Hi, my friends were trying to theorize a way to create a "light bulb" that 
does not emit light but rather creates an area effect of darkness that 
possibly lightens towards the edge. We thought that to do this the "filament" 
would not emit visible light and heat but rather some sort of particle that 
would absorb the photons of visible light spectrum and perhaps infrared as 
well so it may also create an area of coolness as well. 

So is there someway to create a "dark" bulb that gives the opposite effect of 
a light bulb?
