Have you replaced at least half of the lighting in your home with energy efficient CFL or LED bulbs?
Almost all replaced. Still replacing the electrical system.
Yes we have.
Unfortunately. They don't last as long.
I know, right? CFL's claim to last longer, but that hasn't been my experience at all.
I was an early adopter and switched mine about six years ago. The problem I'm having now is that they've stopped making the ones I need to replace the ones I have. It's quite frustrating and I've had to go back to incandescent in two fixtures.
Or, I can replace the fixtures, but that frustrates me.
I think they're almost all CFL now - I had a free box of about 20 from the power company and a lot still haven't been used (small apartment, not many lights), so I haven't tried LEDs yet.
