I think what a lot of people miss is the savings in electricity costs. You get the light equivalent of a 100 watt bulb for 23 watts with a CFL. With an LED it's even greater. 90% of your electrical cost to light your home with incandescent bulbs goes to produce heat not light. An incandescent bulb is primarily a heater.How much less? They cost 30 times as much....
Depends on how many you use. In my case, it was quite a bit less because I did six rooms all at once including two finished rooms in the basement with no windows where we burnt 10 bulbs for about 12 hours each day. It really did make a big difference.
I kept all the old bulbs and have been using them up in places like the outside lights.
The squiggly bulbs also last a lot longer then the regular bulbs much longer.
I think the average wattages of the squiggly blubs burn about 75% less energy then the regular bulbs and thats quite a bit less.
And, since these new LED bulbs run much cooler than the florescent ones, I would expect them to virtually never burn out.
Yep so in the winter incandescent bulbs help heat your home, but in the summer they cause you to use more power air conditioning your home.
