I have owned the Fenix L2D for more than a year now. I almost never run it on turbo mode. The 100 lumen mode is plenty bright in pitch dark conditions. Is there any point to me getting more lights if I never even use the turbo mode on my fenix? I ride all on city roads, so most of the time the light is washed out by street lights. But in abscence of street lights, 100 lumen mode is very bright.
