New ANSI FL1 STANDARD

Further Information

ANSI FL1 STANDARD – FOR AN OBJECTIVE COMPARISON

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.

 

The comparable features of VARTA flashlights in accordance with the ANSI standard

  • Beam Range: ANSI states that the beam range is measured as the distance between the flashlight and the point where the light beam is a minimum of 0.25 lux (0.25 lux roughly corresponds to light emitted by a full moon on a clear night in an open field).
  • Battery runtime: This is defined as the amount of time between switching the flashlight on and the moment when the light output drops to just 10% of its initial value. It refers to the battery run time with the flashlight in constant use, without being switched off.
  • Light output/luminous flux: This is measured in lumens. It refers to the total quantity of visible energy emitted by the LED within a particular frequency range that we perceive as light.

VARTA communications and performance data fully conform with the ANSI standard. Fair comparisons can, however, only be made if the other products being compared also conform with this standard
