  • nice 2100mA led driver

    posted by yrnkrn

    Cheap price and works well. Can easily drive five, six, seven, eight XM-L in series with 2300mA current. It can drive nine XM-L as well, but the current is lower at 2100mA which indicates this is just a bit too much.
    As usual, output wires are too thin for this current.
    Nice driver, buy it.
  • it was delivered broken

    good driver. he provide about 2.5 amps to XM-L LED at maximum mode serially connected to a fully charged 18650 in maximum mode it takes about 1.2 amps. when the batteries run down, the current increases to 2 amps. I measured it all the bad in bad multimeter probes.
    The driver selects to replace the flashlight scu 126,256. he is well fit for the old driver, but had to do some work with a file. driver produces the sound of the second mode, the first mode, it is not audible
    good driver
  • very good reliable driver

    - easy to use- easy to solder- delivers 1.4A to led- 1 mode perfect for simple designs and retrofitting in old lights.
    easy to solder. small diameter fits in many old lights. perfect for updating old lights. straightforward use. no problems with soldering. I used it for an xml led and it delivers 1.4Amps to the led. The use was with no problems and the driver works without geting too hot.
    nice driver. veru useful. easy to use. I expect a 1-mode 2.0A version...

    +Small diameter+Quality PC board;+Good looking:)+Well soldered;+Accurate specifications;+Comes with soldered wires;+Good efficiency;+Good diameter for most 1AA flashlights;
    Can be sanded to smaller diameter.With 2 AA batteries the modes work perfect,bright enough and the strobe is very good(not too fast).It's perfect tactical led driver.Always starts on High,Medium is very good and the strobe is excellent.Watch my video!
    Will be good if the board works properly at low voltage-1AA flashlights are more popular than the 2AA flashlights.Probably works well with CR123 batteries 3V.
  • nice driver for several uses.

    sure , you can use them for Cree leds etc.But the single mode makes it possible to use them for other functions too.I have used them for 455-445nM laserleds, those nasty bleu powerbeam LD's with over ONE WATT bleu laserlight.Those laserleds can easily be destroyed, this PC prohibits this and crank your LD up to its max without obvercurrent.
    You have to use them with LD or leds wich are in voltage near white powerleds(3-4V)Almost no heating up or instability in current.
    Nice PC for inventors, in theory you can put them parallel but diode for safety is advised.
