That is the problem. You need new fixtures. You can't keep the old
Edison or whatever fixtures from incandescent bulps. So the LED bulps
will be inherently incompatible with existing incandescent bulp
instalations. This incompatiblility is the problem.

Fixtures for incandescent bulps try to isolate heat as good as possible
because incandescent bulps work better the hotter they are. But LEDs
need to be cooled quite well. So puting a (high power) LED in a fixture
for incandescent bulps is complete nonsense.
