thats a 40 watt bulb. I tried a 30 watt one buy a different manufacturer and
got nothing until I let it arc through the glass and onto the filament. I
did notice something...once the bulb becomes ionized(the 40 watt one)I can
move it quite far(holding it in my hand as a ground)away and the glow will
remain I'm guessing because it takes less current to keep it going. Also, I
drove 3 of those bulbs with this thing and it helped with glass heating a
bit and produces a hell of a more impressive display. I will try and get one
of those big spherical bulbs and experiment with that.
