  • Good quality, 7.4W output, 8.6 watt consumption

    posted by nagymate

    Small, good quality. High frequency output (LEDs will not flicker). Protected against too small resistance loading.Large input voltage range.
    While output power is around 7.4 Watts, consumption is 8.6 Watts (from 230V input voltage). This means 86% efficiency. Output voltage is vary depending on the loading to achieve almost constant current. In case of open circuit the output voltage is around 45 Volts.
    If You only need only 7.4 Watts and 86% efficiency, this product can be a good choice for You. You cannot use 10W 12V LED chips with this, because the lowest output voltage is higher than 12V
  • This driver is not 680mA

    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, 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.
  • I dont know

    It works. The electronic is selaed.german:es funktioniert. Elektronik ist vergossen.
    I dont know, if there is an EMI-filter was inserted. I think, it's protected for use in wet rooms. In one of all supplies the sealing-material was to little, i can see some electronic components. Price is ok.german:Ich weiß nicht, ob ein Entstörfilter eingebaut wurde. Bei einer der Stromquellen war die Füllhöhe so gering, dass man Umrisse elektronischer Bauteile erahnen konnte, aber doch vollständig bedeckt. Ich denke, dass es mindestens IP44 wasserdicht ist.
    Text partly translated with a programm. Sorry for my bad english. I am german.
  • Quality 10W LED driver

    posted by damyano

    I`m very satisfied with the quality of this product ! Really it is water protected, and it can be installed in the cover of the aquarium, I`m using it to rune one of these leds: SKU: 152367. Heat, but not much. Really fast shipping. It is wired, and has a label, so it is impossible to go wrong with the connection. The wires are not thin, and are plated, which is very comfortable for
    Worth it`s money, and i will order much of them for my aquarium lighting.
    Cheap, quality and reliable LED driver. I`m satisfied.
