  • 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
  • Good driver for the modernization of the flashlight

    Well done soldering.Good stabilization of the current at the specified range of supply voltage.Seamlessly cooperation with LED CREE XM-L2 U3
    Little short cable for flashlights witch variable focal length. When soldering thicker wires is needed soldering iron with temperature stabilization. There are likely to damage the driver.About 40 minutes of operation at full power on a single low-quality battery 18650
    Nice to use product for hobbyists that you can change parameter of your old flashlight.
  • Works well - as advertised

    A true constant current board that accepts a voltage up to a full Li-ion battery of 4,2 or a little higher for the exotic flavours of batteries.Also good with 3*AA rechargeables but dont expect to get the full 2,8A to the led.Dont use with two Li-ion batts though. It will cook and burn and fail and it will smell. Dont ask how i know ;-)
    Versatile and powerful but does not have enough low and medium modes for modern high powered flashlights.
    Great little boards.
