The repaired bulb didn't last very long. It's not an outright failure, but looks like a heat issue. After a while the base heats up and seems to go into a protective thermal shutdown. Then it cools down and the light starts up again. It's a slow cycle, but still annoying. I've pulled the bulb again and replaced it with a Sylvania-branded CFL.
Yesterday the warranty replacement LED bulbs arrived. I decided that the office needs more light than they provide. The office is now all-CFL again and looks the better for it.
One LED bulb is in a desk lamp that had been sitting all but unused for some time. That's where the Sylvania CFL came from. I put the lamp in the living room at the end of the couch where it makes a reasonable reading lamp. Since it uses so little power, I won't feel too guilty about not turning it off should I decide to take a nap and not feel like getting up turn off the light.
The other is near the back door and lights up the small area joining the kitchen, downstairs restroom, and laundry area well enough. But it also revealed that I need to change the switch (hopefully just the switch!) for that light: Off isn't really fully off. The bulb still glows, if dimly, when the switch is off.
