Anyone ever have a lamp that just won't die?
I bought these CFLs (

I know it only cycles once per day (although it used to come on during the day sometimes before I replaced the PC), and it's a dimmable lamp running at full brightness all the time, maybe that makes the difference.
Also, one of the few incandescent lights in my house is a recessed light. I remember my dad replacing the lamp when I was in grade school about a decade ago, and I remember the box saying "double life", and it's sure lived up to that title.
Also had some very old lamps on a rotary dimmer in a bathroom, which I think extended there life, because they got turned up to full brightness slowly. You could see the filaments sagging a bunch between the supports! I used to set the dimmer as low as it would go and look for "hot spots" along the barely glowing filament.
