It's the Olight HS2 Headlamp this time for this latest review by Airsoft & Milsim  News Blog (AMNB)... "This is a headlamp especially designed for fast-paced activities. That means fewer brightness modes, no strobe and no 'moonlight' mode. With a 50 lumen minimum output on flood mode low, it might prove to be a bit much for reading a book in your bed and definitely too much for sneaking around the house.
