Abstract: Apparatus and systems including one or more first LEDs, each first LED configured to generate first radiation having a first spectrum, and one or more second LEDs, each second LED configured to generate second radiation having a second spectrum different than the first spectrum.

In different aspects, the apparatus/systems may be configured to generate white light and/or multicolor light, may be formed to resemble conventional light bulbs, and may be arranged as a linear chain of nodes.

One or more controllers control at least one of the first radiation and the second radiation so as to control at least a color temperature of visible radiation.
