Abstract
Lighting fixtures and lighting systems for use in areas with high magnetic fields or areas that require low EMI emissions. The lighting systems include a non-ferrous lighting fixture having an LED light source and a control circuit. The LED light source includes one or more LEDs, and the control circuit provides a regulated operational current to the LED light source. The control circuit includes at least one switch for controlling the flow of current through the control circuit. The switch has a first state and a second state, and the operational current provided to the LED light source is increased and decreased in a linear manner based on the state of the at least one switch.
