The of the white output is 5,800 K with a CRI of 95, meaning colors appear natural—a boon for night‑time photography. 5.3 Infrared (IR) Performance When NVG‑Assist is enabled, the IR emitter produces a 850 nm beam visible only through night‑vision devices. Using a FLIR Scout TK, we measured a clear IR spot at 150 m with a 15 mW output (well within Class IIIa safety limits). The IR beam is coaxial with the white LED, ensuring that the NVG image aligns with the visible illumination. 5.4 Battery Life & Charging | Mode | Run Time (hours) | |------|------------------| | Low (10 %) | 12 h | | Medium (30 %) | In this article we will explore everything you
