The NU40 uses a rotary-style control arrangement to make brightness selection accessible on the body. Primary white light provides the main illumination, with auxiliary lighting options for other low-light tasks around camp or a work area.
Its rechargeable battery is integrated and served by USB-C. The adjustable headband mount lets the beam be aimed without repositioning the entire headband. This is the NU40 configuration, with the exact source, power and output information listed below rather than borrowed from another NU-series model.
