I have a Nite Rider Lumina 700, and I tend to think its flash mode is a bit too bright. I am always conscious of using it and tend to point my light down further when I use flash mode. I wish there was different modes of flash, just like for steady. I have wondered if comparable lights from other manufactures also have such a bright flash mode, or if it a Nite rider thing. It literally makes road signs, license plates, and anything remotely reflective around you flash bright.

I do think a reasonably powerful light for commuting at night is good, depending on what your commute is like. Half of my commute I have my light in low mode, but there are parts where I definitely appreciate the hi mode as they are not lit at all.
