The versatile P7R Core torch offers exceptional power and forward-thinking technologies like the Smart Light Technology for custom light functions. The lamp is powered by a 21700 Lithium-ion battery, which can be easily changed by opening the end cap. Thanks to our Flex Sealing Technology, the P7R Core is protected against dust and water, and can even handle permanent submersion.
