An electrically-powered device designed to emit red light for phototherapy primarily to accelerate healing of cutaneous/mucosal wounds, treat mild skin disorders (e.g., mild acne), intraoral or nasal conditions, and/or treat musculoskeletal symptoms (e.g., pain, spasm, stiffness) through modification of cellular metabolism and/or improvement of blood flow. It may have various designs (e.g., hand-held, arched bar, flexible pad for adapting to body areas) and is intended for use in the home and clinical settings.
