Abstract
A lighting apparatus is provided that is able to illuminate despite the loss of a primary source of power. In implementation, a controller is provided for determining if a loss of normal power has occurred so that a first source of illumination cannot function. In that case, a second power source is provided to supply energy to a second source of illumination. Further, the first and second sources of illumination may use the same switch such that a users inconvenience is minimized.
