The NU30 offers remarkable versatility with its three lighting outputs: Primary White Light, Reading Light, and Red Light. When using the primary white light, you can access up to three different brightness levels by short-pressing the power button, or activate the ultralow mode by double-pressing the power button. When the light is off, double-press the power button to access the reading light, providing two low-brightness modes. Alternatively, switch to the Red Light by long-pressing the mode button when the light is off. The red light protects your night vision or is used as a long-lasting signal light with three modes: Low, High, and Slow Flashing. The NU30 also features modes like SOS and Beacon to assist you in any emergency.
