3.6V 5-Mode 3W Circuit Board for Flashlights (1000mA 3.7V Output/2-PCS)

Pros: nice and cheap ive ran it on 4.5 volts with a cree q5 xre. the different modes are pretty good.

Cons: dont know if it ouputs 100mah but the cree emitter is still pretty bright. im new to flash light modding so i cant really elaborate on that. i dont think it regulates the current.

Other: cheap circuit board for flash lights!!!!!

Pros: Does what it's supposed to, lights up an LED from lithium batteries.
Has five modes, high/low/slow strobe/fast strobe/really slow strobe.
Runs cool, even pumping a low 70% to the Cree Q5 LED's, they still get brutally bright.

Cons: Doesn't provide 1000mah, and really, it never could with only one transistor.
The best one draws 700mah from the battery, and that's the one that broke partially. The other chip draws 600mah.
It worked a week, and then strobe and low modes stopped working, it "pumps" in a strange way on all but high mode.
Low mode flickers considerably, <60hz and isn't really useful as a flashlight if the flashlight needs to be a worklight.

Other: It pretty much does what it's supposed to, albeit the specs are exaggerated, the five modes do work as intended.
It provides a LOT of light, even when not pumping enough to a Q5 LED.
In short, it works pretty well for a cheap and small device.

Pros: Well It was easily sautered in because it fits in a AA pill esp. Romisen G-2. The mode is a bright high maybe 700-800mA and a low maybe 350mA not to low though as i would of liked. A slow strobe, then fast strobe, then that annoying 10-sec beacon yes 10 second not SOS. Its a 3.7volt input, I tried 1.5v no luck oh well. I tried this one after another driver with the brass spring broke (IC Chip underneath broke it was 17mm)

Cons: Limited voltage but try a 14500 and it will work great. Looked thin almost transparent but works great.

Other: A good driver definately close to advertised "1000mA". Try it you'll love it. 5 modes better than 20 modes simple and no need to sand down even fits AA pills by depth too.

Pros: I fixed a no name creee torch wit this driver,
5 Levels high,med,low,strobe,sos ??
my one drains about 1000mA/4.0 Volt on cell
(really!,checked with new Fluke DMM)350 mA in med,about 50 mA in low mode,as bright as the former 5 W(?) driver.
I use it with unprotected 18650 cell.
Will order some more,!!
small size,(one board only,Driver with 2 Boards would´nt fix in my torch)

Cons: Modes not like advertised ,(not a con for me)
atttached cables feel cheap,they´ll use a kind of silicone cable, but once installed,not a real con.

Other: Buy it,if you have to fix a flashlight, cheap driver,hope it will last longer than the Original.
