When havels sylvania became feilo sylvania, how did that effect their lamp manufacturing? I was thinking about buying a box of 18w 835 lamps since philips and osram had allready dropped 3500k fluorescent lamp (well philips did still offer them in longer lenghts) feilo sylvania still seems to have them listed in 18w. Does someone know if those are still manufactured in germany?

So far no real changes in the LFL manufacturing, they are still produced at Erlangen, Germany.  Several other factories have or are about to be closed though, including the HID / LED / fixtures plant in Belgium :-(

And what happens then ? I'd expect that the 2017-requirements lamps remain available for many more years
