No such thing as too much power, just badly pointed power!
I agree its better to be moaned at than mown down.
I use a Troute liberator, on full but aim it down 5 degrees. The spread is good and similar to a cars dipped beam.
I then have a Hope vision 2 on my helmet, on full and slightly dipped, but ready to be used tactically to make sure drivers have seen me.
I use both on steady beam when dark and have separate flashing LEDS for getting the “i am a cyclist not a slow motorbike” thing.
