I'm in the process of quoting to illuminate a bit of listed stained glass and am looking at LED options. One concern is what effect the LED may have on the glass in the long term, will it affect the pigmentation at all?
White LEDs affect regular theatrical colour filters at a surprising rate, especially blue filters and this glass just happens to be blue.
I'm wondering if there would be any advantage in lighting it indirectly using a reflector to bounce the light onto the glass rather than directly lighting it? I'm effectively going to be building light boxes behind the glass so could easily achieve this.
