I had the idea of this image since a while.
The settings for the bulb picture you can read below.
strobist info (for the person):
580EX II with softbox infront of me in high position, manual mode 1/2
430EX left and right sidewards behind me, manual mode 1/4
Silver reflector infront of me the lit up the shadows a bit.
Triggered by the 580EX II.
The composition is done in ps. I added another background.
