Stay ready to spot the details. The G20 pen light features COAST’s legendary Inspection Beam, prized for its perfect circle of detail-revealing, anti-glare light. No wire, connection, or leak can hide. With a beam length of 21 meters (68 feet) and run time of 11 hours, this single-mode sidekick features a steel pocket clip and weighs less than 3 ounces for easy carry—and it comes in five color options: black, red, blue, green, and orange.
