  • Good LED Driver but little bit too expensive

    posted by logologo

    Very easy to use. no problems so far.it works with less than 30V.Input: 105mA 234V = 24,57WOutput: 1,016A const. 23,62V =24Wefficiency: 97,67%temperature after 2h: 36°C
    a little bit to expensive. it could be 3$ cheaper.it do not work with 12V output.tested with 2x CREE MK-R LED.please make shure your driver is cooled down when you use it. do not overheat and it will work perfektly.
    all over. a good LED Driver. i will buy it twice or more if my LED works as i want it to work ;-)
  • Good quality

    - Has enough isolation between AC and DC sides.- Heat sink is isolated (connected only to some noise filtering capacitor) so you can ground it.- Input has common-mode filter and fuse.- Output current is 1A exactly.
    Put it in a grounded metal box and you have a very safe power supply. The metal box will make sure that it won't catch fire.
    Works fine with SKU #95820.
  • very good driver

    posted by LeatherfaceNL

    its a very good LED driver.
    bought 3 but only needed 2 but later had to replace an older one that died (other brand and quality and more expensive)
    these run longer than the original expensive ones.
    and its even running 32 x 1w powerleds.
    it was a lil gamble because it says 21-30 leds but seems to work out perfect.
    its easy to install and connect.no extra work needed.
    shes running nice n smooth already a long time.
    its not running hot,the 32 leds burn just as bright as the 30 on the other one(at least i dont see the diffrence)
    one word GOOD stuff
    wish i bought more because all my original expensve ones are dieing.
    i need another one like this.
    great driver! if your planning to power up some 1w/300-350mA powerleds.(in between 21-30 ofcourse).. its a must have
  • Good product for a nice price

    Very easy to wire, seems to not produce parasites.Protected against reverse polarity and surge.
    I installed 2potentiometer instead of one as someone proposed.The first potentiometer is a 4.7Kohms and the second a 500ohms. This way i can dim correctly the LED, with only a 4.7Kohms i couldn't do it correctly.You will need AT LEAST one potentiometer of 4.7Kohms or else you will never get a strong light.
    It doesn't get hot after using it few hours.I set everything in a plastic junction box.
