A lighting system (,) comprises a nonconductive niche (,) that is free of ground connections and bond connections, and a lighting fixture (,) having no conductive components, except for a current-carrying circuit (,). Snap fasteners (,) secure the lighting fixture to the niche, and lamp sockets are arranged to radiate multiple light beams from halogen lamps in different directions. An electronic isolation transformer (,), which supplies a two-wire, ungrounded source of power to the halogen lamps, presents a linear load and a conduction path to a dimmer switch, and inhibits switching in the electronic isolation transformer when an AC signal (,) applied to the electronic isolation transformer is within a predetermined range. A nonconductive junction box (,) houses the electronic isolation transformer and physically isolates a high-voltage, low-frequency power source (,) from the low-voltage, high-frequency power source in the junction box.

Lighting system, apparatus, and method

In a pool lighting system, each illuminator (10) comprises a color wheel 26, a driver mechanism (24) for rotating the color wheel, and a synchronization circuit (42). The synchronization circuit is responsive to an alternating-current source of power applied to the illuminator to control the driver mechanism to place the color wheel at a predetermined position after a predetermined time subsequent to the alternating-current source of power being initially applied to the illuminator.
