The old fashioned incandescent light bulb produces yellowish colored light by heating tungsten to a very high temperature and the tungsten radiates light peaking in the yellowish-white range

If you wanted a more blue light that was brighter, what would you need to do with a simple filament light bulb?
A) You would have to make the filament thicker and add more current to make it glow brighter (for example, a 75w vs 40w bulb).
B) You would have to add a layer of some other material that would absorb the longer wavelengths of light.
C) You would have to add more electrical current to raise the filament to a higher temperature, which would make it burn out faster.
D) You couldn't do this; it isn't possible.
