    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week


    Small, very easy to use driver. Based on well-known PT4115 chip so it will be easy to change output current (up to 1.5A) or add dimming wire

    Works nice with 2 LEDs starting from 6.1VDC (with 5.55 V output)/ Can accept DC and AC - no problem with wrong polarity.

    Will be used for bike headlight.


    M16 legs too thick and solded on PCB surface.
    Broke one leg while inserting driver :(
    It would be better if the legs were soldered in metalized holes.

    DIM pin not wired.


    Good for this price.


    Great product for bike headlight.
    Plan to buy more for friends.
