  • Not bad driver

    posted by komik777

    I received the 4 pieces: 2 marked “JR Drive”, and 2 marked “QiaoDuoTianCong”.
    The JR Drive is very good quality, made very accurately, very good work.
    The output current doesn't achieve the value it was supposed to. I have measured all the 3 devices and the current was 1.23 A for all of them and not 1.4 A as announced. Output voltage: DC 23V.
    The "JR Drive" is good product, good price, I recommend.
  • Its not 12V output it 24V

    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.
  • Good quality driver

    Seems to be well-built and sturdy. Has leads already attached to connect to the LED.
    You have to solder your own leads at the AC end, though it is clearly marked. It is also a bit larger than I was expecting, so make sure to check the measurements before ordering, if you're planning to use it in a smaller space.
    Seems like a good product. Time will tell whether it lasts, but from its appearance and performance so far, I'm optimistic. Planning to order at least one more.
  • Product is as shown, good quality.

    Item works fine and provide the same quality of output to my former 12W LED downlight.Highly recommended for those who's looking for a replacement for the 12W driver spoilt like mine did.
    The first few days of using it is a little weird.Maybe I forgot how my former driver works but this one has a glowing effect during switching it on and off.You'll see the LED fade in and fade out (when switching off).And in a really dark room like mine, you can still look at the LEDs have a little glow left after turning it off.This isn't at all a cons point though.Finger crossed, hope this last longer than the last one.
    Recommended, a reasonable replacement for my broken driver. Plus the shipping is free and the packaging is good.
  • 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!
