    Abstract: A lighting driver includes a processor configured to generate a compensator signal based on a first signal during a constant current mode and based on a second signal during a constant voltage mode. The first signal corresponds to a current through an LED light source coupled to an output of the driver, and the second signal corresponds to a voltage at the output. The driver further includes a controller to control, based on the compensator signal, an amount of power provided to the LED light source. The driver also includes a constant current source circuit to be coupled to the LED light source. During the constant current mode, a flow of the current through the constant current source circuit is disabled, and, during the constant voltage mode, disabling the flow of the current through the constant current source circuit disables a flow of the current through the LED light source.

    Abstract: A connector installation tool can include an inner surface having a first portion having a first perimeter, where the inner surface forms a cavity that traverses a first length of the inner surface. The connector installation tool can also include an opening having a width and traversing a second length of the outer surface and the first length of the inner surface. The connector installation tool can further include a front face located adjacent to and substantially perpendicular to the first portion of the inner surface. The connector installation tool can also include a rear face located adjacent to a distal end of the inner surface, where the rear face is substantially parallel to the front face.
