  • 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.
  • 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
  • very good driver

    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
  • Great for driving two 30W LEDS

    posted by rusty1964

    Easy to connect and use.Does not get too warm with generous heatsink fitted.
    This unit, plus two 30W warm white LEDs makes great room lighting, noticeably brighter than equivalent power of compact fluoros, and no two minute wait for the fluoros to reach full brightess. The turn on delay is disconcerting for a few days and then you get used to it and stop having a momentary thought that the lights have failed :-)
  • OK

    Able to limit current unlike most of other cheap voltage converters;Indicator showing if current cap is being hitted;
    Good combo with http://www.dx.com/p/0-28-led-red-dual-display-3-digital-current-voltage-meter-ampere-voltage-meter-black-10a-238365
    Nice product for charging batteries or experimenting with things without worrying of short circuit.Now charging a lamp using this without even removing batteris from it. Even if I accidently turn on the lamp, it won't immediately burn LEDs due to current limit.
