Proton is Single AA Cell, Multi LED, Microcontroller (µC) Controlled and Regulated Light with Six 5mm 2X Bright White Nichia CS (C0 bin) LED's arranged in Hexagonal manner and One 5mm Red LED in center. Body is built of Aluminium, with Type III Hard Anodizing. Proton Comes with a Belt Clip and Key chain attachment, loaded with Lithium 1.5v Battery. UI(user Interface) is Simple to operate and If you own a Freedom Max or X Light from Photon Light LRI then it would not be difficult to operate the light.

Product Update: The New LRI Proton Pro is now available check for LRI Proton Pro Review Click Here. The multi-LED array will be replaced by a single Cree XR-E LED and a PMMA (polymethylmethacrylate) lens. Red LED for night vision protection will also be there.
