I have phased out all halogen and filament bulbs around the house and are all replaced by LED ones, especially now we can get the 60 watts to 100 watts equivalence as well as dimmable ones. However, I did it over a period of a few months what with bulbs costing around £4 a piece and I have more light fittings than Blackpool Illuminations.
What I have done was to scatter lamps around the room, especially the living room and my hobby room (have four lamps in the latter room) which seem to give a better wash of light as well as making the room that more warm and inviting, I still have "the big" ceiling light but used only to pop into the room to get something.
While my house is somewhat future proofed for now since LED light bulbs have come a long some way in terms of brightness but the one thing I do notice is the 50 hz flickering when I move things around quickly, feels like we have gone back to the days of staring at an old fashioned CRT telly.
