They won't though. Where's the market once we've all got enough to fit everything?
 
CFL's a built to last 10 years and burn out in one...
 
+Patty Rose 3 hrs could be normal if you see it as the average time per day spread out over a year.

Here in the summer time (in Denmark) it doesn't get dark before 10 to 11 pm and around 5 pm in the winter.

So here an average of 3 hrs would be normal I guess. Also there's the days when you are not at home (vacation, business trips etc)
 
wouldnt it have to take 23 years for them to come up with that number?
 
I did the math on this, combining the energy savings and replacement cost. Incandescent was the most expensive over 50 years by a huge margin. CFL was cheaper due to current prices. If the LED prices come down like every other solid state device in a few years it will look silly to use anything else. The unaccounted costs of creation and disposal are lower with LED's since they aren't toxic waste. They light up instantly, and can have a nice color temperature (and can change color). They work with dimmers. They really are the future of lighting.
A caution though, don't mix led and incandescent or CFL in the same fixture. It tends to kill the led.
