Summary: "We calculated that 16 hours of LED illumination corresponds with several hundreds of years of illumination by museum light". The article offers no further explanation or citation.

I had read that LED lighting is now recommended as a replacement for tungsten in archival situations. Is that wrong?

It's just that they used LED to illuminate the copper pigment samples equivalent to many years of otherwise dim museum lighting.

The summary of the article is in the chemistry of the pigment, not the technical details of re-creating the effect.

The article doesn't mention what kind of LED lights were used. They probably used LEDs that emit light in the UV spectrum (like sunlight). They would probably get similar results if they put the pigment in a tanning bed.

I feel like we need to have Journalists follow the rule of 5-whys. Ask 5 whys until you get enough depth to write an article.

But that's not because journalists aren't capable, its that these days audiences freak out when they see anything more than tabloid level detail in an article. In-depth discussions are glossed over, they don't fetch views and subscriptions. Masses want entertainment instead of information. So, there is no incentive to write deeply studied articles.

I appreciate your desire for deeper analysis, but I hate the "5 whys" as they imply every event has a single root cause.

That's an implication you're imposing yourself: there's no reason why asking the answer to any single question looking for cause will only have a single cause. Even Wikipedia's cursory overview includes this:

> "Not all problems have a single root cause. If one wishes to uncover multiple root causes, the method must be repeated asking a different sequence of questions each time."

Particularly if you're aware of a tendency to limit to a single root cause, you can actively work to ensure you don't fall into that trap.

If you clicked on the article, that's all the author needed. And to get you to click, all they needed was a catchy headline. It's the unfortunate reality of modern journalism. See the book "Trust Me, I'm Lying" by Ryan Holiday.
