AIMING POINTS

There will be wasted light when the

floodlight is aimed at the far edge of

the area to be illuminated.

Aiming the floodlight too close to

the near edge causes low level

illumination at the far edge.

Good judgement in aiming floodlights

is to aim them two-thirds of the

distance to be lighted.

Aim floodlights at 30° below the

horizontal to achieve better visual

comfort. Mounting height may need

to be increased to accomplish 30°

below horizontal.

Where the edge of one beam

intersects the aiming point of the

next floodlight, there is more

uniform light distribution.

How to Floodlight

NEMA Beam Classifications

National Electrical Manufacturers Association (NEMA)

classifications are 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.
