My main criticism is actually the light quality. I switched to halogen lamps, so my 100 watt incandescent turned into a 72 watt halogen. Full range of dimming. Finest color rendering available, 33% less watts.
As I move around the house I turn things on and off. I basically bring my 75-150 watts around the house with me. It’s literally not worth my quality of light to use LED or CFL right now, I think it looks terrible and it’s not how I want to spend the 6 hours or so of my lit time at home. I get enough of it during the day that I’m willing to pay the higher energy cost because it’s very minimal in the overall scheme. HVAC, the hot water heater, the dryer, these things use real energy.
LED and fluorescent are perfect for retail and office environments. These sources are on 12 hours a day, low energy high output, and stay on no matter the amount of people in the open office. I’m all about bringing down that energy use to less than 1.1 watts a square foot.
