Throw those penlights away! This little powerhouse delivers a surprising BLAST of light given its compact size. You will want to pick up several for key rings, backpacks, briefcases and vehicle glove boxes. The convenient built-in clip allows you to attach it to your hat for hands free illumination or clip it to your belt or backpack for convenient placement. The Princeton BLAST Flashlight is one of the most versatile products in the Princeton Tec Flashlight line, and like all Princeton Tec products it's made in the USA and maintains waterproof integrity to 1,000 feet.
