The purpose of this study is to examine, in healthy controls, whether LED lighting that has a color spectrum similar to that of sunlight is able to differentially impact mood, circadian rhythms, sleep, and behavior, as compared to standard fluorescent lighting.

| LED - Sunlike | Experimental | Device: Light | LED lighting with spectral pattern similar to that of sunlight |
| Fluorescent | Active comparator | Device: Light | Fluorescent light at same illuminance (lux) as LED light |
| Dim | Placebo comparator | Device: Light | Dim fluorescent light with same spectrum as "Fluorescent" condition |
| LED | Active comparator | Device: Light | Standard LED lighting |
