My collection on the wall. Is sun gonna ruin them?

Fluorescent lighting works by (skipping a few steps) creating ultraviolet radiation and then using fluorescence (hence the name) to convert it into the spectrum we can see. Some ultraviolet radiation is emitted though.

Guys...LED lighting is still untested and may not be as harmless as we all think, from all that I have read. Incadescent bulbs are still the best and least abusive to collections.

Get some blinds and window coverings. Do not leave the lights on unless you are down there enjoying your collection and you should be fine.

That article, and other published at the time, are misleading, and their conclusions were not included in the journal articles as they would not have passed peer review for multiple reasons. Its to much information for me to go into here but I will include a few links that discuss the topic in depth.

Museums Are Starting To Use LED Lights To Preserve Their Paintings - Tech Times

A few years ago, the Smithsonian held a symposium on the use of LED's in museums. There is about three hours of presentations by conservators, lighting engineers and designers et cetera on their youtube page.

One of the talks not listed was given by Jim Druzik, Senior Scientist at the Getty Conservation Institute, and Dr. Michael Royer, a Light Engineer at the Pacific Northwest National Laboratory. It directly deals with the Van Gogh painting.

Wow, great info, thanks! It makes it tough when there are differing opinions out there, but it looks like LED lights are for sure better than fluorescent, but I still trust incandescent more. I don't use any high powered bulbs, so the heat effect is not an issue like it might be in a museum or something.
