Delivery time is additional. Business days exclude weekends and holidays. Shipping details.A lightweight white-and-red headlamp in distinct colour editions
The NU21 combines primary white lighting with a separate red channel in a small rechargeable body. Dual-button operation and an adjustable mount keep its normal lighting choices available without a complicated control arrangement.
The light headband uses an elastic-cord format to reduce carrying bulk. USB-C charging serves the integrated battery, and transport lockout helps manage the controls in a bag. The selected body colour below is a physical edition of the NU21, not a different lighting specification.
Exact edition and supplied equipment
The rechargeable battery is integrated into the light. Headband and bracket are included.
