finfife writes to tell us that GE has announced an advancement in incandescent technology that promises to increase the efficiency of lightbulbs to put them on par with compact fluorescent lamps (CFL). "The new high efficiency incandescent (HEI(TM)) lamp, which incorporates innovative new materials being developed in partnership by GE's Lighting division, headquartered in Cleveland, Ohio, and GE's Global Research Center, headquartered in Niskayuna, NY, would replace traditional 40- to 100-Watt household incandescent light bulbs, the most popular lamp type used by consumers today. The new technology could be expanded to all other incandescent types as well. The target for these bulbs at initial production is to be nearly twice as efficient, at 30 lumens-per-Watt, as current incandescent bulbs. Ultimately the high efficiency lamp (HEI) technology is expected to be about four times as efficient as current incandescent bulbs and comparable to CFL bulbs. Adoption of new technology could lead to greenhouse gas emission reductions of up to 40 million tons of CO2 in the U.S. and up to 50 million tons in the EU if the entire installed base of traditional incandescent bulbs was replaced with HEI lamps."The California legislature may want to revisit the wording of their proposed ban on incandescents (AB 722). How about mandating a level of efficiency rather than assuming that innovation can't happen?"

Politics: California Proposes to Ban Incandescent Lightbulbs 1074 comments
zhang1983 writes to tell us CNN is reporting that California Assemblyman Llyod Levine wants to make his state the first to ban incandescent lightbulbs with the "How Many Legislators Does it Take to Change a Lightbulb Act". The act will promote Compact fluorescent lightbulbs (CFLs) to replace the inefficient incandescent lightbulbs. According to him, "Incandescent lightbulbs were first developed almost 125 years ago, and since that time they have undergone no major modifications, meanwhile, they remain incredibly inefficient, converting only about 5 percent of the energy they receive into light."

If it took an hour's worth of electricity to start a CFL (the old myth said 3 hours, but let's just call it an hour), you'd need 20 watt hours to flow in 2 seconds. Now let's do the sums:
20 watt hours is 20 * 3600 joules, i.e. 72kJ.
For 72kJ to flow in 2 seconds, you would need 36kW of power. 36 kilowatts. Your biggest appliance is probably your electric shower, a powerful one is 10kW.
To put 36kW into perspective, this is 150 amps at 240 volts.
Your entire supply from the power company is probably on a 40 amp breaker. Even if the 'kickstarting' myth was true for only 20 minutes power rather than the oft-quoted 3 hours, you're still going to blow your main breaker.
As you can see, the 'kickstarting' myth is implausable.
The reason why you might not use a CFL in a cupboard in which you only use the lights for a few seconds at a time is many of them take a couple of seconds to start, which is annoying for a light you only use for a few seconds at a time. But if you want high efficiency in that situation, you can always use an LED downlighter (available conveniently in a GU10 halogen downlighter form factor).

If you're not getting "warm" colors from CFL bulbs, you're probably using older bulbs. The flickering also points to this. My wife can't stand CRT monitors at 75Hz, but she hasn't complained about our CFL bulbs flickering. She's also got insanely good hearing and doesn't hear them buzz.
This is like the complaint people have with diesel engines. Yeah, the first diesels in the US were smokey and loud and slow, but new ones are virtually indistinguishable from gas engines and use 50% less fuel or more. Yet, people still avoid them because they don't want a "noisy, smokey, slow diesel car."

Also, CFL's come in a range of color temperatures, some of which match "warm yellow" from traditional incandescents. They're not all "hard white".

This is mostly a Political Marketing statement, trying to forestall bans or taxes on incandescent bulbs, as although incandescents costs more in the long run, they are cheaper when you pay at the register so people still buy a lot of them.
Personally, I'd not want a BAN on incandescents, just a "wattage tax" on lightbulbs, say $4/100W tax on bulbs regardless of the mechanism (LED, CFL, incandescent). Just something equivelent to 1 hour a day use for 1 year (assuming

Why does nearly everyone on /. assume that every company is out to deceive them? or that every press release (unless it's from Google or Apple) is a marketing lie? Sure every company is out to make money, but not every company is an Enron. CFLs are the perfect product, I use a ton of them, but there are certain applications where they are too costly to run because of less time on vs on/off cycles. I welcome this if they work as well as regular bulbs and last as long they will allow me to bring those rooms in line with the cost savings that my other rooms get with CFLs.

