Beyond laboratory tests, the first prototypes undergo numerous field tests, allowing true-condition verification of the ergonomics, the comfort of use, and the reliability of the headlamp over time. The product will receive final approval only after many months of development and testing.

Petzl does tests regarding lamp watertightness, mechanical strength of lamps (drop tests, impact and crushing), the mechanical durability of moving parts, vibration tests and finally the individual inspection of each lamp, in terms of manufacturing quality as well as lighting performance.

The laboratory tests are done at an ambient temperature of 20 °C, then at extreme temperatures between -30 °C and +60 °C.
