Knog Blinder Arc 1.7 Front

This is the first light we’ve tested from Knog. It’s more of a budget light at $65, putting out 184 Lumens. These lights were designed with quality and style. This light is quite small and it has the look and feel of a quality product, as rubber and metal are molded together to create a very slick device. A metal front for heat dissipation is integrated with a rubberized back for good grip and ergonomics.

The USB charging port for example, is a small plug that folds out of the light. This makes it very convenient for plugging into a laptop, as no wires are needed. When plugging into a USB adapter, an optional wire is included in case there are space issues near the plug. The integrated USB plug was designed by Knog to withstand moisture.

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 »
