User Review: Princeton Tec Quad

For overall usable light, the Quad does everything I want it to. Like all Princeton Tec lights, you can drop it, throw it, and just beat the crap out of it and it just refuses to break.

It is very consistent in the light power and gives you a nice warning when the battery is low (this is rare because they last forever) and still gives you enough light for the rest of your trek before it goes dim. It covers the width of the trail and goes out about 25 feet in front so you are covered.
