Dimming a 9v DC lamp [newbie]

Any ideas for how I can dim and brighten a 9v DC lamp (actually a
strip of CoolNeon)?
It requires too much power for the Stamp to drive, so I have a
separate power source.
I'd rather not buy another pre-built dimming device to control it...
if there is a smart way to do it with off-the-shelf components that
I can string together, that'd be best.

module, according to their website. Do you know what kind of
voltage/current is required? ...Steady or pulsing, etc.?
Do you need variable dimming, or could you settle for a couple discrete
steps, like on/dim/off? (The latter would be easier/cheaper.)

varying the voltage into it.
A series of steps like you say (the more the merrier) would be a
good trade off. If you know a way....
