Did you ever notice old plastic cased computers turn yellow with age? Mostly on the side facing windows with exposure from sunlight. But also on the areas exposed to fluorescent lighting in offices.
I have old computers and toys in rooms with only incandescent lighting, and they don’t suffer from yellowing. Yellowing happens with the UV from fluorescent lights. Try it on the new CFL bulbs, it will quickly yellow light colored plastics. Then consider what CFLs are doing to your skin.
I once asked the butcher why they did this.
He said: "Fluorescents turn the meat grey. Makes the ham unappealing. So we turn them away from the light."
