Lumen 400Z 3.0 Waist Light

Precision and versatility shouldn't weigh you down. The UltraSpire Lumen 400Z 3.0 is the agile cousin to the high-output Solstice, designed for runners who need a lightweight, customizable beam for technical night efforts. This 3.0 version features a specialized zoom function, allowing you to toggle between a wide-angle flood for peripheral awareness on open paths and a focused spot for piercing through the dense fog and technical turns of a maritime forest. By casting light from the waist, it preserves the 3D depth perception that headlamps lose, while the new "Race Fit" buckle and limited-stretch conical belt ensure a fatigue-free, natural breathing pattern even when you’re pushing a high-intensity pace.

• 3D Lighting Technology: By positioning the light source at the waist, this light casts shadows over rocks and roots, giving you a clear, three-dimensional understanding of the terrain ahead.
• Adjustable Zoom Beam: Features 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: Now upgraded with a USB Type-C port for significantly quicker charging of the included 18650 battery, complete with a tri-color power indicator.
• 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.
