That's because the "light output" reflected back from a newspaper, paper book, or conventional eInk screen, in typical real-life scenarios, "is not even close" to that of a backlit device.

Please quote where in the study they wrote that it is "intended to investigate the effect of different light spectra on circadian rhythm"? I missed that. However, previous research footnoted does show there is such an effect.

For those coming in in the middle, here is the study:

I like it.
