INTRODUCTION

Flood lighting luminaires are used for the lighting of public thoroughfares, roadways and signs, contributing to road safety as well as public safety. The reliability and safety of the control gear (ballasts, capacitors and ignitors), and hence the luminaires, have a direct impact on levels of customer satisfaction as well as quality of supply. As this is difficult to manage within the present City Power business structures it has been decided that SABS support structures will be relied upon to manage compliance to specification as well as quality. The implication to suppliers is that City Power will only purchase floodlights that bear the SABS mark.

1 SCOPE

This specification covers City Power’s requirements for the manufacture, testing, supply and delivery of floodlights in accordance with SANS 1279 and/or SANS 60598.
