'Bayonett' is a different thing, so I presume you mean the regular Edison type E27 screw socket bulbs.
That is an EU wide ban. You may find some old stock somewhere, but new ones of that power aren't being imported or manufactured in Europe anymore.
Curiously, this ban doesn't include halogen bulbs. E27 socketed halogen bulbs have become available recently, they have the similar bulb shaped glass envelope. Those would be a drop in replacement, however they are still more expensive and probably have a shorter life as well. I'm not sure if you can get them in 100W size though.
