George, in a private showroom at the Colt factory the lighting was fluorescent & was left on 24 hours a day. About once a year + the SAA were removed due to fading on the display side to be redone. I agree, UV seems to wash out colors. In fairness, I have heard others say the same as the good Dr. Also, I have left a coupon that is CCH in my shop window for the past three years that hasn't faded one bit. I donno, looks like a toss up. FWIW
Ken,
This is very true about fluorescent lights. For alternative photographic prints, eg Platinum, Cyanotype, etc a light box is constructed of fluorescent tubes because of the potential for high UV output. Even the new compact fluorescents put out some amount of UV. It is easier to gain control than using the sun.
The only alternative is to choose tubes with very low UV output and use UV resistant glass in the cabinets.
