Featuring a large push button for easy control while wearing gloves and a strong, grippy "gator" clip, the 3C Gatorlite eLED Z1 Herculite Flashlight from Underwater Kinetics is ready for a full day's work. The electrically nonconductive light is resistant to many common industrial chemicals and rated IP67 dust and water resistant, submersible to 10 feet. Its Thermal Recovery System transfers heat from LED to warm batteries for better performance in cold weather, and a pressure equalization vent allows any gases that may leak from batteries to escape. Powered by three C batteries (separately available), the light emits up to 500 lumens in three brightness levels with a maximum runtime of 30 hours.
