Pretty much all LED, CFL, and floro in my place. Let's do an inventory...
- Porch light is a 5000K EcoSmart 60W equivalent
- Living room has an entry light with candelabra-base bulbs - the sole primary fixture with incandecents. The ceiling fan in that room has CFL's. A similar fixture over the stairs has candelabra-base CFL's that suck.
- Dining room has a T5 circline floro fixture that replaced a gaudy builder-grade chandelier.
- Kitchen area has a 3000K bulb over the breakfast nook, 2 twin T8 floro fixtures lighting the kitchen, and a Utilitech 2700K 40W equivalent bulb over the pantry door that's been burning for more than 4 years continuously
- Back porch has a ceiling fan that's hopelessly broken - last incandescent in it died years ago so it's no longer used, similar to the back porch itself
- Downstairs bathroom is sporting a trio of Cree 4Flow bulbs - 2x 2700K, 1x 5000K 40W equivalent
- Utility room sporting one of the few can fixtures in the house has a Cree LED floodlamp in 5000K 60W equivalent
- Garage sports 3 twin T8 floro fixtures
- Upstairs hallway has a purpose-built 4000K LED flushmount fixture
- Office has 3x Cree 5000K 60W equivalent bulbs in the ceiling light fixture and a cheap EcoSmart 3000K 40W equivalent bulb in its closet
- Guest bedroom has 3x Philips 3000K 60W equivalent bulbs of a vintage that are somewhat failure-prone ... since that room is almost never used, not a big deal
- Upstairs bathroom has 4x Cree 4Flow 40W equivalent bulbs (2x 2700K, 2x 5000K)
- Master bedroom sports a crude color-mixing arrangement in the ceiling fan (1x 2700K, 1x 5000K) with limited effectiveness because the bulbs point opposite directions
- Master bathroom has 2x six-bulbs fixtures with a motley assortment of 2700K 40- and 60W-equivalent CFL's. Some ancient GE ~2700K highly directional LED bulb over the toilet.
- Master bedroom closet sports the same arrangement as the office closet
Sure, there are incandescents in the oven, stove hood, microwave, refrigerator, and dryer. No huge benefit to replacing any of those and only the refrigerator is a likely candidate for it anyway.
All the living room fixtures are going to go at some point in the future - they're gaudy builder-grade faux brass and I've replaced most of the fixtures in my house with brushed-nickel. Whenever someone makes a decent LED bulb
(3200-3500K anyone? anyone?) I'll probably swap for some pendants for the two candelabra fixtures alongside a new ceiling fan and be done with it.
The master bathroom fixtures are where my collection of CFL's is slowly used up. Not looking forward to replacing them, but again the
faux brass has got to go.
I've not mentioned my various homebrew LED lighting projects.
Actually, if you live in cold environments and need a heater, incandescents are actually a good option and you don't gain anything with using more efficient lighting. Incandescent bulbs are mini heaters and are actually very efficient. 80% of energy comes out as light (although most is infrared) and the rest is heat. (The "inefficiency" people talk about is actually "inefficacy"). So your incandescent light bulbs help heat your home.
This is the opposite in hot environments though.
Relative to the
tens of kilowatts it takes to heat or cool a home, a few hundred watts of incandescent won't make much of a difference. And as opposed to the
convective effect of air, they're
radiating their heat all over the place which has to be absorbed then transferred to the air.
