Flash a fluorescent tube
Well, first of all, you need to have electrodes hot all the time.
If you will try to heat them at the moment of pulse you will kill your tubes in a matter of hours.

Then you can turn on your main constant-current (ballast circuit) power supply for whatever time you need as long as it's fast enough to stabilize during your 1-10-100ms pulses. 

You can use 1 constant-current device for multiple lamps if you connect then in series, but the required voltage will be much higher, so I believe it's cheaper to have 1 device per lamp.
