The finial is coupled with the wiring extending out the opening in the end of trunk support to maintain electrical continuity with the light source assembly.

A lighting device has a power interface and a control circuit in communication with a program and the LEDs to simulate a flame. The program determines a first group of LED control integers to simulate a perpetual middle with a perpetual middle center and a perpetual middle range within which one or more of the LEDs are to be at least partially actuated. At least one LED is actuated based on the first group of LED control integers. A first target for simulating movement of the perpetual middle center toward the first target and a first acceleration value is defined.
