I have an AE500, and would like to power it via my UPS, so that if the mains ever fails where I am, I hopefully don't have to buy a new bulb. The UPS has a connector cable for linking to a PC, ie. male to female IEC style plug. The AE500 uses some roughly the same layout as an IEC plug, but has odd round pins on the connector. Does anyone know where I can find a male IEC to female Panasonic odd power connector cable?
