The study is worth reading. The light exposure was for 12 hours/day, they showed steadily increasing mortality with increasing photon flux density of blue, and they showed that white light exposure with blue filtered out (at the same intensities) did not have the same effect.

They also did not test increasing photon flux density of white/filtered light. They only bothered controlling for PFD after introducing filtered light.
Sounds like experimental protocol was invented … on the fly.

Also, white light with the blue filtered out is not an appropriate control condition. What's to say the blue light flies didn't just deteriorate normally and the artificially filtered white light had a positive health effect for the control group?
