Lumen 400z

The Ultraspire Lumen Waistlight redefines night running visibility. By placing the light at waist level, it casts natural shadows across uneven surfaces—giving you a clearer sense of dips, rocks, and roots before you step on them. This shadow depth perception advantage is something headlamps can’t match, letting you react faster and run with more confidence in the dark.

Its wide, even beam pattern eliminates tunnel vision and hotspots, while adjustable brightness ensures optimal visibility without blinding oncoming runners. The lightweight, ergonomic belt design stays stable over any terrain, keeping your hands free and your stride unimpeded. Built for endurance, the Lumen is perfect for trail runs, ultramarathons, and fast-paced night hikes.
