The HIKMICRO HM-L128IR is a dedicated 850nm infrared illuminator built to extend the working range of a HIKMICRO Alpex digital day/night riflescope, feeding it extra IR light so target detail stays clear well beyond the point where ambient or moonlight runs out. Running independently of the scope's own IR output, it delivers up to 700mW with an adjustable 6° to 35° beam angle, so you can switch between a tight spot for distant ground and a wide flood for close cover work, with a stated illumination range of up to 200m. The metal body is rated -20°C to 50°C for genuine UK field use, weighs 150g without battery, and measures a compact 151.11 x 38.2mm so it sits low alongside the scope body. Power comes from a HIKMICRO HM-3632DC or HM-3633DC 3350mAh battery pack, giving up to 5.5 hours of runtime between charges. This listing is for the illuminator only — it does not include a mounting bracket, battery or charger, so check you have the correct HIKMICRO Alpex bracket before ordering.
