as a relatively experienced night time road rider-commuter, i truly believe that 300 lumens -like you said your light sheds- is output enough to safely speed at 40mph.
My current light setup is approx 250 lum, medium side spill and does the job fine at that speed. Considering that aging makes night vision worse -i'm 43 and already feel like sometimes my car's headbeam is weak - a younger person should be more than happy with your light output.
