Have we filled our workplaces with photonic deathray diodes?

Have we turned our homes into caves? Maybe a little.

Scott Zimmerman is an engineer who partners with health researchers and other scientists to model the effects near-infrared light not just on the eye, but skin, blood vessels and the brain and he’s concerned about how the observed good effects NIR are being set aside as we convert the built environment to LED lighting with IR films over the windows. We may be trading efficiency for our well-being. His solution: a hybrid LED-incandescent lamp that comes with a few other surprise benefits on the design side.
