I put CFL's in this house when I purchased it in 1995. I have replaced only three bulbs of the thirty-five that are installed. My foray into LED's has found them to be very dear and the light does not have enough range. The only incandescents are in the fridge and the cooker.

As far as power fluctuations in rural areas go, for many years I lived at the end of a long stretch of line through many miles of forest. Line conditioners only make the problem worse. A battery backed conditioner was always necessary for the computer, and being ready to shut it down quickly was also important. The CFL's hate the switch over from commercial lines to generator and back that is a daily routine in many rural ares. (They croke quickly)
