With four colors to choose from, the TX10 flashlight has its own distinct skill set. In addition to a 73 lumen white light, the TX10 has a red, blue, and green lights. Red is best when you only need a little bit of light - it preserves night vision. Green preserves night vision but with adequate color distinction, which allows hunters to move about at night or read maps without scaring off game. The blue preserves night vision and can cut through fog. A lightweight aluminum casing offers great durability and will hold up to heavy daily use. Backed by Coast's lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards by an independent laboratory.
