[time-nuts] Conducting Bench Top Material

[Ed Palmer]

The most important thing to remember about CFLs is *don't* use them 
anywhere that they will be turned on and off a lot (e.g. bathrooms).  
Use them where they'll be turned on and left on.  Short on / off cycles 
can reduce their lifetime to 15% of normal.  Here's a report on the 
subject:

(I have "standard" bulbs that have outlasted multiple CF bulbs in similar applications) In particular, I have a 75W desk lamp bulb which has been in use since '97 and gets more hours than the ceiling CFs in the same room, which have been replaced at least 3 times...
