    Abstract: A light fixture includes a housing that defines a first cavity. Further, the light fixture includes a light module that is disposed in the first cavity and is configured to emit light in a first direction. Furthermore, the light fixture includes a light redistribution apparatus that is coupled to the housing and is disposed in the first cavity to receive the light from the light module. The light redistribution apparatus includes an outer collar comprising a body that defines a second cavity. Further, the light redistribution apparatus includes a plurality of redirection segments that are disposed within the outer collar and across at least a portion of the second cavity such that they redirect a portion of the light that is emitted in the first direction towards a second direction and allow a remainder portion of the light to travel unobstructed towards the first direction.

    Abstract: An electrical circuit can include a power supply that provides primary power, and an electrical load coupled to the power supply. The electrical circuit can also include an energy storage unit coupled to the power supply and the electrical load. The energy storage unit can include at least one energy storage device that stores reserve power using the primary power, and a first switch disposed between the power supply and the at least one energy storage device. The energy storage unit can also include a controller that operates the first switch from a closed position to an open position after a first amount of time. The at least one energy storage device can receive the primary power when the first switch is in the closed position. The at least one energy storage device can fail to receive the primary power when the first switch is in the open position.
