  • 100W LED driver module

    posted by Luc6580

    The power supply works perfectly wit the LED module 100W.It is very small:120 x 55x 35 mm.The power module delivers nearly no heat and makes no noise; so it has a good efficienty
    The use of the module is very good with the power LED module 100W; athough this module delivers a light that is to green to use in living surroundigs.To use it outdoor it will be perfectly.The eficienty of the led module is 80 lumen per watt; a good TL light delivers also 80 lumen per watt;when there will be an improvement, this kind of light will be used more in all kind of fixtures.Then there is still the cooling problem of the 100W module: you need a very big cooling sink or forced air, but that gives noises.
    The combination of the 2 modules (power driver and led module) is a great DIY project, but it is difficult to build it in a fixture by cooling problems of the LED module
  • 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.
  • 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.
    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.
  • good cheap led driver

    cheap, low heat, good quality of soldering, free space to solder additional resistor for more power.
    wold be nice to have IC connection diagramm for dimming. if any have more information about this driver please let me know.
    i made dimming by adding power MOSFET from computer mainbords CPU regulator so i can change otput power from 2w to 120w with potentiometer or through RC circut so having slow rise and fall of light.
    excellent driver for DIY applications
  • 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.
