Abstract

An apparatus includes a lamp-control circuit. The lamp-control circuit is configured to be electrically connectable to an electrical source having an output voltage that forms a periodic wave formation. The lamp-control circuit is also configured to be electrically connectable to a lamp array. This is done in such a way that electrical current, in use, flows from the electrical source to, and through, the lamp array. The lamp array includes lamp segments. The lamp-control circuit is also configured to urge each lamp segment of the lamp array to consume relatively constant power for a portion of a cycle of the output voltage of the electrical source in such a way that said each lamp segment of the lamp array, in use, emits a relatively constant light output for the portion the cycle of the output voltage of the electrical source.
