Abstract: An example electric lighting system includes a lighting device that includes a housing including a lighting element and a power device holding portion. The power device holding portion includes a cavity. The cavity includes a first and a second electrical contact disposed within the cavity. The power device includes a third and a fourth electrical contact. The power device includes a coupling component. The coupling component is removably couplable to the power device holding portion such that an electrical communication is established when the power device is inserted into the cavity at any rotational position relative to the lighting device about a shared central axis. The power device is operable to power the lighting device through the electrical communication. The electrical communication is established between the first electrical contact and the third electrical contact and between the second electrical contact and the fourth electrical contact.
