FLASHLIGHT ANSI STANDARDS

While Peli was one of the first manufacturers to use quantifiable test procedures, the need was recognized to develop a common language that customers could use to select the right flashlight for their specific needs.

As a result, the American National Standards Institute (ANSI) with input from the flashlight industry, developed performance standards and symbols to effectively communicate a flashlight's features and benefits.

Resulting ANSI/NEMA FL 1 Standards include the six criteria described below:

LIGHT OUTPUT
Light Output is the total luminous flux. It is the total quantity of emitted overall light energy as measure by integrating the entire angular output of the portable light source. Light output in this standart is expressed in units of lumens.
RUN TIME
Run Time is defined as the duraton of time from the initial light output value – defined as 30 secons after the point the device is first turned on – using fresh batteries, until the light output reaches 10% of the initial value.
BEAM DISTANCE
Beam Distance is defined as the distance from the device at which the light beam is 0.25 lux (0.25 lux is approximately the equivalent of the light emitted from the full moon "on a clear night in an open field").
PEAK BEAM INTENSITY
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.
IMPACT RESISTANCE
Impact Resistance is the degree to which a device resists damage from dropping on a solid surface.
IPX4 WATER PENETRATION RATINGS

IPX4 - Water Resistance - Water splashed against the device from any direction shall have no harmful effects.

IPX4 / IPX7 WATER PENETRATION RATINGS

IPX7 - Water Proof - Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standardized conditions of pressure and time.

IPX8 - Submersible - Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is continuously immersed in water under conditions which shall be stated by manufacturer, but which are more severe than for IPX7.
