Find out what light sources will fade artwork and fabrics
Traditional incandescent lamps can damage art over time. Consider a high-CRI LED source instead.

Q. : Some light sources are known to accelerate the fading of fabrics and artwork. Is this an issue with the new ESL bulbs?

A. : You're right, different light sources accelerate fading at different rates. It depends on the amount of ultraviolet (UV) light each particular light source produces. The worst culprit is natural daylight, followed at a distant second by incandescent and finally fluorescent. ESL (electron stimulated luminescence) bulbs are still close cousins to fluorescents in the way that they create light. These bulbs produce close to the same amount of UV as other fluorescent bulbs. Their main advantage over other fluorescents is that they contain no mercury. Fluorescent bulbs produce a small amount of UV, and until LEDs came on the market, they were the best bet. Only LEDs, which produce no ultraviolet light, completely protect fabrics and art from fading. Even if you are using LED sources, however, most rooms have windows that allow natural light in during the day. This will cause fabrics and art to fade over time. Closing the window shades during the day will help protect your possessions, but it will make the space feel a bit depressing. I recommended watching a John Hughes film. It always makes me feel better.

Thanks for the note on UV levels and light bulbs - I hadn't known LED bulbs emitted no UV light.

Regarding outdoor UV, I definitely would like to keep the window shades open. What do you know about the UV protective window films that are on the market? Are they a good solution?
