Lighting strips with multiple isolated power buses

A method to power a lighting strip, the method comprising:

• providing first power to a first power bus of a lighting strip, the lighting strip having a plurality of sections separated by cutlines, the first power limited to no more than 100 W and no more than 60 V;
• providing second power to a second power bus of the lighting strip, the second power bus electrically isolated from the first power bus, the second power limited to no more than 100 W and no more than 60 V;
• powering a first lighting device in a first section of the plurality of sections of the lighting strip from the first power bus;
• powering a second lighting device in the first section of the lighting strip from the second power bus;
• powering a third lighting device in a second section of the plurality of sections of the lighting strip from the first power bus;
• and
• powering a fourth lighting device in the second section of the lighting strip from the second power bus.

A lighting system comprising:

• a flexible, elongated printed circuit board (PCB) having a width that is perpendicular to a length of the PCB, the PCB divided into a plurality of sections by cutlines extending across the width of the PCB;
• a first anode conductor and a first cathode conductor, affixed to the PCB, extending along the length of the PCB, passing through the plurality of sections, and crossing the cutlines;
• a second anode conductor and a second cathode conductor, both electrically isolated from the first anode conductor and the first cathode conductor, affixed to the PCB, extending along the length of the PCB, passing through the plurality of sections, and crossing the cutlines;
• each section of the plurality of sections comprising:
• a first lighting device affixed to the PCB and electrically coupled between the first anode conductor and the first cathode conductor;
• and
• a second lighting device affixed to the PCB and electrically coupled between the second anode conductor and the second cathode conductor.
