I freely admit that the biological & medical sciences are my weakest area of scientific understanding, so I may be missing something obvious, but it does seem to me that this research is fundamentally broken, as opposed to being just a first step.
If the research is intended to investigate the effect of different light spectra on circadian rhythm, why conceal any such effect under such dramatically different light levels? Why introduce fundamentally different physical comfort arrangements between the test cases?

The news media are overstating far more than the scientists.

In this case, at least as far as the BBC report is concerned, I'd say the main problem with the reporting is the failure to critically question the research. In terms of the actual claims, the BBC doesn't seem to be overstating it all that much more than the scientists.