I think it's because nearly everyone on Slashdot can be described by what I call the 3P Syndrome. Specifically:
Pissy. More often than not, Slashdot readers seem to be pissy. They are easily goaded into responding to trolls and participating in flamewars. They will stubbornly support an illogical and inane position simply for the shred of joy they coax from a heated argument. In short, they are easily irritated.
Pessimistic. Many Slashdot readers are pessimists. They look for the worst-case scenarios and will dismiss any possible silver lining of any act or concept.
Paranoid. Slashdot readers may also be naturally paranoid. This is perhaps the biggest reason for apparent distrust of others' motives. Serious paranoia makes it very difficult to trust others, and it is only exacerbated by the first two factors.
Even before mind altering drugs are considered, all Slashdot readers seem to contain these three qualities in varying amounts (some appear to be "normal"). But collectively, they sum up to a critical mass that gives Slashdot that unique community feel.
I haven't thought up a satisfactory answer for Google and Apple, though. Maybe Slashdot users identify with them on some level.

I noticed several responders mentioning taxes and such. It's a mindset we have to be careful of. There's an attitude I noticed with a lot of SUV drivers that they'd prefer to pay a tax and keep driving the beasts. The problem is we need to get them off the road period not just tax them. There was an argument made in Who Killed the Electric Car? that we'll need more coal plants for all the electric cars. Well here's a little food for thought. If all the incandescents were changed to compact florescents not only could every home in amercia charge their electric cars without needing more plants and their electric bills would actually go down. Electric lights are still the biggest single use of electricity in this country.

I own an SUV. I telecommute roughly 90% of the time, and can go days without even starting that vehicle. There are also times when I start the vehicle, and drive it to go do something that involves other people and payload. If I didn't have that vehicle, we'd need four small wind-up passenger cars to haul the passengers and payloads. There are no small, more-efficient vehicles that can go where I can go, and get the people there, too. What's more efficient? Four cars burning fuel, wearing down tires, occupying road space, and possibly getting dangerously stuck enroute to the destination... or, one vehicle that can carry at least half a dozen people and hundreds of pounds of payload on rough roads, through the mud or snow, and safely do so?
Why should my vehicle be "taken off the road," but some college kid that drives 100 miles in his hybrid in one weekend bouncing between parties while I drive nowhere, gets to use his? You're holding the tool accountable for what people do (when you don't like the people that use the tool), and not even touching on the wasteful habits of people that use a marginally more efficient tool that you like better.

I think you've probably not even come close to using all of the available CPU cycles on your computer while you were busy being snide, so it's probably better for the environment if you use a much slower, lower-powered machine. Perhaps one of those wind-up, one-laptop-per-childish-user ones they've been talking about? Or... DO you use your computer entirely to its capacity? Doesn't matter. Even if you do, you're only in the minority, and since the majority of people with fancy computers don't really need them, we should probably not allow anyone to have them, right? Give it a rest.

I decided to be a good citizen and replace the burnt out bulb in my bathroom this weekend with a Daylight CFL that's rated at "42 watts but gives off as much light as a 100w incandescant". I put it in, turned it on, and could get the damned thing out of there fast enough. The light color just sucked... was far too "flourescent" for anyone to stand. I'm sure *someone* out there likes the sterility and coldness of flourescent light, but it sure ain't me and my wife. I went back to Home Depot, returned the bulb, and bough a high effeciency Halogen that takes 27 watts but puts out as much light as a 100 watt bulb. The perfect color of light, higher effeciency than the CFL, and lasts two years.... and it's an "incandescent" that would be outlawed.

After 100 Years The Innovation Hasn't Happened (Score:5, Insightful)
The reason people assume innovation can't happen is that it hasn't happened in incandescent light bulbs.
Anyway, twice as efficient is bullshit. Incandescent light bulbs are so outrageously inefficient that you are still wrecking the planet even with these new vaporware bulbs.
Banning incandescent bulbs will only spur innovation in LED and other modern solutions. Complaints about the quality of light are very valid, but when you have an LED bulb that is generating the same brightness as an incandescent and the LED is using 1% of the power and has 1000x the lifespan then it is time to get the incandescent bulbs out. You can replace an incandescent with an LED and still have power left over for a notebook computer with dual processors.
These new incandescent bulbs make me think of a non-hybrid gasoline car that ekes out 50 mpg so "you don't need a hybrid" but the point of the hybrid is not just to double the gas mileage today
