I rode with another rider that had your 350. Yeah, extremely bright. He had it angled slightly upward on the seat stay, and at 10 feet back from him, it was aimed directly into my dark sunglass covered eyes. Too bright to stay there! Aimed exactly horizontally, it should be reasonably okay for following riders.
I have the Hotshot 150.
The best daytime mode is the short, sharp single flash "Daylightning". It's visible at noon for a quarter mile up the road. And still has a very long run time, since I have it set to 2 flashes per second.
For evening group rides, the only non-annoying mode is the steady glow, dialed down to it's minimum brightness.
Run times from the box. 1 flash per second is 37 hours. Steady light at max is 2 hours.
