SACRAMENTO, Calif. It may soon be lights out for the traditional light bulb in California.
Assemblyman Lloyd Levine, D-Van Nuys, is proposing that the Golden State become the first to ban sales of incandescent light bulbs, by 2012. In their place, Californians could purchase more energy-efficient compact fluorescent lamps. Those are the spiral-shaped bulbs that cost more upfront but save money and energy over the long haul. Switching light bulbs is an idea that environmentalists have long supported. But getting consumers to embrace change has been slow going.
Banning energy-intensive incandescents "saves consumers money, saves the state money and saves energy," said Levine, who calls his measure the "How Many Legislators Does it Take to Change a Light Bulb Act."
But, "when a consumer is standing in a store and they're confronted with two different products, they generally opt for the one that is cheaper and the one they've traditionally bought," he said. "The problem is: The one they think is cheaper is only cheap at that moment in time. The other one is cheaper over the long run."
The compact fluorescent bulbs cost several times more than a traditional bulb, but they last 10 times as long. Replacing just one bulb that's used for four to eight hours a day can save a consumer $4 to $13 a year and $38 to $72 after five years, according to the American Council for an Energy-Efficient Economy.

We measure the color of light in Kelvins, the color of the glow that a black body radiator would have if it were heated to that many degrees Kelvin. An incandescent operates around 2800K, which is the reason for the yellowish hue. Around 4000K we see pretty much a pure white, moving towards bluish white as the temperature goes higher. "Daylight" lights are 5000-6500K. Regular daylight looks around 5500-5770K.
Big time. That's why in most offices, you can't listen to AM radio unless you're really close to a window, and even then, it rarely works well. If you're big on listening anyway, you learn to live with the buzz.
Internet radio is actually better most of hte time, but many, if no most businesses block it.
In your house it shouldn't really matter much. I did once try a CFL outside, and it took a couple minutes to get to full brightness when it was around freezing outside. It lasted two years before I moved and left it there. Bad electricity in your house could also shorten the life of a CFL, as will using one in an enclosure when it's not designed for that.
Yep, I've since learned that. And also that its a poor measurement to use when comparing fluorescent to incandescent light because the former is not full spectrum like the latter.
"This is liberal land. Liberals actually are not liberal. They are fascist elitist dictators who want to control every aspect of life."
Light bulbs! LIGHT BULBS?! These LIBERAL MORONS WANT TO BAN *** LIGHT BULBS?!?!?! ****
Arrrrggggghhhhhhhh. I feel like America's become an asylum, where our constant worry is finding small little hiding places against these would-be-wardens.
It's like horsepower for a car, an ancient measurement that doesn't really mean much as a single number.
Wrong. Read post 82. I didn't want to get into that much detail, but post 82 is exactly right. I have used 3200K, 2000 watt Mogul base bulbs in the past that would give you a real sunburn at 4 foot away in about 1 hour in a standard large reflector. This bulb used to be used in stage work. Lumens is another type of measurement.
Come on. Ever used a color meter? Visual color of light is the same. Spectrum has nothing to do with it. Otherwise the film making, bulb making, and the entire movie industry would go nuts.
I think new advancements in LED lighting will make CFL's irrelavent in about 15 years. Some of what I have seen is very encouraging. I love the potential of LED.
I heard on the radio, John and Ken here in L.A. that there is another bill in the works doing the same thing. the difference is that the first bill outlaws incandecents by 2019, and this one is by 2012.
Mr. Lloyd Levine is from the valley of fruits and nuts, the San Fernando Valley, Woodland Hills, Ca.
And he promised me personally he'd pay for my medical expenses, because fluroscent lights give me migraines.
Tonight, interiewed on KFI-640AM's "John Zeigler Show," The legislator behind this bill says it will ban sale of incandescents in CA, *not* use of them.
LOL
and I hope I'll be allowed to bunk in with my son - or maybe my grandson after he gets back to Texas (now stationed in Italy = Airborne Task Force - Rapid Response)or maybe my daughter and her hubby and girls - they just called tonite from Corpus Christie to tell me they just made an offer on a house there (they just got redeployed there for 3 years - he's a navy flight instructor).
My home state is Maine - raised in the north woods by grandparents/Grampa a Maine Guide, etc...I lived in Kalifornia for ten years, which was 9 1/2 years too many. I hied on back t'home here in Maine - but not as far north as where I grew up. However, I'm ready to get back up there and hibernate. More bear and moose than people...a good place.

Well, the International Cinematographers Guild seems to disagree.
Misuse of the Kelvin scale has grown with the use of light sources that do not behave in a manner similar to the "Theoretical Black Body Radiator." I can appreciate the need to use the Kelvin scale to describe the proximity of these newer light sources' color temperature to the well established incandescent and day light equivalents. However, there is no excuse for abandoning the caution "Apparent Color Temperature. "Correlated Color Temperature" does not imply as clear a caution as "Apparent Color Temperature." Worse yet, it suggests an accurate measurement, which it is not.
When one encounters a light source with an 'interrupted spectrum"(all fluorescent and gas discharge lamps), problems with color reproduction will arise. Just look at the full spectral distribution chart for that lamp. The peaks, often in yellow green range and elsewhere will cause problems. Color filters can be used to eliminate spikes. However, if the color is not in its spectrum, it cannot be added with a filter. Colors that fall in this interrupted area of the spectrum will be dulled or lost. If using these light sources is a must, it is best to augment lighting with a full spectrum source.
As your article says "I can appreciate the need to use the Kelvin scale to describe the proximity of these newer light sources' color temperature to the well established incandescent and day light equivalents" Did I ever say differently?
Saw this post and had to respond, i put those bulbs all over the inside of my home, my family thought i was crazy, but since not all of my kids have left the house and are up till just a couple hours before we get up in the morning i was trying to save on the water light and bond bill each month. ( at least in my mind i was trying) LOL I also spanked my kids( just ask them they will tell you) my daughter is of the now generation and doesn;t believe in it.
You got that right.CFL's= More R.F. pollution on top of noisy computer switching power supplies, monitors and cheap Asian TV's.
I'd like to outlaw Lloyd Levine. Not to mention the rest of his cohors in the assembly.
We need to provide power to the ever expanding population. OR, LET NO ONE ELSE MOVE HERE.
BUILD MORE POWER PLANTS.
