Also to interject, you can see the "dot effect" with your naked eyes.
Just look at distant mercury or sodium vapor lamps and roll your eyes.
You'll see them as dots.

   proof

Initially, I was sure that a gas-discharge street lamp bulb had too much 
thermal mass to create the distinct dots of light seen in the "traces". I 
just did not believe that the red-hot inner quartz tube used in most of 
these lamps could cool enough between AC cycles to create the dot effect.

Accordingly, to obtain my "own" proof, I found a location where I could 
"pan" my digital camera and capture both a gas-discharge street lamp and a 
conventional incandescent lamp in the same frame.

The results are extremely clear; the gas-discharge street lamp created the 
string-of-dots effect, the incandescent lamp left an uninterrupted solid 
line. Apparently, the pulsing plasma is much brighter than any hot glowing 
parts of the bulb.

If Chip can post the image somewhere, it should convince even the most 
skeptical.

Scott Hanson
