  • 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
  • CAN YOU SAY FAST SHIPING

    LET ME JUST RITE A FEW WORDS BEFORE I GET TO THE DRIVER.I HAVE BEEN SHOPPING WITH DEAL EXTREME FOR A GOOD TIME NOW AND THEY HAVE BY FAR THE BEST AND FASTEST SHIPPING FROM ASIA IM IN CALIFORNIA AND IT ONLY TOOK FROM THE DAY THAT I ORDERED

    IM USING THIS SST-50 DRIVER ON A CREE XML AND IT POWERS IT JUST FINE IT DOES HAVE MEMORY AND THATS FINE WITH ME ALL IN ALL IT EXCEEDS MY STANDERS.AND YEA IT DOES PUT OUT THE RATED SPECS OF 4.AMPS!
    VARY WELL MADE DRIVER GOOD PRICE VARY VARY POWERFUL.IM GOING TO BE ORDERING MORE OF THESE NEXT WEEK SO TAKE IT FROM A TACTICAL PRO. BUY SOME.
  • 70% Efficiency buck Driver

    posted by amelyman

    27,9 Watts power from source at High mode
    So, looks exactly for SST-90 LED...
    Probably I hame made some mistake thru measuring and the Efficiency is higher...
    I measured with UNIT UT-70A Multimeter the linear voltage and linear current. As I know, it is not exactly correct (LED power is not "Linear")
    Really powerful driver. So, it has 5 modes - 28 watts, 14 watts, 8 watts from the Source and fast strobe and S.O.S. modes.
  • 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
  • Good driver

    posted by kevmeister

    The driver is cheap and easily convertable to single mode. Output is good for my divelight project.Its small and fits my lighthead(26mm) perfect.Input voltage range is wide.Overall good driver.
    It would be nice if the wires to led are already soldered on and the driver is shrinkwrapped.
    Really nice driver for the money. I ordered 2 more for my next projects.
