An illumination device (e.g., an electric candle, etc.) generally includes a housing, a light source, and a pendulum supporting the light source. At least a portion of the pendulum is disposed within the housing. A support member is coupled to both the housing and the pendulum, and is configured to support pivotal movement of the pendulum and light source relative to the housing. And, a driving device is coupled to the pendulum, at a location within the housing, and is configured to produce the pivotal movement of the pendulum.
