  • 3*7135 chips

    7135 chipsRegulatedMemoryReal output advertised
    This regulator drive out fairly steadily 1.4 amps. in max. mode.Exactly: 1.35 in high mode, 0.4 in middle, 0.6 in low (fluctuating in sos and fast strobe modes).I have put it, working together with a 16 mm alu base Cree R5 led in my Trustfire TR-801, and it bright now 25%-30% more than the original Cree Q5 led, giving a really flood light!According Cree data sheets, Cree R5 can hold up 1,5 mA, so this regulated circuit is perfect to this led. Other drivers that can only drive up 1000 Ma, will give 25% less light tan this.
    I recommend it

    +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.
  • Quite decent. Does what it says

    Drives over 2,5 amp. Pieces look quite sturdy so it should last some good time.Good voltage input range. Using it on a vehicle for offroad light, so up to 18volts looks fine.At 12 volts and less it drives 2 series XM-L, possibly 3Get hot, but does not get *too* hot3 modes... I'd count it as a Con, but it is what I've bought, and already worked that around.
    none at the moment...
    Works well, check it first, put sturdy wires.Good solid circuit for your mods.

    Small and very useful LED driver circuit board.Can be used for any DIY project flashlights;Easy to mount it in small flashlights;Just ON/Off,so no problems with strobe or SOS modes.Suitable for 1AA/1AAA flashlights;Well regulated;
    Excellent board on excellent price.Good to have it. Recommended buying.
  • 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.
