RECOMMENDATIONS BY OUR PRODUCT MANAGER, STÉPHANE
"As a user of the headlamp myself, I can say that the 100-lumens mode, which is already very powerful, is more than sufficient at night.And overall, a long-distance trail run involves 70% walking, therefore the 900 lumens only needs to be activated for reassurance during more technical downhills. Also, I recommend wearing the ON TRAIL 900 headlamp over a headband or cap for more comfort and support in case of heavy sweating."
