The Lezyne Helmet Fusion Drive 500+ is a helmet-mounted LED front light suited to riders who need high-output, weather-resistant visibility across varied riding conditions and disciplines. Producing up to 500 lumens with a maximum runtime of 35 hours, the light pairs a modern optical design with a CNC-machined aluminum body featuring integrated cooling fins - a construction approach that balances thermal management with durability in a compact form factor. The unit charges via a water-resistant USB-C port and carries an IPX7 waterproof rating, making it a reliable option for unpredictable weather. Mounting is handled through a GoPro-style helmet interface paired with a high-strength composite mount and non-slip padding; a versatile Velcro strap secures it to most helmet designs. The Helmet Fusion Drive 500+ is compatible with the Lezyne Infinite Light Power Pack XL+ for extended-range riding.Outputs up to 500 lumens with a maximum runtime of 35 hours on a 1400 mAh internal batteryCNC-machined aluminum body with integrated cooling fins handles heat dissipation during extended useIPX7-rated waterproof construction withstands full submersion testing conditionsGoPro-style mounting interface pairs with a high-strength composite mount and non-slip padding for a secure helmet fitVelcro strap secures to most helmet designs without tools or adaptersCharges via a water-resistant USB-C port; cable not includedCompatible with the Lezyne Infinite Light Power Pack XL+ for extended runtime capabilityItem SpecificationsBatteryUSBLumens Front500Recharge TypeUSBWeight136 Lezyne Helmet Fusion Drive 500+ Headlight Headlight, Rechargeable EAN: 4710582541261 MPN: 1-LED-38H-V137
