I built this driver just over a year ago, now bringing it back to life as I got more batteries to power her up to about 400 watts! (36v at 10A - 12A) The arc strikes at 3cm and can be stretched over 12cm.
Just after the arc burnt a hole into a lightbulb, they was a stream of plasma 'shooting' out of the bulb, like a flame thrower. This is because when the arc got inside the bulb, the gas inside heats up, causing it to expand and escaping through the hole thus creating a "plasma thrower".
If you are going to arc a lightbulb, be careful as glass tends to break from extreme temperature change - one time I had a lightbulb that literally blew up, it is cool but dangerous, so wear goggles. :)
