4- Efficient Lighting Design:

The lighting design should achieve the desired parameters with optimum solutions. Let us consider the following example of designing the lighting for an office with two different configurations. An office working area is 5m x 10m as shown in Fig. (Working space lighting using 4x28W fixtures). In this solution; a very efficient fixture is used with 4x28w lamps and electronic ballast; which means that all the parameters of an efficient lighting source are fulfilled. However, using this type gives the following results for the workplane: 688 average lux and 0.553 uniformity. The total consumed power for this solution is 732W.
