Princeton Tec Tec-1 Flashlight

It couldn't be easier to pack and carry, but the Tec-1 Flashlight from Princeton Tec performs like a bigger light, with a bright 250-lumen spot beam controlled by a two-stage push-button tailcap switch. The Tec-1's polymer-coated metal housing has a diameter of 1", so it fits many common adapters. It is IPX7-rated for water resistance and submersible to 3.3' for up to 30 minutes. Powered by one CR123 battery, it has a total runtime of 1.3 hours.
