of mode is revised in V4 version:
1. Lo Med High AUX1(2Hz Blink) AUX2(S.O.S)
2. Med High AUX1(100%) AUX1(35%)

Ownership verified by KD Good 3A driver

Two Matching bodies, XM-Ls,fresh Batteries gives me a typical 2.78A With 105c driver & 3.05A with this Driver. Seems to maintain higher Comparative output as voltage falls down towards 3.8v. A little easier to solder leads to than 105c. Has "firefly" like low mode. I like having memory as optional.


S3 bridge may be listed in backwards order?l/m/h, h/m/l. Had some leaching & crud formation around the S1 to S4 Solder pad bridging area? I miss having a standard low mode. Hope you're not expecting standard green circuit board material.


Solder connecting S3 gives me H/M/firefly(low).......haven't tested Memory yet. I like it like this as a semi-tactical 2 1/2 mode(so to speak)......

This version is probably the cleanest and best made that I have seen. Larger soldering points is a big plus for me and my "all thumbs" hands. Setting up modes is easier than before and having the instructions sent with the board is really icing on the cake, compared to previous versions.


I have not found any. The only thing I would like to see is that the spring not be there. I never use a spring on modded lights. I always solder the +wire direct, so I have to remove the springs each time. Maybe it could be optional or just come in the package with a spring.


Overall it's a great board at a great price.

На свежих батареях дает 3 ампера! Можно отключить дурацкие мигающие режимы. Установил в TrustFire Z3.


Слишком слабый минимальный режим. Таким только если на часы подсветить. Очень тесная плата - недобно провода припаивать.


Идеальный драйвер для маленького прожектора!

- really giving 3A with fresh battery - larger soldering points than nanjg 105c - optional memory mode (see cons) - mode groups


This is good linear driver but it has 3 big faults: - when memory mode is OFF and you have set 3 or more modes: Flashlight is on, you select second mode, stays here 1 or more seconds, and when you want switch to third mode, the ligh goes first of all to first mode and you must quickly switch over second to third mode to select it. - for switching the modes must first click be doubleclick. Why? - unusable low mode. 50mA version is good.


Instead of having option to set unusable blinking modes, i would like option to set 4 mode of 10mA, 50mA, 500mA and 3000mA.
