You're wrong. The very word "incandescent" means "glowing because it's hot". The fillamant and the gas inside the bulb reach temperatures of up to around 3000 K

You're wrong. The very word "incandescent" means "glowing because it's hot". The fillamant and the gas inside the bulb reach temperatures of up to around 3000 K. The surface of the sun might be about 6000 K, but it glows white-hot, not yellow as many believe.
