Question on lighting/fading cards and autos

[Exhibitman]

All light regardless of source damages art and antiques. The question is how to mitigate if you want to display items. Standard practice in museums is to avoid direct light of any kind and to put items on display for short periods. Paper is especially vulnerable to light damage.

As for fluorescents, museums don't use them because they throw off comparatively high levels of UV rays that can damage artwork. If you have SGC slabs in exposure to fluorescents on an ongoing basis, check the flips on cards that are in fluorescent lighting--the flips will turn brown from exposure to fluorescents. Even if the cards still look good, the flips will be the canaries in the coal mine.

As for damage, a day in direct sun can brown paper and fade colors. I have seen cards displayed in collections using direct fluorescent lighting systems where the card colors are significantly degraded. Cards that I've noticed taking an especially bad hammering relatively quickly are 1930s Goudey and 1950s Topps issues.

Assuming you aren't hanging your items in direct sunlight, the easiest way to mitigate light damage is to frame your stuff behind UV-resistant glass or plexiglass and to never shine a fluorescent or other direct spotlight on your items.

I run color copies of my items for displays and put the originals away. Total peace of mind...

Three things you can do:

1) Holders that protect against UV rays. Many probably do these days

2) Incandescent lights are better than fluorescent. Give off less UV.

3) Overall limit light exposure in whatever ways. For example, if you're going to be gone for 12 hours, don't leave the lights on, shades open. That would be useless light light because no one will even be there. Don't put the autograph in direct window sunlight when it could be as nicely displayed in in a windowless hallway.

I think some damage to baseballs, signatures whatever isn't caused by light. It can either happen naturally, via head humidity etc. I'm sure you'll hear about someone who kept a ball in a box in a dark closet for 10 years and the signature ink changed color and the ball toned. Remember, baseballs are made out of cow skin-- which doesn't sound as if it would be the most eternally stable material.

All of my cards are in screwdowns displayed in custom made wooden cases. They are in a room with no windows and normally totally dark.
However, the lighting in the room is fluorecent tubes.
Is there any real danger as the light on on less than 1 hour per day?
Are there alternative bulbs etc?
Thanks

The situation you describe sounds fine to me, even if you stick with fluorescent. With the amount of light you describe, fluorescent isn't a big concern and I wouldn't worry about it. One hour a day of light is close to nothing.

I'm most concerned with people who keep things in an office with bright lights 14 hours a day, or have them displayed in a brightly sunlight room-- the stuff sitting in direct sunlight for 8 hours ever day. And, even then, if they used UV protectant glass or holders, that would still prevent a lot of the damage. Like wearing sunscreen before going out into the Arizona sun.

Cards are a LOT more stable than autographs and photographs. Lithographs (as in Topps, T206s, Goudeys) can fade with lots of exposure, but should stay fine under normal conditions.

Google "uv fluorescent tube guards", or some permutation of that... there are tubes of film that will cover a normal fluorescent tube, the tube filters the uv light out.

Use special uv bulbs, or uv tubes / guards, or put the items behind uv protective glass... and minimize the light.

The light just wears out cards, photos, and autographs...
