Abstract

A lighting system includes a base unit and a first modular light. The first modular light includes a first light unit, and a first lighting technology module. The first light unit includes a first light element that emits light, and a first mechanical, electrical, and control signal physical light unit interface that is removably coupled to a first mating light unit interface on the base unit. The first lighting technology module is physically separate from the first light unit and includes a first light driver that drives the first light element, a first light engine that is coupled to the first light driver, and a first mechanical, electrical, and control signal physical light technology module interface that is removably coupled to a first mating light technology module interface on the base unit.
