Abstract
A lamp includes an enclosure with partitions defining a channel having channel segments and/or providing multiple paths for an electrical arc to travel. The channel segments can be implemented by adding additional electrodes in the channel formed by the partitions, by forming a channel where the arc may travel in multiple directions, or by a combination of these methods. The channel segments and multiple directions of arc travel tend to reduce the voltage required to start the lamp.
