|Input:||2.7V - 4.5V ( 1 x Li-ion or 3 x NiMH / Alkaline battery )|
|LED Support:||Cree XM-L / XM-L2 / XP-L / XP-L HI / P7 / SST50, etc. (3 x XP-E, 2 x XP-G wired in parallel)
|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)
* 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%)
3. AUX1(100%) AUX1(35%)

Strengths:Many options for customization Flat regulation and efficient operation on single li-ion cell Good build quality
Weaknesses:Slightly more expensive than a regular amc based regulator board.
Summary:This is the best regulator to get if you want options, short of programming your own micro-controller.
Strengths:Good quality PCB, soldering is clean, large (for manual soldering) pads for wires. Max current is ~2.2A as stated, good for a small torch - not stressing the LED at max. Low batt mode realy works, triggers at 2,87v approx, can be handy in some situations. Comes with a clear instructions for programing and 2 small wires for the LED.
Weaknesses:Low mode is TOO low, just like a true firefly :) I cant see any real-life use for this, would prefer 30%/60%/100% version instead. So its limited for 2 modes actualy - HI/MED and various blinking.
Summary:Good versatile driver for a reasonable price. Perfect choice for a small torch, I gave it 4* only for a useless firefly mode.
