3. Exterior Lighting Design

The design process for the floodlighting of functional areas normally consists of three stages:

(a) A practical assessment is conducted to:

(i) locate floodlights,

(ii) select the type of light distribution, and

(iii) identify the light source characteristics which suit the particular application.


(b) Lumen calculation is carried out to establish the number and loading of lamps to achieve the required average illuminance.


(c) When necessary, point-by-point calculations are performed to determine the aiming pattern of floodlights for the required uniformity.
