Plasma disc voltage?


I've seen a few of these plasma discs and was wondering if anyone know what voltage these things generate? I know its some high-frequency ac voltage powering the disc, but does anyone have a rough estimate? Just curious. I've been meaning to take one apart, but I don't think my multimeter could withstand a  shock from it. (Rated for 600v).

Well, since you're the only answer, you get best answer! Also, through experimentation I found it to be around 2-3 kV.
