Electric lighting for building sites and construction

Abstract

Lighting for building sites and works of engineering construction has developed rapidly over the past few years. There has been growth in the number of sites equipped with electric site lighting, and an increase in the number of sites employing electrical energy for other building purposes. Site lighting seems to be progressing from improvised systems hastily erected to cope with unanticipated lack of light, towards well-engineered systems planned as part of the efficient operation of site activities. The techniques of lighting have changed and become simpler, and the types of luminaires are more suited to the needs of today. Higher illuminances are being employed, but tentative proposals are made for still better standards. The subject of site lighting is reviewed and some recommendations are made for future development and for the efficient and safe use of electric lighting on sites.
