Découvrez ici une liste de résultats scientifiques obtenus avec des systèmes de stérilisation par lumière pulsée. Les résultats sont souvent très différents et il n'est pas toujours facile de les interpréter. 

On peut toutefois en conclure que le dispositif d'électronique de puissance fournissant l'énergie ainsi que la lampe émettant le flash sont deux éléments particulièrement importants dans un système de lumière pulsée.

  • Les caractéristiques techniques du flash émis impactent fortement les résultats : la durée de l'impulsion, la forme spécifique de la courbe électrique et l'intensité modifient le spectre lumineux et son effet germicide. 

Certaines publications montrent donc que les chercheurs se sont basés sur un nombre très différent de flash durant leurs essais en obtenant des résultats variables.

Cette base de données sera régulièrement mise à jour. Elle permet d'avoir un aperçu des thématiques abordées mais aussi des résultats microbiologiques obtenus sur différents micro‑organismes, en fonction de la fluence et du nombre de flashs.
