The lighting load¿its characteristics and development

The author discusses the growth of the lighting load during recent years, and directs attention to the trend in its characteristics for various uses. It is shown that, while the demand for lighting consumption is increasing, there is a simultaneous improvement in load factor. Proposals are put forward for developing the lighting load, and especially opportunities for obtaining increased revenue per pound of capital expenditure by encouraging higher lighting levels and their more extended use. The author urges the appointment of lighting development officers to call at regular intervals on shops, factories, hotels, etc., offering suggestions to improve lighting conditions. It is claimed that the added revenue obtained from giving such services more than meets the expenditure involved. An estimate is given of the potentialities of the lighting load in Great Britain, assuming reasonable increments in lighting levels.
