I only see one potential problem: The inverter for the LEC panel
produces 220VAC at 1150Hz. Right smack in prime audio territory. From
what I recall, EL panels operate at a higher frequency than this.
Someone should tell these guys that they really need to keep the
excitation frequency out of the audio range (if possible).
