Indeed, and not only that, but the element rating is only however much of it you're using. A 300W resistor tapped at 10% won't handle anywhere near 300W! ;D

With a light bulb bank, you can also play with different response times.
The thermal mass of a 100 watt filament is larger than that of a 25 watt filament. Putting four 25 watt bulbs in parallel will yield a faster current limiting times.
Several years ago, while using my very first digital scope I captured some waveforms and "saved" them by taking a photo...on a film camera.
I can't find the photos anymore, but if I recall correctly the 25 watt filament would fully limit the inrush within the first cycle, 16.6 msec.

Bulb is good, it is a live heart beat indicator too. Only issue now is it is getting harder to get one.
