1. A lighting system comprising:
a plurality of lighting devices each comprising a light source and a light source holder configured to disburse light from the light source;
a plurality of power devices each operable to power one of the plurality of lighting devices, the plurality of power devices comprising a first power device and a second power device, the first power device comprising a first plurality of electrical contacts, the second power device comprising a second plurality of electrical contacts, the first plurality of electrical contacts, being spaced from each other substantially the same distance as the second plurality of electrical contacts; and
a group charging platform operable to concurrently charge the plurality of power devices, the group charging platform comprising a surface formed by a plurality of charging tiles, the first plurality of electrical contacts disposed on an outer portion of the first power device such that, when the first power device is placed on the charging platform, the first plurality of electrical contacts is operable to electrically couple to the plurality of charging tiles, thereby forming a first conductive path from the group charging platform to the first power device, the second plurality of electrical contacts disposed on an outer portion of the second power device such that, when the second power device is placed on the charging platform, the second plurality of electrical contacts is operable to electrically couple to the plurality of charging tiles, thereby forming a second conductive path from the group charging platform to the second power device, wherein
each of the plurality of charging tiles has a width approximately equal to a distance between the first plurality of electrical contacts; and
the plurality of charging tiles having either a positive polarity or a negative polarity and are arranged in a checkerboard pattern wherein polarity alternates in a first direction and a second direction; and
the plurality of power devices, when coupled to the group charging platform for concurrent charging, are decoupled from the plurality of lighting devices.
