Questions, answered
How bright for technical trails?
Plan on 300-plus sustained lumens for rocky descents at speed. Burst modes help on route-finding sections but cannot be your whole plan.
How do I stop headlamp bounce?
Choose balanced rear-battery designs or a top strap, snug the band above the ears, and consider wearing the lamp over a thin cap to kill slip.
Waist light or headlamp for running?
Many ultra runners pair both: waist lights show trail texture and shadows better, headlamps follow your gaze. For one light, the headlamp remains the versatile default.
What runtime should I plan for a night ultra?
Your full expected dark duration plus 50 percent margin, at your main mode, not the box's eco figure. Pass-through charging or a spare lamp covers the gap.
