Most all glare comes from poor fixtures or poor installations. There is no need for any of it. Use the right amount of light for the task, not overkill. When not blinded by glare, the eye is a marvelous instrument and can see very well at what seems to be quite low lighting levels. Use energy efficient light sources.
Light sources vary greatly in their efficiency.
LPS is excellent for street lighting, parking lots, security lighting, and other applications where color rendering is not critical. Careful lighting design can be done using LPS for essentially any application. Progress in Implementing Solutions Quality lighting design is being used now in many locations, such as Tucson. We all really do win. Awareness of the problems and of the solutions is increasing rapidly, in the public area and especially in the lighting community.
