I tipped a 300 watt tungsten halogen "torchiere" lamp (cheap at the mall)
over on its side to illuminate the top .. the instantaneous lamp temperature
varied. My 1/10,000 second shutter speed reveals clearly the appreciable
variation in the tungsten filament temperature. Even this incandescent source
has a small stroboscopic effect, something that was certainly a big surprise
to me. The effect would be greater for a tungsten halogen lamp than it would
be for a conventional nitrogen filled bulb because the peak temperature of
the former is greater, and it cools faster.
