1. An apparatus of a light engine, the apparatus comprising:
a core; and
a flexible printed circuit board comprising:
a flexible body disposed on the core and having sets of light emitting diodes (LEDs) mounted thereto to at least partially encircle the core, each set of LEDs disposed at substantially a same distance from a center of the core as each other set of LEDs, and
flexible legs extending from the flexible body such that the flexible legs, flexible body, and core pass through a plane substantially perpendicular to a direction of extension of the flexible legs from the flexible body, a terminal portion of at least one of the flexible legs configured to receive control signals to control at least some of the LEDs.
