Bright White Light
The light will be administered via a Litebook Elite or Litebook Advantage (Litebook®, Ltd., Medicine Hat, Canada). The Litebook® is a small (6×5×1 in.) and lightweight (8 oz.) box and will be fitted with adherence monitors to record at what time and for what duration the light box is turned on. The Litebook® is designed to be placed on a table approximately 18 inches from the participant's head and within 45° of the midline of the visual field. The BWL Litebook® looks identical to the DRL and utilizes 24 white light-emitting diode (LED) lights and does not emit ultraviolet light.
