Optimal Heat Conduction*
Each time you turn on your flashlight, heat with up to 85 degrees is created inside the LED Power-Chip. Therefore, on all our lamps we mount the LED on highly efficient heat-sinks from which heat is transferred to all metal parts for maximum cooling.
Only this optimized SUPRABEAM cooling efficiency ensures long LED lifespan and world-class performance.
*All our flashlights are tested not to exceed 45 °C (113 °F) on the core structure in an environment of 20 degrees Celsius. This applies despite being used with high-power rechargeable batteries, such as Li-Ion or NiMh.
