Ah yes, of course. You have to go out of your way to get it to full brightness in the first place. Even the default auto-dim, not even going to night mode would be preferable. The way it was setup, I am surprised the test subjects even struggled through the 4 hours of reading. Sure, the eyes will adapt after a while - but reading freewilly hours at a time? I don't think so.
If all they were interested in the study is different peaks (420 vs 620) in light, they could have done so with paper books and different spectrum lamps. If you look, the lightoutput LEereader vs paper is not even close.
