  • Good, but lower power then indicated

    posted by ethgkk

    Relatively small, cheap equipment with an acceptable build quality.
    It has a noticeable delay, like 0.3 - 0.5 s when you switch it on due to the built in capacitor.
    I have built 4 lamps at home using these and 6-8 PCS of 1W Power Leds. So far everything is working as expected.
    Just have ordered the bigger brother: SKU 81770 for more power.
  • Dimmable 13~18 LED

    Hello allI drive to this review that I've found that a dimmable LED driver is not in the web shop is indicated as dimmable?It is item number 174475I compared it seemed to article number 171146Look at the pictures.
    I've tested this with the LED. DIY 7W 2800~3200K 560~630LM Round COB LED Module (DC 21~24V) With these 3 LEDs 7w (141851)These LEDs are beautiful in color temparature.
    I am probably going to bying more.
  • 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.
  • Its not 12V output it 24V

    posted by Hanina

    Low price, Build is OK, soft wiring, Small size easy to mount inside lemp or other unit, easy to wiring
    Can be nice if bottom PCB will be cover with protective plastic to avoid hazard from the 220V, I warp my device with adhesice plastic rebon isulator
    Spec is not correct the unit is 24 volot insted of 12 volt this cause LED it to heat up and eventualy blow.
  • Great for driving two 30W LEDS

    posted by rusty1964

    Easy to connect and use.Does not get too warm with generous heatsink fitted.
    This unit, plus two 30W warm white LEDs makes great room lighting, noticeably brighter than equivalent power of compact fluoros, and no two minute wait for the fluoros to reach full brightess. The turn on delay is disconcerting for a few days and then you get used to it and stop having a momentary thought that the lights have failed :-)
