This trial investigates systematic light exposure in preventing fatigue in prostate cancer patients. Prostate cancer patients receiving radiation therapy may feel tired or worn out, find it harder to concentrate or remember things, or may just not like feel like themselves. Systematic light exposure (with a light box) may prevent side-effects experienced during radiation treatment. This trial may help researchers evaluate whether patients receiving radiation therapy for prostate cancer who are regularly exposed to light from a light box during their treatment will experience reduction of symptoms they may experience during their treatment.

PRIMARY OBJECTIVES:
I. Examine whether bright light compared with dim light prevents cancer-related fatigue (CRF) in prostate cancer patients undergoing radiation therapy (RT).
II. Examine whether bright light compared with dim light improves secondary outcomes (i.e. circadian activity rhythms, sleep quality, depressed mood, and cognitive functioning).
EXPLORATORY OBJECTIVE:
I. Explore whether the effects of bright light on cancer-related fatigue is mediated by circadian activity rhythms.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP I (BRIGHT LIGHT): Patients undergo bright light exposure over 30 minutes for 5 or 8 weeks during radiation therapy.
GROUP II (DIM LIGHT): Patients undergo dim light exposure over 30 minutes for 5 or 8 weeks during radiation therapy.
