Re: Why do the colors get more intense when looking at an incandescent bulb?

A hot, glowing object obeys two fundamental radiation laws.
Wein's Law and the Stefan-Boltzman Law.
The S-B law relates the energy emitted by a radiating
body through the equation E = (sigma) T^4, where E is the energy flux
and T the temperature and sigma is the S-B constant.

When you increase the temperature (i.e. increase the voltage on a light)
the amount of radiation emitted goes up as the fourth power of temperature,
so the intensity increases greatly making the colors more brilliant.
An object at 2000 Kelvin puts out 16X more radiation than one at 1000
Kelvin.
Wein's Law relates the wavelength of maximum intensity as a function of
temperature.  When you observe the increased brilliance of the colors
does the peak brightness shift from red to red-orange to yellow?
It should.
