Neon Tube Light, how to illuminate

HI there,

I've created a Flourescent Tube light and I'm having a hell of a time to get it to illuminate properly.

I applied a White Neon Tube appearence to the tube set a Luminous intensity of 2 w/srm2 to it and when I render I get nothing.

I have put point lights inside the tube but to no affect.  Any ideas?

regards
