KIJI 3 almost certainly refers to the B.E. Meyers KIJI K1-3°, a 3‑degree VCSEL-based IR laser illuminator head that fits 300‑series Scout-style bodies (CR123).
Class 3R VCSEL infrared illuminator (no aiming laser), using similar tech to the MAWL-DA but in a single-head, modular form factor.
K1-3° version is the “tight beam / long range” model; there is also a K1‑10° flood model.
Max output: up to 150 mW IR, 850 nm wavelength.
Power levels: 4 programmable PLs, typically 5 mW, 15 mW, 85 mW, 150 mW.
Battery: 1x CR123A; runtime about 4 h 15 min at full power constant-on before noticeable ramp, plus ~30 min down to 10% output.
Range: rated 400 m+ with the 3° beam for clip-on or mid/long gun use.
Weight: ~3.1 oz with battery, 2.5 oz head-only; 300‑series footprint.
