I have an old house with a charming porch light. It's so old that the glass shade is turning violet, and I hate to replace it. Unfortunately, it is also mostly unshielded, except for the receptacle at the top. I use the smallest wattage incandescent light that I can find, usually 15, or 25 watts, at the most, and yes, I leave it on all night. Even looking directly at it, there is virtually no glare/discomfort, and it's by far dimmer than the street lights and neighbors' lights. I guess I might be making excuses, but I have no problem with this solution. As an architect, I have to deal with need to light many buildings and sites. I insist that my electrical engineers use shielded lights, and we usually look for solutions that direct the light downward. One project I worked on that was an early effort, at least for SLC, to use downward-directed, shielded lights is the Gallivan Center Plaza downtown. I think it was very successful in that regard. Has anyone noticed, after almost 15 years? Kim
