Independent lighting control

A lighting control system comprising:

• a first light source;
• a second light source;
• a driver circuit configured to independently drive the first light source and the second light source;
• and
• a sensing circuit configured to:
• sense a characteristic of the driver circuit,
• connect the first light source to the driver circuit when the characteristic of the driver circuit is less than a threshold, and
• connect the second light source to the driver circuit when the characteristic of the driver circuit is greater than or equal to the threshold.

A lighting control system comprising:

• an input capable of being driven in a first polarity and a second polarity reversed from the first polarity;
• a first light source connected to the input and configured to generate light when driven at the first polarity;
• a second light source connected in anti-series to the first light source and configured to generate light when driven at the second polarity;
• a steering bridge connected to the input and configured to independently drive the first light source and the second light source;
• a sensing circuit configured to sense a characteristic of the input;
• and
• a controller connected to the steering bridge and the input, the controller configured to:
• control, via the steering bridge, the polarity of the input,
• receive, via the sensing circuit, a signal indicative of the characteristic of the input,
• connect the first light source to the input when the characteristic of the input is less than a threshold, and
• connect the second light source to the input when the characteristic of the input is greater than or equal to the threshold.
