UltraSpire | Lumen 400Z 3.0 (Adjustable Zoom Waist Light)

Adaptable, 3D Illumination for Technical Night Efforts

Precision and versatility shouldn't weigh you down. The UltraSpire Lumen 400Z 3.0 is designed for runners who need a lightweight, customizable beam for technical night efforts. By casting light from your waist rather than your head, this light casts long shadows over rocks and roots, preserving the critical 3D depth perception that traditional headlamps tend to wash out.

This 3.0 version features a specialized zoom function, allowing you to seamlessly toggle between a wide-angle flood for peripheral awareness on open paths and a focused spot for piercing through dense fog and technical turns. Anchored by the new "Race Fit" buckle and a limited-stretch conical belt, it stays perfectly secure on your hips without bouncing, allowing for a fatigue-free, natural breathing pattern even when you’re pushing a high-intensity pace.

Key Features

• 3D Lighting Technology: Positions the light at your center of gravity to cast shadows over obstacles, providing a clear, three-dimensional understanding of the terrain ahead.
• Adjustable Zoom Beam: A versatile lamp head that tilts up and down and zooms from a wide flood to a concentrated spot, letting you tailor your light to the speed of the trail.
• Race Fit & Conical Belt: Engineered with a fatigue-free buckle system and limited-stretch elastic that follows the natural shape of your waist, allowing for unrestricted breathing and zero bounce.
• Fast USB-C Charging: Upgraded with a modern USB Type-C port for significantly quicker charging of the included 18650 battery, complete with a tri-color power indicator to track battery life.
• Aircraft-Grade Durability: Built from high-durability aluminum with an IPX7 waterproof rating, ensuring it can handle a total soak in a trailside bog or a heavy Atlantic downpour.
