In August 2009, the American National Standards Institute (ANSI) published the ANSI FL1 "Flashlight Basic Performance" standard (developed by the Flashlight Standards Committee). Although originally only intended for use in the United States, the world's first flashlight norm has become the world's leading flashlight standard. It includes precise definitions of terms, marking rules and test methods for measuring the relevant performance parameters of portable lights.
The clearly defined test methods and marking rules help retailers and consumers to understand and compare performance features more easily. That is why VARTA has become one of the first manufacturers in Europe to adapt its measurements of flashlight performance consequently to this new standard.
The American National Standards Institute (ANSI) is a private non-profit organization that monitors the development of voluntary standards for products, services and processes in the United States. The organization coordinates US standards with international standards to enable international product comparisons to be made.
