What are the basic performances standard of led flashlights

2018-07-10

led flashlight basic performance standard,Introduced in 2009, ANSI FL1 standards for flashlights.It ensure that models are tested and rated in the same way. The led flashlights manufacturers can do their own testing,also customers can choose the right flashlight according to the standard.Now most flashlight brands include the following basic performance standard data on their packaging.

LED Flahlishgt Light Output

Measured in lumens. This is a measure of the intensity of the light coming out of the flashlight, on the highest brightness setting powered by new batteries.It may also be shown for multiple light settings. This is a great comparison tool, but does not tell the whole story about brightness. Beam intensity, distance and type all influence the effectiveness of a light in different applications.

Beam Distance

Measured in meters. This is how far the LED flashlight will shine before the brightness diminishes to the equivalent of the light from a full moon. This distance will vary with the brightness setting selected.

Flashlight Run Time

Measured in hours. How long does it take the light output to drop to 10% of the rated output on new batteries. Flashlight output may gradually decrease over time, or remain largely constant and then suddenly decrease. Run time is commonly given for each light setting. Run Time is the important basic performances standard of flashlights.

Water Resistance

Rated using the IPX system. Water resistance is important standard if using your flashlight in the rain or around bodies of water. Two ratings are used:

Indicates a water submersion rating, also after the impact test.

IPX7 – temporary immersion: up to 30 minutes at a depth of 1m.

IPX8 – submersion: up to 4 hours at the specified depth.

Impact Resistance

Measured in meters. Lights are tested by dropping them 6 times onto concrete at the rated distance. This test is primarily to ensure the light remains functional after occasional accidental drops. It is not a test of resistance for a light being run over, being struck with a heavy object or being used to strike other objects.

The key factors to compare when selecting a led flashlight.if you understand the basic performances standard of led flashlight.it can help choose a right flashlight.
