30 Claims

1. Apparatus for lighting, the apparatus comprising:

a section that:

is configured to extend from a first end that is configured to be electrically disconnected from a neighboring section by mechanical disconnection to a second end that is configured to be electrically disconnected from another neighboring section by mechanical disconnection; and

includes a light emitting diode (“LED”) module circuit including:

a first LED having a first color correlated temperature (“CCT”);

a second LED having a second CCT; and

a support connecting the first end and the second end, the support including:

a first output pole that traverses from the first end to the second end; and

a second output pole that:

traverses from the first end to the second end; and

is electrically isolated from the first output pole;

a selector configured to select from mixed CCT states a mixed CCT; and

a controller circuit configured to:

for a first fraction of time, apply to the first output pole and the second output pole a voltage having a first polarity; and,

for a second fraction of time, apply to the first output pole and the second output pole a voltage having a second polarity that is opposite the first polarity; wherein the first fraction of time corresponds to the mixed CCT.
