ANSI FL 1-2009 standard

Since 2010, the Fenixlight company has listed the parameters of all new models in compliance with the American standard ANSI / NEMA FL 1-2009. This makes it more accurate to inform customers and makes it easier to navigate the range of various manufacturers, who also list the parameters of lamps according to the ANSI / NEMA FL 1 standard. Fenix is one of the first non-American manufacturers of LED flashlights which has decided to voluntarily comply with this standard. Other manufacturers using this standard include: Streamlight, Maglite, Surefire, Energizer, Duracell, Black Diamond, Princeton and others.

According to the ANSI/NEMA FL 1 standard, the following parameters are measured:

  • Luminous flux (lumens)
  • Intensity of light cone (candela) and afterglow
  • Length of battery operation
  • Impact resistance
  • Water resistance

Measurement conditions

Parameters of flashlights and headlamps are measured in a laboratory with fully charged batteries in an environment with an air temperature of +21°C (+3°C) and a humidity of 50-80%. Under other working conditions, their parameters may differ.

Differences in indicated luminous flux:

For old models of lamps produced before 2010 (for example, Fenix L2D), the luminous flux was calculated according to the specifications provided by the LED manufacturer. However, every lamp has certain losses in the optical system, and the performance of the LED also affects its heating. Therefore, for example, the calculated luminous flux of the Fenix L2D flashlight was 180 lumens, but the measured luminous flux according to the ANSI FL 1 standard is approximately 130 lumens. Therefore, the previously stated calculated values may differ by up to approx. 30% compared to the values measured according to the ANSI FL 1 standard. This should also be taken into account when comparing parameters with lamps from manufacturers who do not use the ANSI FL 1 standard and therefore may quote numbers more than 30% higher than the values measured in real operation according to the ANSI standard.

Standardized icons for lamps with measured parameters according to ANSI/NEMA FL1:

ANSI lumens

Luminous flux (lumens) indicates the total amount of light produced by the lamp. It is measured in a professional calibrated spherical integrator. The value is read in the interval between 30 - 120 seconds after switching on the flashlight.

ANSI candela

At a distance of 2, 10 and 30 meters, the illuminance value is measured in the most intense part of the light cone (usually the center) with a calibrated luxmeter. The intensity of the light cone is then calculated from this value, which is given in candelas (cd, candela).

ANSI afterglow

Afterglow is given as the distance at which the light intensity of the lamp drops to a value of 0.25 lux. This is approximately the intensity of illumination produced by the full moon under a clear sky. The value is read in the interval between 30 - 120 seconds after switching on the flashlight.

ANSI vydrz

The battery life time is given as the time until the light output drops to 10% of the initial value measured 30 seconds after switching on.

Impact resistance indicates the minimum height of a fall onto a hard surface (for example concrete) at which the lamp will not be damaged. The body glowstilny must not show any cracks and must be fully functional. The minimum drop height for the test is 1 meter.

ANSI waterproof

Splashproof

The ANSI FL 1 standard recognizes the following types of water resistance:

  • Resistance to splash water (IPX4) and resistance to heavy splash water (IPX6)
  • Resistance to short-term immersion in water to a depth of 1 meter (IPX7)
  • Resistance to continuous immersion in water to a depth greater than 1 meter (IPX8)
