Did you do well in math? Can you explain how a 500 watt tungsten bulb can deliver the same light as a 500ws flash delivering light in 1/175th sec?
Take one second and divide by 175 = and multiply the result by a big enough number to equal 500. Got it? That’s how many tungsten watts equal a 500 ws studio strobe.

it seems to me that a 500 watt tungsten lamp exposed for 1
second should give the same amount of light to the sensor/film
as a single 500ws flash exposure.

I think that something vexing is the fact that the electronic flash delivers its light over a short time while tungsten lamps can (or do) deliver it over a long time. If one compares them at the assumed duration of the flash then the tungsten bulb will come out the weaker of the two by far. But if you compare them during an exposure time of a second or a minute or more then the tungsten lamp wins. It seems to me anyway.
