The artificial wick may be in the shape of a wick or flame and may include a light source. One or more light sources may be configured as the artificial wick. The light intensity, color and rate of change of light may be modulated to produce a more realistic looking artificial flame. A standing wave tube may vary the rate of mist exiting one or more enclosure openings in the tube enclosure.
