Some data Lezyne provides about the light.
Blast (1000 Lumen): 2:10 h
Enduro (600 Lumen): 3:30 h
Economy (250 Lumen): 9:00 h
For my purpose it misses a mode in between Enduro and Economy. Also the beam"pattern" seems to send to much light into the air, which would be great for trails (as it is with so many powerful lights out there), but is lost light and energy out on tarmac roads.
I've got the 1500XXL - Economy mode is surprisingly good - I commute in pitch black with it daily. Beam pattern is wide but decent, doesn't throw too much away. You're right that for racing you'd likely want something in the middle though.
