Where:<br />
nNRA = nano NVIS radiance requirements for Class A equipment.<br />
nNRB = nano NVIS radiance requirements for Class B equipment.<br />
"nano", abbreviated "n", represents a factor of 10 -9 , which is factored out of the radiance numbers in this table.<br />
cd/m 2 = Candela per square meter, sometimes called "nits".<br />
NOTE 1. For these <strong>lighting</strong> components, Class B equipment shall meet all Class A requirements of this specification. The relative NVIS response<br />
data for Class A equipment, GA(λ) (table III.a.), shall be substituted for GB(λ) to calculate NVIS radiance.<br />
