ANSI/NEMA FL-1 standard
B. According to the ANSI Standard, Fenix tests the beam distance.
Beam Distance Test: To place the luxmeter at a test distance of either 2 or 10 or 30 meters from
the lens of the device to be tested. Use the luxmeter to identity the brightest point of the beam
pattern and record the highest indicated in value.
To determine the beam distance, the Inverse Square Law formula is used:
√( peak beam intensity (cd) /0.25 (lux)) = Max Beam Distance (m)

test the beam distance
