Abstract:
A lighting system suitable for chromatherapy (10) includes a plurality of light fixtures (12) mounted through walls of a tub basin (16) to project different color light into the water in the tub. The light fixtures (12) are operated by a central control unit (22) and each includes a housing having a concave internal surface. An array of light emitting diodes (78) that project different color light is mounted under a cap (48) covering one end of the housing.
