Scientific paper

In an earlier paper (Bull. AAS. 30, 838, 1998; Mem. Soc. Astr. Italia, in press, 2000) I studied the effects of population growth and of smog on the historical growth of light pollution at Mount Wilson. I have now done some very crude calculations to evaluate the effect of changes in lighting technology - the most important change being from incandescent lamps to mercury vapor lamps to high pressure sodium lamps in street lighting. I am greatly indebted to George Eslinger, lately Director of the Bureau of Public Lighting of the City of Los Angeles, for information on the numbers and types of street lights in that City. The ratio of numbers of lamps of different kinds throughout the Los Angeles basin at any given date has been assumed to be the same as in the City. The contributions to the photon output in the B and V photometric bands have been estimated. The calculations show a rate of increase of the V brightness greater than that obtained if lighting changes are neglected. The B brightness shows a maximum during the period when mercury vapor street lighting predominated. I hope to refine my calculations when additional information becomes available.
