+Puts out a nice ~2.8A on high
+Works fine in combination with a standard M*g switch. (you only have to get used to half press to select and full click for confirming modes) -Fragile, wire between 2 boards got a bit mangled during shipping, Silicone led wires are almoost too fragile to touch.
-Rather noisy (but only because I use it in absolute silentness ... Read more
This appears to give as much current as most other cheap drivers for P7 etc, but it does appear to be lower than rated. I think the two Shottcky diodes are connected in parallel to allow current handling of ~4A This thing is bulky and runs hot, C1 blew on my example trying to run a P7 with two 18650s in a M*g 3D. I am going to amputate the secondary ... Read more
It will take various voltages and drive the LED properly.
Modes are out of sequence but there are 5 different ones. "Strobe" isn't. A strobe is normally a very short but bright pulse like a xenon flash unit. Instead this is 50% duty cycle.
I don't know if any are really high-med-low-stb-sos, mine appears to be med-low-hi-stb-sos.

Wide choice of modes. Good price 1. I think the output current is overrated. Mine was able to produce max. 1.9A on the output, using 1.3A on the input (see other thoughts)
2. The real problem with this drive is as many of you noticed it gets really hot - I reckon too hot to be enclosed in a casing. The switching transistor is the hottest and needs cooling.... Read more
5 mode are effectively when you need, except the strobe and S.O.S. I had made this for my computer desk lamp connect with two Q5 emitter in series and cooling fan. Exactly what I need and convenience. Save a lot electricity then regular lamp. It does not has memory, always start at MED-LOW-HIGH-STROBE-S.O.S. That is fine with me, most the time when ...
