NIGHT TRAIL RUNNING 41 Contents Assembling over 5500 runners for a series of four ultra-trail running races, The North Face ® Ultra Trail du Mont-Blanc ® is the queen of mountain trail runs. The main trail covers 166 km, with 9500 m of elevation gain around the giant of the Alps. On the agenda: intense heat, thunderstorms, showers, strong winds, thick fog, ice and snow, but also brilliant sunrises and sunsets, starry skies... Sébastien Chaigneau lived through all that for 20 hours and 55 minutes, until he reached the third step of the podium. © Franck Oddoux, Hervé Bodeau
NIGHT TRAIL RUNNING Declining lighting or constant lighting? 42 Contents © Lafouche In 2000, the TIKKA was introduced as the first compact LED headlamp. Since then, technology has continued to evolve: as a reference, the first TIKKA provided 9 lumens of maximum lighting. Today, the TIKKA XP 2 delivers 80 lumens of lighting power in maximum mode. LEDs have also allowed headlamps to become extremely light and compact, and characterized by very long lighting duration. While the LED revolution has been significant in terms of power, the technology of the batteries themselves has not evolved proportionally. Concretely, the more powerful the LEDs become, the more energy they consume. Consequently, in a classic energy management model, the brightness of the headlamp will rapidly decrease in declining mode. Headlamps that allow constant lighting offer an alternative for maintaining brightness. Declining lighting Most compact headlamps provide brightness in declining mode, i.e. with an uninterrupted decline in power from the moment they are turned on. This drop in lighting power varies depending on the LEDs, the type of batteries, etc. For example, with a TIKKA XP 2 the light quantity is 80 lumens when first turned on using new batteries, and it is 54 lumens after the first half hour of use. After 80 lhours, the light output is considered unusable (below 0.25 lux, the equivalent of the light emitted from a full moon on a clear night). Headlamps with declining lighting offer longer lighting duration and high light output at the beginning of use. They are a reasonable compromise between light output and battery life. However, for many activities it is more important to have constant light quantity over a designated period of time. Constant lighting With this type of lighting, the lamp's discharge cycle is treated differently: the light output is constant during the specified battery life of the headlamp (outside of reserve lighting). With a TIKKA XP 2 with its rechargeable CORE battery configured for constant lighting, you will always benefit from the same quantity of light, whether you go for a one-hour or a four-hour run.
