Better than florescents

List,

For checking the sync of synchronous RSG motors, if you don't have a
synchronized strobe light, then use neon lamps instead of florescent for a
clearer view of your marked disk.  Neon night lights, decorative "candle"
lamps, etc. are available.  They are dim, so you will have to shut off most
of the light to see the spinning disk.  Neon lamps turn on and off much
faster than florescents do, making a clearer pattern.

I  use 10 1/4 watt neons in series powered by an ignition coil driven by a
pulse generator to calibrate my async RSG.  A flash tube would be much
brighter.
