Ornamental Street Lighting

Take the mere matter of "glare," for example. Glare is the result of looking at a light instead of seeing by it. Better than any man, the motorist knows what glare is. When he drives from a dark spot toward an intense light, he finds that he cannot see beyond the light; accordingly he sits back and trusts to luck that there is no person or obstruction beyond. The illuminating engineer-the man who specifies the kind of lights you ought to use and where they are to be placed-now knows that glare is produced by hanging an excessively bright light so low that the rays enter the eye nearly horizontally, with the result that every image on the retina is drowned. Therefore he avoids it so far as he can.
