Use the JOBY GorillaTorch Switchback as a headlamp or a lantern--it's your choice. As a headlamp, the Switchback offers your three choices of LED light modes, and as a lantern this light is powerful enough to offer 360-degree illumination inside a medium-sized tent. Just pop the headlamp into the lantern case and pop the lantern lens up and out of its self-storage case.
The Gorillatorch Switchback transforms from a powerful, compact lantern to a high-performance head-lamp - using a single LED light engine - to become the perfect multi-functional light for the outdoor enthusiast. Hit the trail with the headlamp when you need solo lighting, then fold into the lantern housing to illuminate a social campsite setting.
