Biomedical Results of Apollo, SP-368, p. 133. All temperatures were measured at the heat exchanger inlet. During the Apollo 13 mission, the LM environmental control system provided a habitable environment for about  83 hours (57:45 to 141:05 GET). Cabin temperature remained low due to low electrical power levels. This caused crew discomfort during much of this period, with cabin temperatures ranging between 49F and 55 F.

* Further examination of Biomedical Results of Apollo reveals that actual cabin temperatures dropped to a low of 43F. It is likely that the figure in the original text refers to the low cabin temperature while the Command Module was powered up.
