As winter approaches, visibility becomes a priority for cyclists. But not all headlamps are created equal. The latest comparative test conducted by several European automobile clubs, including the ACL, examined eleven models of bicycle lights with a claimed output of 100 lux, ranging in price from €33 to €199. The aim was to assess their actual performance, durability, ergonomics and ability to illuminate without dazzling.
Before getting to the heart of the matter, it is important to discuss the methodology used. The tests were carried out in accordance with the criteria of DIN 33958, with enhanced procedures to reflect modern requirements. Each light was tested on a standard trekking bike, in the laboratory and on a test bench. The evaluation criteria included:
- Handling and installation: ease of mounting, stability of the mount, ergonomics of the buttons.
- Lighting characteristics: light intensity measured in lux, beam uniformity, side visibility.
- Operating time: in maximum and economy mode, with measurement of time until shutdown.
- Recharging: port type (USB-C or micro-USB), charging time.
- Water and shock resistance: simulated rain and drop tests from 1.1 metres.
