  • Cheap good 4x-6x 1W LED power supply

    posted by matutano6

    - Very cheap- Stable output- Good voltage: I meassured 7 units by my own between 21v and 24v. These voltage are very good for driving the voltage drop of 6 1W LED (sku 133086)- Good enough current regulation accurancy: suitable for 1W LED- The circuit PCB build seems to be of good quality
    I would like to test the power supply galvanic isolation from the AC line. A coil is present at the circuit, so its posibble the driver to be insolated, but I didn't test it yet. That feature of the power supply would be really nice!
    I was using 6 of these power supplies for more than a month for driving 6 1W LED (133086) each 10 hours a day and I'm really happy with the result.
  • Great power supply for the 1W led.

    I purchased this power supply for testing my 1-watt power LEDs. Works perfect! I also wanted to test the power supply itself to see how it performed. I connected a single 1-watt power LED with heatsync, (LED sku 13612), to the, Waterproof 350mA 1W Power Constant Current Source LED Driver, and left it on overnight. The LED was only slightly warm and the power supply itself was still cool to the touch. Also, there is no light flickering at all. The power supply produces a pure DC power. Very good power supply. Very satisfied!
    Overall, good power supply for any one watt LED. I have also used it with the, CYEE055YW080A 3W 80-Lumen 3000K White LED, (sku 13613), with excellent results.
    Bottom line, I recommend this power supply for its ease of use, compact size, and overall excellent performance. Well worth the money. Buy it!
  • Good Driver BUTTTTTT....

    I bought 5 at onceGood DriverWaterproof is always a plusThis driver is actually smaller than the 1W led 320ma driver which is a plusIt is a better colour than the one in the picture
    not impressed at all with broken parts manly due to bad packingWas impressed with delivery time though, I recieved it in about a week which was suprising since it usually always takes about 3 weeks to arrive
    Good driverGood Price could be a bit lower but at this time you will not find a cheaper waterproof oneIf all my drivers arrived in one piece i would give it 4-5 starsI gave a lower rating on usefullnes because it is less usefull without those screw holders
  • excellent source of current

    Excellent source of current. Provides constant current over a wide voltage range. I measured the range from 24V to 35V and the current was still exactly the same 320 mA. The source is pleasantly small, execution is precise. Insulated against water. When operating with a minimum of heat. I eat it with powering 10W 3200K LED module, function OK.
    Great little resource with a wide range of supply voltage. Ideal for LED applications from the 8 to 14 LEDs.
  • Does what it is expected to

    posted by Alshevts

    Working as it should. Quality is fine. Robust metal housing. Analogs at my local reseller are much more expensive. Nice and compact waterproof led power source. You can courageously mount it in bathroom, kitchen, outdoor, in the basement, garage and wherever there is a possibility of moisture penetration. What else should be said?
    Also it comes with nice 2-pin connector, which is not stated in the description
    A good choice if you need such a power source
