The trouble with LEDs is that they don’t come in high enough lumens to replace the CFLs we have in fixtures with only one bulb (and finding bright enough CFLs was a problem in itself.
In fact, I spent a lot of time looking for a new floor lamp for the living room and ended up replacing the glass diffuser bowl (on the existing lamp) with home-made support for the shade that was big enough for a sufficiently bright CFL, and then remade the lampshade frame to make it taller to fit over the harp properly. And, of course, re-covered the lampshade.
