As i recall, the original sleep cycle studies attempting to identify an underlying circadian rhythm required heroic experimental control to exclude any 24hr cycle driving stimuli. Since I doubt that the Chilean situation came anyplace close to eliminating these cues (I assume they had watches), I'd doubt that there would have been significant drift even without the special lights (though they probably helped).
