Abstract
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.
