Exposure Lights Zenith MK4 Bike Helmet Light with Mount, 2360 Lumens, Dark Grey

The Exposure Lights Zenith MK4 is a high-performance front light designed primarily for mounting on cycling helmets, though it also comes with a handlebar mount for versatile positioning. It serves as a powerful illumination tool for cyclists riding in low-light conditions or complete darkness, particularly off-road on trails where seeing the path ahead clearly is crucial for safety and navigation. The light projects a beam to illuminate the rider's immediate field of vision, which is especially useful when navigating technical terrain where handlebar-mounted lights might not follow the line of sight. The light's core feature is its output of 2360 lumens, achieved through modern LED and battery technology housed in a compact unit weighing just 150 grams. It employs a diffused 12-degree spot beam, designed to provide a balanced spread of light without excessive glare. Constructed from precision CNC-machined 6063 aluminium with a hard-anodised gunmetal grey finish, it is built for durability. It meets the IK09 rating for impact resistance and IP67 standards for dust and water ingress, making it suitable for use in all weather conditions. Charging is via a modern USB-C port, with a full recharge from empty taking under three hours, and it is compatible with most power banks for convenience on longer trips. This light is best suited for serious mountain bikers, gravel riders, and commuters who require reliable, high-output lighting for pre-dawn, evening, or night-time riding. The included helmet mount makes it ideal for technical trail riding where illuminating the exact direction you are looking is essential. Its robust construction and weatherproofing ensure it can handle the demands of regular use throughout the year. The package provides everything needed for immediate use, offering a practical and high-quality lighting solution for enhancing visibility and safety during nocturnal adventures.
