It's the end of Perpetual Noon as Cree introduces new LED office lighting fixture

In Perpetual Noon: Fluorescent Lighting and the Modern Office, Margaret Maile writes about lighting design in offices of the sixties: Far from being perceived as a necessary evil, the artificial environment of the mid-century corporate office was praised and celebrated for its stability. Things have changed since then; we no longer design luminous ceilings with wall to wall fluorescents. Architects try to give people a bit of natural light. Suspended ceilings are no longer universal as designers aim for higher ceilings. And most importantly, fluorescent bulbs are being replaced by LEDs.
