A lighting fixture has a lamp and a housing for a lamp ballast. In the new fixture for providing bilevel illumination, the housing also contains a control device comprised of a dual capacitor and a 'random crossing' relay connected to the capacitor. A single electrical control wire is attached to the relay and extends from the housing to a control module for remotely controlling the level of illumination consumed by the fixture. In a system employing one or more of the new fixtures, the level of illumination provided by each fixture is controlled by applying a signal to the control wire and switching the relay independently of the instantaneous value of the voltage across the relay terminals. A new method for providing two levels of power to the fixtures (and, thus, two levels of illumination) is also disclosed.
