  • 3*7135 chips

    posted by espimones

    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
  • 3-mode LED Driver

    +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.
  • 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.

    -easy to use and great to look at.-easy to take apart.-great look.-LED's change patten.
    -buy it if you wanna give your 360 some styleor if your other HDD das not work.
  • Works with up to 6 XML's

    posted by valdasbiel

    Driver board is suited to work with 4,5,6 XML's connected in series with output on high about 1~1.2A. It has three modes on cycle press and hidden flash. You can set any of three modes choosing from 10 levels of brightness. It has low voltage warning turning red status on.
    For better use with 3 or 4 XML's I have modified sense resistor with 0.04 Ohm value. Output current on high increased up to 1.5A.
    For the price it has one of the best user interfaces in comparison with similar drivers
