Why is the ANSI/PLATO FL 1 2019 Standard important?

Buying a flashlight, headlamp, bicycle light, or spotlight can be a confusing proposition to most consumers and many retailers, but the ANSI/PLATO FL 1 2019 Standard and PLATO are two key resources that provide clarity for buyers and accountability for the industry. The ANSI/PLATO FL1 2019 Standard, developed by PLATO, industry experts, and stakeholders, spells out specific testing and reporting methods for portable lighting products that emit directional light. If the ANSI FL1 icons are present on the packaging, consumers and retailers can be confident that the reported performance claims are tested to industry standards, and even more importantly, the consumer can compare “apples to apples” when evaluating different products.

How does PLATO uphold the Standard?

Through independent, third-party testing, PLATO provides industry oversight to ensure portable lighting products meet or exceed the ANSI/PLATO FL 1 2019 Standard. PLATO informs manufacturers of any issues uncovered by the testing process and attempts to work collaboratively to resolve discrepancies between test results and product markings.

Who was involved in the development of the ANSI/PLATO FL 1 2019 Standard?

As an Accredited Standards Developer, PLATO is proud to have worked autonomously to revise the ANSI/NEMA FL1 Standard to create the ANSI/PLATO FL 1 Standard, which was released in October 2016. PLATO went through a similar process three years later and added area lights and published a revised ANSI/PLATO FL 1 2019 Standard. The Standard strengthens the portable lights industry by providing more credibility to those portable lights companies correctly using the standard and its icons. The ANSI/PLATO FL 1 2019 Standard was developed by the PLATO Standards Committee. At the time it was approved, the PLATO Standards Committee was composed of the following members:

• ASP, Inc. Appleton, WI 54912
• Cat Eye Co., Inc. Boulder, CO 80302
• Coast Portland, OR 97218
• The Coleman Company, Inc. Wichita, KS 67219
• Dorcy International Columbus, OH 43217
• Energizer Holdings Westlake, OH 44145
• Insight 2 Design, Inc. Overland Park, KS 66221
• Leatherman Tool Group, Inc. Portland, OR 97294
• Nite Ize, Inc. Boulder, CO 80301
• Panasonic RTP, NC 27709
• Streamlight, Inc. Eagleville, PA 19403

What does each icon mean?

Below are the icons and an explanation of each specification.

Light Output


Total light output measured in Lumens. Lumens have become the most commonly used unit of measure for total light output in portable lighting devices. The wattage, on the other hand, is a measurement of power consumption, not light output. With today’s efficient LED technology, it’s very possible to have a lower wattage LED flashlight with a greater light output than another flashlight with a higher wattage rating. This is the reason why Lumens have become the best comparison method.

Beam Distance


Beam Distance

The distance, measured in meters, at which the light projects a useful amount of light, measured at 0.25 lux. (0.25 lux is approximately the equivalent of light emitted from a full moon “on a clear night in an open field.”)

Run Time


Run Time

Tested with fresh batteries from 30 seconds after the light is turned on until the light output reaches 10% of the initial measurement. This is the total time of useable light before most consumers will change batteries.

Peak Beam Intensity


Peak Beam Intensity

The brightest point in the beam is measured in candela. Candela is the modern unit of measure for light intensity replacing the now-obsolete unit known as candlepower.

Impact Resistance


Impact Resistance

The height, measured in meters, from which the light can be dropped onto cured concrete and still work properly. This testing is completed by dropping the product (6) times using drop orientations that approximate each side of a cube. Dropped samples cannot have any visible cracks or breaks and must remain fully functional. The product must meet a minimum of (1) meter to receive this rating.

Water Resistance

Water Resistance

This icon indicates an IPX4 rating which means the sample is tested against water sprayed from all angles. If this test is performed, it must be done after impact resistance testing is completed to ensure water resistance under real-life conditions.

Water Proof



Water submersion depth rating, measured in meters. This icon indicates at least an IPX7 rating which means the sample is submerged to a minimum of 1-meter depth for 30 minutes. If this test is performed, it must be done after impact resistance testing is completed to ensure water tightness under real-life conditions.

Women may be at risk while walking in the dark due to an increased risk of violence and sexual assault, especially in poorly lit areas. Carrying a gun for personal safety is a contentious issue that can come with significant risks and responsibilities. In many places, carrying a weapon is illegal and in an attack situation, weapon-carry requires rapid deployment, knowledge of use, and willingness to use. Instead, a portable flashlight can be a good option for personal safety because it can provide light in dark or poorly lit areas, as well as temporarily blind or disorient an attacker.

Because of the hands-free functionality and flood beam profile, headlamps are often the preferred lighting tool of choice. However, there are hundreds of different headlamps to choose from on the market, and not all headlamps are created equal.

Firstly, consider the activities for which you intend to use your headlamp. Once you have a clear idea of how you intend to use your headlamp, consider what you require your light to do for you.

Nowadays, a flashlight with thousands of lumens is quite common, but due to overheating issues, most can only stay in turbo mode for a few seconds. Even if it steps down to a lower level, it won't last long. A few high-quality flashlights, on the other hand, can stay in turbo mode for a few minutes at a few thousand lumens and then light up steadily for hours after stepping down to a lower, but still high lumen output. Do you understand why there is such a significant difference?
