power led driver constant current Customers Reviews

  • Cheap and good

    posted by matutano6

    - Cheap- Rates 310 to 330ma, good for 1W LED- Works just right from 4 to 6 1W LED pieces: 21v to 24v at open circuit, enough for 6x white 1W LED voltage drop.- Electronics looks good at simple sight
    I used 6 of them to build 6 LED lamps with 6 1W LED each. At the moment, they are working very well.Because they are current regulated power supples, the LED must be arranged in series; this is not a con because LED must be driven by current regulation.
    In my country, I cannot get such a driver for that price, taking in mind that the unit works well.
  • Works great - hardly any heat dissipation

    posted by debra

    Great little constant power sources. Its tiny and has almost no heat dissipation.
    It's a pity there is no 3x3 watt equivalent available. I used it to drive 2 3 watt emitters, and that works great.
    A tiny device that allows you to drive 2 to 3 1 or 3 watt led emitters. Works great, low price, a pity there is no 3 x 3 watt version..
  • 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.
    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. The 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.
  • Great for DIY lights

    Its sealed so no need to worry about electrocuting yourself on components at mains voltages. Mounting lugs to attach it to your housing.
    I used two of these to under drive twenty 3 watt LEDs in a florescent light housing.It would be nice to have 20w drivers that can drive four 5 watt LEDs or two 10 watt LEDs, so I had less soldering to do.
    Great easy to use driver for twenty 1 watt LEDs (10S2P) or to under drive ten 3 watt LEDs.
  • 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.
