Hello!
I have the following situation; my church has a large, round stained glass window (96in diameter) would we would like to illuminate at night, so it can be seen from the outside. We are looking at an electric light that would make the stained glass visible from the street.
The first attempt, a couple years back, was to place a single flood light 15 feet behind it, and turn it on; well, from the outside, it looks like there is a single light bulb behind the stained glass window, very bright, and the rest of the window is much darker. It does not look good, to say the least. Forward to today, where the problem landed on my lap.
I am thinking of a way to diffuse the light so that it does not look like there is a single source (or multiple sources) of light behind it. I'd like to have the light as uniform as possible.
I DAGS and a search in rec.woodworking, and all I have found were ideas for smaller windows, for which a single light would b appropriate. I know that churches in Europe illuminate their stained glass windows and that it looks really nice. What is it that they are doing right and that I do not know how to do?
Thanks in advance.
Pierre
