The voltage regulator 3006 includes circuitry that receives rectified voltage, V1 at an input, and downconverts this to a regulated or bus voltage, V3, at an output. Typically, the bus voltage, V3, is equal to or greater than an LED voltage, VLED—is sufficient to keep the one or more LEDs lit. VLED is specific to each set of LEDs, but 12V, 24V, and 50 are some common LED voltages. The voltage regulator 3006 can also generate a low voltage, V4, and provide for powering the first the controller 3010. The voltage regulator 3006 can adjust the bus voltage, V3, as dictated by control signals from the first controller 3010. The voltage regulator 3006 can include circuitry or control to enable power factor correction (PFC). In some embodiments, the voltage regulator 3006 may include a switch-mode power supply. In some embodiments, the voltage regulator 3006 may include one or more switches, and a duty cycle of these switches, as controlled by instructions or signals from the controller 3010, govern the bus voltage, V3. Embodiments of details of the voltage regulator 3006 can be seen and are described relative to
