2015 Lights Shootout

Princeton Tec is an outdoor sports company with a loyal following. The Princeton Tec Push is a well-built, basic light for commuting, but it hasn't changed much in two years and that is a bad omen for an LED light.

Its biggest flaw is that it's not rechargeable. Bearable a couple years ago, it's simply not competitive with a crop of $50 lights that have developed equal or better brightness.

For $50, Princeton Tec offers a light that claims 150 Lumens, but actually measured higher at 199 Lumens. It also sports great side lighting with a nice red strip of light on each side.

Beam Pattern Photo

We photographed the lights in the same location setting with the same camera settings. The photos were taken in the back yard that is approximately 25 yards long. These photos feature many objects and a distinct background to analyze detail and beam pattern. Compare all Beam Patterns here »
