Bruce of BB2K Airsoft does love reviewing flashlights, weaponlights, and taclights with the latest being the feature-loaded Nitecore SRT9 Flashlight... "I just have to show you the Nitecore SRT9 flashlight. Equipped with the Smart-Ring-Tactical, the Flashlight allows you to quickly access all light modes and adjust the brightness continuously from 0.1 to 2150 lumens. As a Multi-LED Searchlight it offers not only normal light but also UV-light for the detection of fluorescent objects; red light for inconspicuous night vision without affecting eyes (change light/dark); green light offers the best way to read in the dark eye-catching and inconspicuous maps etc.; and BLUE light offers similar function as UV used for blood tracking (hunters/police). The special functions Strobe, Beacon and warning light (red/blue flashing) round off the whole optimally."
