To properly sync this flash bulb unit you would need a camera with an "M" (flash bulb) sync mode. Modern digital SLRs are only designed for "X" (electronic flash) sync.
The only way to use the Alpex would be in a completely darkened environment to set the camera to a very long time exposure (or bulb) and then manually set off the flash bulb, independent of the camera.
This technique does work in caves and nighttime outdoor photography including some "painting with light" techniques.
I would not try to attach the flash unit directly to the Canon camera because the surge current necessary to set off the flash bulb is waay more than the camera is designed for. You could cause serious and expensive damage to the camera trying to trip the flash bulb.
An older film camera with an "M" sync setting should be safe for a trigger for the flash bulb unit.

Where would you buy the bulbs for it, if it would work?
I think I would suggest a real, modern electronic flash as a safer, and preferable portable lighting solution.
Love your gallery!

BTW, what battery type does that unit require?
