That has always been my biggest worry. I've never hung a book on my walls for fear of fading. Has anyone had any experience with this? I worry that even interior light could ruin a book...
A window-less room where the lights are only on when I'm in there - I'm not worried:
UV protection built into the frame isn't as important as what mschmidt is saying here--if you're going to hang comics and you don't want the colors to fade, you HAVE to control the light into the area ENTIRELY and keep it dark the entire time people aren't in the room. Sounds simple, but it really isn't. You have to use curtains that allow in absolutely zero light to the room if there are any windows at all...I almost never see people use the right types of curtains, or even if they do, I rarely see them used correctly, the rooms still get bathed with ambient sunlight. It also needs to be a room you don't go into very often, which is the opposite of what you end up wanting--you typically want to show a book off, so people tend to put them in offices, dens, or computer rooms where there's a lot of human traffic that leads to longer periods of light exposure. If you want to hang something in a higher-traffic area, make sure it's something you don't care much about, as you can expect it to fade over a 5-to-20-year timespan. I eventually gave up on this because I go in and out of most areas I'd actually want the comics to hang in, so I just hang low-grade cheapies that present well via the frame--and I'll eventually replace those with larger, poster-sized blowups because they're better than comics for wall-display purposes--they present MUCH better and are easier to see across a room.
As for the interior lighting, low-wattage standard light bulbs are great. I always forget this, but standard white bulbs are flourescent, right? Whereas the long bulbs people use in office buildings are incandescent? Or do I have that reversed? If I'm right that long-bulbs are incandescent, that's not what you want to use around paper and art at all, that type of light fades art--standard bulbs have much weaker light that minimizes fading.
Strike that, reverse it.
