26. CFLs do not work well everywhere
So if you're having trouble with them, make sure you're using them in the right place.

There's two common places where they fail to perform well:
1) If they don't run for at least 5 minutes, the ballast breaks much sooner than expected. So they're not a good choice for a bathroom or closet where you only turn the light on briefly.

2) If it's cold. If it's near freezing or colder, the bulb will take a very long time to warm up, and again suffer a premature death.

  - Between the short lifespan, the abysmal light quality, the mercury and the switching power supply  GliderGuider   Jan-19-11 11:22 AM   #3 
  - And that Nuclear electricity you buy is "too cheap to meter!" anyway, right?  Tesha   Jan-19-11 11:54 AM   #14 
  - The problem is that there's more to the life cycle than the electricity.  GliderGuider   Jan-19-11 12:03 PM   #17 
     - So how was the mercury in the CFL affecting you...  Tesha   Jan-19-11 12:25 PM   #25

        - It could be that the duty cycle on mine has been too short  GliderGuider   Jan-19-11 04:05 PM   #48 
           - You have to stop the "turn off the switch" behavior when you leave a room with CFLs.  joshcryer   Jan-19-11 07:24 PM   #58 
  - That's very very odd, I'm going on 4 years for my latest batch. I figure 5 years is reasonable.  joshcryer   Jan-19-11 07:21 PM   #57 
  - I use them, and they last a reasonable amount of time...  InvisibleTouch   Jan-19-11 11:29 AM   #5
