Scaling Down Compact Flourescent Bulbs

Burgess portable fluo light that's from the '60s...
- remember those batteries? )

Ah, Safari lights. Takes me back to camping as a Scout
....the days when high-voltage batteries were considered normal
and inverters were exotic.

Yeah, I'm pretty sure that's the name of it. It's stuck away out in
the garage somewhere. One would think that using a simple vibrator
inverter from the 1930s would be cheaper than high voltage batteries.
A ham friend and I were making 250W inverters back in the '60s using
Ge power transistors so it could've been done easily with a single
power transistor.

Back in High School, I made an invertor using a single transistor,
single winding oscillator, using a power transformers from old
transistor radios. The inverters were used to power xenon strobe
lights (stroble tubes taken from a disposeable camera or something,
the trigger transformer was a few turns of#36 magnet wire on an old IF
coil from an old tube radio set).
