  • 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.
  • Good driver

    Good quality driver. Aluminum case and waterproofed. Very safe and beautiful.
    Gives 0,3 A at 12V, so it even 3,6 W!
    I use it for 2 LED strip lamps SKU 33059. Its power is enough to give bright light. Another 3W drivers work with only one of them.
    It is more expensive than analogues in plastic cases, but it gives higher current, and more safety. Buy it if you need reliable driver for heavy conditions.
  • Does what it is expected to

    Working as it should. Quality is fine. Robust metal housing. Analogs at my local reseller are much more expensive. Nice and compact waterproof led power source. You can courageously mount it in bathroom, kitchen, outdoor, in the basement, garage and wherever there is a possibility of moisture penetration. What else should be said?
    Also it comes with nice 2-pin connector, which is not stated in the description
    A good choice if you need such a power source
  • A good driver for LED 3W

    posted by evgenic

    I bought this driver for 3W Osram LEDs (SKU194296). With this driver - good brightness LEDs, although it is not the limit, because the LED's operating voltage of 3.9 V and operating current of 750 mA. The driver outputs a voltage 3.63 V and current 650mA. Thus the total power is obtained understated ... But I tried to connect the LED Cree Q3.Operating current 700mA turned to him and he shines much brighter (a feature of the LED Q3). The advantages of this driver could be considered that it is made in the closed case and sufficiently thick wire.
    I would recommend using this driver with LED Q3.Power same but higher brightness.
    All in all - a good driver for LED 3W (2.5W ~ real power is ~2.5W , but the LED is less heated). I found this driver only on the DX (for the presence of rare items - I love DX). I recommend to buy!
