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.
