no matter what i tried the A pin on this only ever outputs 800mA and doesn't seem to change no matter what settings, what brightness, and how long i'm nowhere near it and try to activate it, so i'm guessing it's just broken. pity there's no documentation online on how these work
well nevermind, the diode really should've been a clue. A is actually voltage input and L is the load output 0-2.5V. it still works
