  • Very nice driver

    posted by FredericoRamos

    Great driver. Best of all I bought here in Deal Extreme. Steady 950mA readings. Do not become very hot, just warm.
    I use to drive 10 x 3W cree leds or 3 x 10W superleds. In both case the driver works perfectly and no overheat.
    Just buy it. With the shipping cost included, it is the best deal you will find out in the net. Just bought 5 or 6 I gess.
  • serves to what was done

    Answers to what was done, no heat, no noise and good weld quality.
    just a tip for a joint purchasing, using 10 LEDs of 1W following link:
    http://www.dealextreme.com/p/1w-80-90lm-warm-white-led-light-bulbs-3-2-3-4v-10-piece-pack-80086
    I use three sets of three parallel
    I believe it has a better cost benefit with this set suggested, and that is better than buying the driver with cash. More worthwhile.
  • Meets with it specified.

    It works really well, delivering exactly the specified 3.0A. It looks well built, has a heat dicipador acquiring low temperature. Still do not know if dimable, but I'll find out soon.
    These will be used together with a 100W LED to illuminate my backyard, you save enough energy compared with incandescent technology obsolete.!!Sorry for my English, it is translated by Google.

  • Works reliabily

    I have a few of these to power different 40 watt blue LEDs. They work reliably with no heat issues. They are forgiving if you ever cross wires and make a spark. Mine have worked for days continuously.
    Could be a bit cheaper, but I don't know of a source for cheaper ones, so if you need 40 watts then you have to pay the price.
    Does what it's supposed to do.
  • This driver is not 680mA

    posted by whorled

    It is relatively inexpensive.It is small and light.It is waterproof.The wiring not too thin.It comes with a connector on the dc side, not shown in picture.
    The DX listing for this product shows "Waterproof 680mA 3W Power Constant Current Source LED Driver ". The label on the driver has no output current shown, only "Output 1x3w"
    Came here expecting this driver to be suitable for power testing single 3w leds at 680mA. This driver only delivered 540mA into a single 3w led. It was tested with several different single leds; 2.5v red 660nm 3w leds, 3.5v blue 450nm 3w leds, and 3.7v warm white 3w leds. Multimeter showed each one receiving only 540mA. Left disappointed.
