To have a clearer understanding, here are few examples for various commodities:
Indian Standards Institute | Products deemed for safe consumers use.
ANSI (American National Standards Institute) | ANSI represent more than 270,000 companies, professional societies, trade associations, government agencies, and consumer and labor organizations. ANSI lobbies for over 30 million professionals and covers nearly every industry across the globe
American National Standards Institute (ANSI for short) was established in 1918. It is a non-profit non governmental standards institute.
ANSI is one of the five permanent members in International Standardization Organization (ISO for short) as well as one of the four permanent members in the
International Electrotechnical Commission (IEC for short). It takes part in 79% activities of ISO/TC and 89% activities of IEC/TC. ANSI is a member of COPANT and PASC respectively.
ANSI is the potential national standards institute and actually it has turned into the national standards center. Various standardizing activities have connections with
it. In the meantime, the ANSI Standard has been voluntarily adopted.
For a long time, there had been no standardised tests or uniform rating systems for consumers to judge flashlight performance. Without any uniform rating systems, it frustrated the manufacturers who were working hard to make high quality lighting tools.
The establishment of ANSI/NEMA FL 1-2009 Standard allowed consumers to compare flashlight performance. The standard provides a guide for consumers to rate and compare the claims on the packages for each manufacturer’s products.
Distributors and consumers are more informed. Therefore, it is much easier for them to make the best choices for their needs.

Representatives from 14 illuminating companies, such as Princeton, Surefire, Petzl, Streamlight, Black Diamond and Duracell, etc. Representatives from flashlight users and flashaholics
The ANSI Standard helps the consumers know about the technical parameters of flashlights quickly which allows them to make a comprehensive comparison of various flashlights.
It can provide a guide for distributors and end users to know more about the products and make the best choices for their needs. It evens the playing field for those manufacturers that participate. It’s important to know that adherence to these standards and reporting results is strictly voluntary. Many leading flashlight manufacturers are now adopting the standard.
A measurement of the total quantity of emitted overall light energy as measured by integrating the entire angular output of the portable light source. Measured in Lumens.
To measure the quantity of overall light energy emitted by the device.
Power resource: All tests are conducted with fresh batteries or fully charged batteries. Batteries used shall be of the same type and/or brand as of the product. The batteries recommended by the manufacturer are to be used for testing. .
The duration of time from the initial light output value (that’s 30 seconds after the light is turned on with fresh batteries) until the light output drops to 10% of the initial value.
To determine the amount of time elapsed under continuous operation at every level.
Conditions: If the device offers multiple output levels, the runtime will be measured at the maximum level & at every level.
The distance from device at which the light beam is 0.25 lux. Results are reported in meters
To determine the maximum distance at which the devices is capable of producing 0.25 lux of light within 30s to 2 min of operation.
Peak beam intensity is the maximum luminous intensity typically along the central axis of a cone of light. The value is reported in candela and does not change with distance.
To determine the peak beam intensity, reported in units of candela, of the device’s beam pattern within 30s to 2 min of operation.
The degree to which a portable light resists damage when dropped on a solid surface. Dropped samples must remain fully functional in order to pass the impact resistance test.
To ensure the structural integrity of hand-held/portable lighting devices under specified impact conditions. The test procedure provide specifications and methods that will ensure products meet a minimum standards of reliability as a result of impact testing.
Drop test should be a priority to any other reliability tests, shall be 1m minimum.
Purpose: The flashlight water resistance can satisfy the lowest requirements for the reliability.
All test samples shall function normally immediately after the test and 30 min after the test.
Water Resistance measured in regards to:
Resistance to Temporary Immersion in Water
Resistance to Continuous Immersion in Water
Resistance to Splashing Water
Fenix will spare no efforts to provide more reliable products and perfect services. The consumers can better evaluate, compare and choose their products provided that they know about the output, beam distance, impact resistance, water resistance and the runtime.
It will adhere to ANSI/NEMA FL1-2009 Standard with all its products.
In line with the ANSI Standard:
