LRI: Photon Proton

Photon Proton is the one of the most advanced light in its class. The light is manufactured by Laughing Rabbit Inc. (www.laughingrabbitinc.com) the original manufacturer of Photon Light and Photon Proton. 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. The Microcontroller (µC) UI remains the same. With the new Cree XR-E LED Proton Pro will provide 2 to 3 times the light output of the original Proton reviewed here. The light is expected to be available early next year. Visit Laughing Rabbit Inc. (www.laughingrabbitinc.com) web site for the official announcement.

Light Features:

• Runs on Common AA Cell
• Red & White Beams
• Both beams are FULLY Dimmable
• UI(User Interface), best in it's class, Similar to Photon Freedom Max
• Nichia NSPW500CS C0 LED
• Soft Starts (about 1/2 second)

Light Operation:

• Single Click to Turn ON with White LED's on Full Power, Single Click to Turn OFF the light. Once Off, Red LED Flashes once
• Once Light is on in Full Power, Press & Hold to decrease the brightness. You can release at any time and then again press and hold to keep decreasing. Once at Minimum, it will flash a couple of times in minimum to confirm that min. has reached. from there on if you again press and hold, it will change mode to Slow flashing, Fast Flashing, SOS, Beacon Locator Flash etc modes
• Press & Hold to Turn ON Red LED with minimum brightness, Keep holding for Increasing Brightness to Full power
• Once the light is in Full Power RED, pressing and holding will change modes same as mentioned above
