A low current loss ballast operates a high intensity discharge lamp with or without radioactive krypton. The ARL includes a reference to audio data, an audio command,and an audio server reference that identifies an audio server computer system that can process the reference to audio data within the ARL according to the audio command within the ARL to producing output, which may be audio or another type of output. The actuator has a motor control system that limits the stroke velocity for both the extension and retraction strokes, including a damper feature capable of effectively braking the actuator during the back-driven extension stroke.
