The same temp as the toaster .
Its cooling its self as photons take sme thermal energy out with the
photon ..
Its not as hot as it looks , the toaster pole and light filiment
poles are the same stuff ..
You cant get hot enouph to melt that post .,,or they come apart..
Droped the toaster filiment inside the light bulb
and turned up the volts..not enouph photons are leaving it so not enouph
heat is CONVERTED at the square of its resistace.

Somewhere between 1800 and 2700 K. YMMV.
