Development and testing
To ensure excellent performance and quality for each product, all Petzl headlamps undergo different mechanical, electrical and optical simulations during their development. These tests adhere to rigorous protocol, with requirements that significantly surpass those imposed by the common standards. This particularly strict process ensures that each technical solution is inspected during use, and that the relevance of the product is checked.
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 tests are done at an ambient temperature of 20 °C, then at extreme temperatures between -30 °C and +60 °C.
