The iRay / InfiRay AC70 BOLT Infrared Illuminator (IRAY-AC70) is a purpose-built, high-output near-IR lighting accessory for the BOLT digital night optics family. Emitting around 850 nm, the AC70 extends detection and recognition ranges in total darkness and low-light situations — retailers list effective illumination out to roughly 200 meters depending on the sensor and conditions. Compact and battery powered (18650), the AC70 mounts directly to BOLT-series optics or standard rail mounts, giving hunters and night-ops users a plug-and-play IR boost for increased target contrast without visible light. Follow the BOLT manual for safe operation and to tune output to your device.
