Penko; why do you believe that CC themselves decide when and how much to dim the lights?
In addition, what makes you think that at night, CC prefer their pax wide awake, walking around and wanting food and drinks rather than peacefully asleep?
I mean really......
Most airlines have procedures for most things, including cabin lights.
And as long as these procedures are in accordance with the aviation authority rules governing that particular airline, the airline decides how much light at what stage of the flight. The CC follow those instructions.
multi_engined, as far as I know, there has been done a far bit of research on the subject, but the studies are inconclusive as to what, overall, is the best policy.
ei-flyer, the 737, like most aircraft currently in use, has various cabin light options. Again, up to the airline as to what they deem the best procedure, and for the CC to carry out their airline´s procedure.
In your case, before your next night flight, take yourself online and buy a version of:
Good luck.
