Not the Slowest

Hey Folks,
I have read the threads, all 2000 listing the great virtues of the Fenix L2D Premium lights and the Dinnotte 200L.

I live in NYC and commute in the evening or early am, and the streets are pretty well lit so I can see "almost" everything I need to.

What I need help with is:
a) Is the Fenix L2D Premium really a good light to illuminate a dark Suburban Street. It seems that to get the 175 Lumens, you would use Strobe mode. Isn't that a Flashing light?

b) Does the Dinnotte on Steady High beam give light to illuminate a dark Suburban Street?

c) With either light am I just getting a "Be Seen " light or a "Light up my Path"
light.

thanks in advance
