Delivering up to 400 lumens of illumination, the Illumi offers High, Medium, Low, Strobe, and Turbo modes, giving you flexibility whether you’re navigating technical terrain or powering through late-night training miles. A built-in sensor mode allows for hands-free activation and cycles through all standard brightness levels with a simple wave, perfect when gloves, mud, weather, or fatigue make button access difficult. Designed with an adjustable spot-to-flood beam, the Illumi lets you fine-tune your field of view, from a precise focal point to a wide flood pattern, making it adaptable to any trail, pace, or environment. The durable aircraft-grade aluminum housing helps dissipate heat efficiently, ensures long-term durability, and weighs just 25g without the battery (42g with) and features a soft headband that provides a secure and comfortable fit over long efforts. A rechargeable 14500 battery powers the system and pairs with USB Type-C charging for quick and convenient power access. Depending on mode, battery runtime ranges from 4–10 hours and also includes a battery indicator light that when toggled on quickly illuminates green, gold, or red indicating battery level. The Lumen 400 Illumi balances minimal weight with dependable output, making it the ideal choice for runners and adventurers looking for a compact yet capable lighting system and pairs perfectly with any UltrAspire waist lights.
