Authenticity is Everything
We're testing design changes tonight. Things may look or act weird on and off.
Hang in there.
Incandescent lighting and autographs on paper
I know that all types of lighting can potentially damage autographs by causing fading. If I remember correctly from things I’ve read, however, incandescent lights give off a very low level of UV light. Is that true?
So please consider this scenario. I like to sit at the kitchen table at night and casually look at some of my autographs. When I do so, I have a couple of incandescent lights placed about 5 or 6 feet above my autographs, autographs that are on pieces of notebook paper in ballpoint pen or small-tip fiber pens or markers. If the only lighting the autographs are receiving is the incandescent lights previously mentioned for 5 or 6 hours potentially, do I need to be realistically concerned about fading over time?

Great question, James. LED lighting generally produces very little UV light and they're often used in art and other museums. They're worth researching.

And little heat, even with high illumination! You average 4-9 watt LED "light bulb", generates as much light as the average 60 watt incandescent filament bulb, with 1/10th of the heat, if any!

As far as incandescent lights go though, they generally aren’t very harmful to autographs are they?

Yes. Placement is crucial. No direct light. Indirect only and not close enough to be "warmed" by the radiant heat.
