Today I have a review of my favorite EDC flashlight. It is the Streamlight PT 2L. The PT 2L is a small tactical flashlight weighing in at only 2.8 oz and 4.68 inches in length. For its small size it puts out an incredible 180 lumens. The PT 2L runs off of two CR123A Lithium batteries. It has three modes: Hi (180 Lumens for 2.5 hours) Low (50 lumens for 50 hours) and a strobe mode (up to 6 hours). It is waterproof to 1 meter for thirty minutes.
