3w led driver Customers Reviews

  • This driver is not 680mA

    posted by whorled

    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, not shown in picture.
    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. This 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 driver

    posted by Chemic

    Good quality driver. Aluminum case and waterproofed. Very safe and beautiful.
    Gives 0,3 A at 12V, so it even 3,6 W!
    I use it for 2 LED strip lamps SKU 33059. Its power is enough to give bright light. Another 3W drivers work with only one of them.
    It is more expensive than analogues in plastic cases, but it gives higher current, and more safety. Buy it if you need reliable driver for heavy conditions.
  • Godd pricing and performance

    * Very compcact * good build quality * easy to improve
    This driver is build on MC34063a base, so you can easily midfiy it, if you want to make dimminel light. All that you need to do, it's deolider 220 Ohm SMD resistor form the top of the board, and solider on ti's place in series 220 Ohm resistor and 5 KOhm potenciometr, and you get 3W led driver with variable current. But, if You ar intersted in usingi it on the lowest current you wil need to change Coil with bigger one, to prevent blinking
    Very good LED driverMust have for DIY projectVery cheap, about $1 per driver
  • Ceiling Lamp

    posted by megaseba

    Excellent finish all made of metal. very good lighting. The price and very convenient.
    The springs that hold the same roof are extremely durable and are very hard. I believe that the day will have to take her to end up making half of the ceiling below.
    Excellent product for the price advertised. I recommend buying it!
  • Good for replacement halogen lamps

    posted by Legora

    The lamps has a good quality, good design, easy installation, bright emitter, warm light, turns on and off instantly.
    Completed with Led Driver (AC 86~265V).
    I think that Led lamp is equivalent halogen lamp 20 watt
    I replaced five 20 watt halogen lamps, with these five Led lamps and haven't seen difference in light.
    I’ll buy led lamp more if this item will has long life.
    I bought five of these and put them in the kitchen. To my eye these products are better than the halogens.
    I recommend this Led lamps as replacement 20 watt halogen lamps.
