Let there be light

Its one am and I cant get to sleep , been taking pics of random things, this is a close up of a 100 watt tungsten filament it burns at around 3000 degrees C. I used a nd filter as it was so bright ,I dont think you can buy these any more as they have been phased out , not surprising as only 5 percent of the energy they use is turned into visable light .now lets try to get back to sleep :)
