JS you got any family with the initials "BS" ? ;;-}} I live in California, it is always warm enough for lightbulbs to work. grin Regards, JS I use a combination of old fashioned and new fashioned CFLs. 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.
