Sun?

MM463, sun as a back drop – what sun?
 
Fair does, “use a bare light bulb” if no sun.  What a search to find an old fashion filament light bulb, or anything suitable.  My biggest surprise was the amount of heat it threw off, I could feel it from a  mtr or two back.  All that energy we used to waist.
 
Of course I had to do the obligatory ‘filament’ shot which is here on Flickr.
 
Many thanks to Carolina for setting the interesting challenge.
