I have one nearly the same, Peter, even the 239 Watt rating. Now how could you ensure it draws 239 watts!

Really, with the generator regulator hunting up and down as the field is turned on and off. It is like those Duro-Test 101 watt traffic signal lamps....

A bureaucrat chose this rating, not an engineer!

Yep, gets as hot as hell dissipating 250w through a bulb the size of a tennis ball, that's why if it id burned cap up, the glue/capping cement will "let-go" and the bulb could fall from the cap, (assuming the solder holding the lead ins melts too).

These are filled with argon, which is a relatively good conductor of heat, poorer than air, but a lot better than krypton or xenon.
This would run in the 2750-2850K region, a little higher than a standard lamp, but not so much so that the life is drastically reduced. As a low voltage lamp with a short-thick filament its efficacy would be considerably more than a high voltage one with the same power rating and a long, thin filament with lots of supports to maintain it at the focal point.
