Pelican M1 LED 2310 Flashlight is an excellent pocket light. Pelican M1 2310 LED Flash Light uses a 1 watt Luxeon module that's extremely bright and efficient. The compact CNC-machined aluminum body with knurled pattern (for a secure grip) is resistant to extreme temperatures. And the tactile response click tail switch of the Pelican Flashlight turns it on for constant light or momentary blink. The M1 2310 LED Black Flashlight by Pelican comes with a free Cordura holster with back-up battery pouch and 1 CR123 lithium cell.
