Calculated at Checkout

Stay ready to spot the details.

The G20 penlight 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.

Built from top-grade aluminum for durability over the long run, the G20 penlight is IP54 stormproof and dust resistant, primed for the job. Built with COAST Alkaline-Dual Power technology, the G20 penlight is powered by 2 x AAA alkaline batteries and can also operate using a COAST ZITHION-X™ rechargeable battery (sold separately) for added convenience and cost savings.  

With Coast’s commitment to quality, the G20 Flashlight is impact resistant, weather-resistant and its LED is virtually unbreakable. The G20 Flashlight is backed by Coast’s lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards.



Never miss a detail. The Inspection Beam cuts clean, consistent light from edge to edge to evenly illuminate work spaces. Engineered for pen lights that fit in the pocket, this beam simplifies up-close work and brightens hard-to-reach objects.


The same light every time. Keeping it simple with COAST single-mode lighting means you can rely on an even, bright white beam every time.


Don’t worry about the weather. COAST lights that have passed the IP54-level resistance tests are splash-resistant and built with durable materials that stand up to nature.
