That's a very interesting idea. I didn't realize the wattage was so low. I'll bet there are some short wavelength UV coming from that, so do be careful please. I'd think if a normal balast has enough of a "kick" to get the gas lit up, it would probably work. Again be careful with high voltages and if there is a big balast transformer, exercise caution because the HV winding could have enough inductance to hold a big charge.
