    posted by johnyconny

    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.

    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 LED driver (power supply) is built very well. It is water resistant and designed to use with outdoor LED lightning. Dimensions are quite small. Recommended to everyone.

  • Good quality, 7.4W output, 8.6 watt consumption

    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

    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.
