dc led driver Customers Reviews

  • Good buy

    posted by Obnovec

    All included in the package, just mount it. Good quality power source. I have it almost 1year, it lights cca. 7h per day and it still functions without fault. Very good glue tape on the bottom of the LED strip, it sticks very hard.
    You can cut the strip and solder wires every 3 LEDs. The power source is a switching type. You can use it also for other things, just dont overload it (it can give max. 2A current)
    Nice for decorations. I have used it for illuminating a notice-board that is behind glass. It looks perfect.
  • Powerful driver

    Powerful driver,Good selection of modes.
    I have installed this in to a custom built torch.The torch setup has a xml-U2 led driven by this driver and fed from an ultrafire red 2600mah 18650.All test results taken in high mode.Testing the output from the 18650 gives 4.00V and 4.00A giving a total battery draw of 16WTesting at the led gives 3.10V and 3.50A giving a led consumption of 10.85WCalculating these figures in to efficiency shows that 32% of the power is lost within the driver.This driver, but with selectable mode blocks (3mode 5mode 8mode etc) would be greatMust be fed from a good cell, when fed from a 14500 the max current is 2A not 4A.
    This XML-U2 build is really bright,I can live with the lack of mode memory and the extra disco modes.GOOD DRIVER!

    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

    posted by Bezpieka

    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.
  • A cheap fix for your torch

    Used one of these to mend my AKOray K-106Easy to fit. I spent longer waiting for the soldering iron to heat up than fitting it.The three modes are Bright, Dim and Flash. After solving the problem listed below I am happy.
    Fitted perfectly into the torch.
