Ever wonder how NEMA (H x V) Classifications are derived, or how they relate to the performance and design application of a floodlighting distribution? How about beam and field angles, and maximum candela values?

-Maximum Candela is defined as the maximum candela value emitted from the luminaire in any given direction.

-Beam angle is defined as the included angle between points of 50% of Maximum Candela.

-Field Angle is defined as the included angle between points of 10% of Maximum Candela.

As an example, a distribution with a 50,000 Cd maximum candela value

as shown in the intensity distribution graph to the right (FIG. 1) would have a Beam Angle defined by the included angle of 25,000 Cd values, and a Field Angle defined by the included angle of 5,000 Cd values.

E X A M P L E

Max Candela = 50,000 Cd

Candela Value defining Beam Angle = (50% * 50,000 Cd) = 25,000 Cd Candela Value defining Field Angle = (10% * 50,000 Cd) = 5,000 Cd Beam Angle = 90°

Field Angle = 120°

NEMA classifications are extrapolated from the table below and are determined by a distribution’s Field Angle. This relative classification is used to describe the general shape and application of a distribution. NEMA classifications are used to classify both the horizontal and vertical components of a floodlight distribution.

The example distribution in FIG. 1 above would have a NEMA Classification of 6 as the 120° Field Angle falls between the 100-130° range.
