3000lm, 12000cd is floody. it is not a bike light but i suppose you could use it as such if you found a mounting bracket. you will blind everyone nearby with a floody beam.
i recommend you get a bike light since the reflector is designed to have a beam pattern and cutoff, like car headlights. it usually comes with a bike mount also. most of the name brands have bike lights and there are tons of unknown brands also.
personally, i like the designs by fenix and niterider
