The yellowish-orange light that incandescent lamps give off is similar to the color of the light candles emit. There's no reason that we should stick to that puny sickly color. CFL lamps can do a good job of emulating daylight. Regarding energy. When I had incandescent lamps in our high hats I could warm the room by simply turning the lights on. This was an indicator of how much extra energy (and money) I needed to waste during air-conditioning season. No more. I had these for years. I would never go back. |

In 1966, the temperature in Corinth,Mississippi got down to nineteen
degrees below zero.I bet those Incandescent Light Bulbs felt good for hand warmers. cuhulin |

As already mentioned, it makes no sense to use CFLs in a hallway or stairway where the light is only on for less than a minute. It also makes no sense to use CFLs in decorative bathroom lights or ANY light where the fixture points down like an upside down tulip or a ceiling canister light. The upside down tulip or canister builds up heat which will kill a capacitor in the CFL. I also discovered a very interesting problem with CFLs and pets. The old fashioned fluorescent bulbs use a magnetic ballast that operates at 60hz and the flicker would drive some people crazy. The new CFLs operate at 20,000 hz and this " drive em crazy" problem has gone away. HOWEVER, the 20,000hz of the CFLs emit a 20,000hz sound that dogs and cats can hear and it drives THEM crazy. In an experiment, a CFL was put in a single room where a dog would frequently lay. When the CFL was installed, the dog wouldn't go in that particular room any more.
