I worked in an animal lab on masters research that required strict 12/12 light cycles. 12 hours bright white, 12 hours red light (circadian rhythms impacted the study design). No windows and no support from post doc or supervisors (both had different serious health problems). I'm quite an upbeat person so it was fine short term, it did put me off academia and purusing a PhD though. Good decision in retrospect and after staying in contact with my peers who have not learned much new and have in my opinion over-specialised.
