NEMA FL-1 Standards

NEMA FL-1 Standards

NEMA, produce a set of international standard that LED torches; should be rated against.  First released in 2009, these standards are not compulsory for any torch company but are supposed to give the customer a fair way to compare torches.

The icons are shown (right) indicate the important specifications for a torch.

Peak Beam Intensity Sample Size = 3
What it tests: The maximum luminous intensity of the torch, usually along the center of the beam.
How we test it: Beam spot measured at 2m from the torch

 

 

Run Time Sample Size = 3
What it tests: The time the torch can produce light, taken from 30 seconds after turn on until light output reaches 10% of the starting value.
How we test it: Record time taken to get to 10% of starting brightness, average 3 measurements
Beam Distance Sample Size = 3
What it tests: The distance from the torch where the light beam reduces to 0.25lux.

 

How we test it: Beam spot measured at 2m from a torch, average 3 sets of results

 

 

Light Output Sample Size = 3
What it tests: Total luminous flux of the torch, as measured using an integrating sphere.
How we test it: Measure torch output using integrating sphere, average 3 results

 

 


Enclosure Protection
Sample Size = 3
What it tests: Test for the degree of water resistance of the torch.
How we test it: Test samples to a minimum of 100m for 30 minutes.

All torches exceed IPX8 = Immersion beyond 1m

 

Impact Resistance Sample Size = 3
What it tests: Resistance to damage when dropped on a solid surface.
How we test it: Drop from 1m onto solid concrete

Each sample to be dropped 6 times, in different orientations
