Bright ideas for energy efficiency
May 1, 2007 -
Cheaper LEDs to light a green path?
January 19, 2007
The Energy Committee of the Senate is working on a bill, which may hit the Senate floor later this month, that will ask the federal government to set national standards for energy efficiency. A coalition of consumer groups and manufacturers is now trying to come up with standards for lighting to support that goal. Among the ideas being discussed is phasing out standard incandescent bulbs over the course of about a decade.
The move builds on the momentum to phase out incandescent bulbs, which are less expensive but consume far more power than do compact fluorescent bulbs, light-emitting diodes and systems that bring sunlight indoors.
In February, California Assemblyman Lloyd Levine introduced a bill banning incandescent bulbs in California by 2012. It was criticized as another example of kooky California legislation. But since then, legislation banning incandescent bulbs has been introduced in Ottawa and Australia.
There are about 4 billion screw-in sockets containing incandescent bulbs in the United States, according to a spokesman for the Energy Committee. Incandescent bulbs are also incredibly inefficient.
Some researchers estimate that more than 90 percent of the energy that goes into these bulbs gets converted into heat, not light. That's why Easy-Bake ovens work. (Some incandescent-lightbulb fans like to claim that the bulbs help heat their home, but it's a fairly inefficient way to heat a room. Ceiling lamps, after all, end up heating the ceiling.)
Approximately 22 percent of the energy consumed in the United States goes toward lighting, according to the Department of Energy. Approximately 52 percent of the electricity generated in the United States is produced by coal. The hope is that the switch to more efficient lights will lead to the need to burn less coal or build fewer new coal plants.
If legislation is passed, the most likely immediate beneficiaries will be manufacturers of compact fluorescent bulbs, those curlicue bulbs promoted by retailers like Wal-Mart Stores. Compact fluorescent bulbs cost more, but they use about 25 percent of the energy of an equivalent incandescent.
LED manufacturers, though, would likely benefit too. LED bulbs are actually somewhat rare right now, and they cost significantly more than regular lightbulbs. LED lamps, though, are coming down in price. Advocates also say the quality of light is better than what's available from fluorescents.
But don't count out incandescent bulbs completely. General Electric says it plans to come out with incandescent
Some manufacturers actually make all of these types of lights.
Then there are the more novel ideas. Fiberstars has come up with a system for lighting freezer cases in stores with fiber-optic cables. Other companies have come up with organic light-emitting diodes, or OLEDs, that could turn an entire wall into a lamp.
Legislation banning products has often come under fire from some politicians and economists, but it has worked. In the mid-1970s, appliance manufacturers vigorously fought energy efficiency regulations in California for appliances like refrigerators.
The regulations passed and led to a creative wellspring in appliance design. Now refrigerators consume less than half the electricity of older models but hold more food and cost less, in terms of real dollars.

The end result is that politicians will be passing laws 20 years from now forcing us to switch to something else to clean up all our ground water that is infused with mercury because they mandated we all use CFLs.
And one more thing - CFLs will do little to impact the peak electric power requirements. Electric demand is at its highest during the weekday. This is a time when florescents are already in use for lighting in the majority of offices, schools, retail stores, and workplaces. CFL's target largely the home market, and would get used outside the peak times for electric demand (ie, night). The end result is that we'll still need the same number of electric power plants because we'll still need to meet the peak electric demands made during the day. All this nonsense about converting to CFL's leading to needing fewer power plants is simply BS.
I don't agree that the gov't should subsidize stuff, though, because that money comes from the bank accounts of tax payers, which means that greater subsidization equals greater taxes.
Can't do this, can't **** here, can't **** here, can't have kids here, can't speak here, must do this.
A smart politician would never do this, he would get voted out, like the stupid Bush administration and anyone that had anything to do with them will soon.
And DARPA funded the early ARPANET as a way to keep up communications between American cities in the event of nuclear war (networks that could withstand catastrophic failure). I'm sure THAT would have been a real self-starter in the 'free market'.
Grow up. 'Free enterprise' and 'free market' is comic-book reasoning for impressionable young Republicans. The world doesn't work that way.
Maybe your grandchildren can explain it to you in Chinese...
And the 'American free market' did wonders for the Auto Industry, yeah... Extinct Ford Excursions as the tombstone of a dinosaur American company, as Toyota passes them by, embracing the 21st century. Toyota had a cooperative government, national health care for their employees, politician-planned R&D for decades... Oh I'm sorry, that wasn't in your 'American Economics 101' comic book ?
Zaijian, American Empire !
I intend to light my house with a 1w white argon laser.. I can route little mittors all over the house to light in every room. Ok I'm jokeing but it would be cool.
Seriously though, I intend to light my home any damn way I please.
Your tax dollars at work, and the result of everybody who continues to vote Democrat or Republican -- they're both the same, they want more control over what you and I do -- even when it comes to lighting our homes and flushing our toilets.
in an alternative universe where laws are never stupid, as this
one certainly is.
Half the lights in my apartment are fluorescent because they
stay on for a long time each day in areas where a lot of light is
needed. There they make sense.
Half the lights in my apartment are incandescent because little
light is needed in those areas and, unlike fluorescents,
incandescents can be dimed down to use less power. They're
attached to dimming controls.
MESSAGE TO CONGRESS: This illustrates a point that comes up
often in our relationship. I'm smart and you're stupid. There's no
need for you to keep coming up with these dumb ideas to
demonstrate that point yet one more time. It's a fact that we
both must live with.
If you're absolutely obessed with saving electricity because you
think the earth's about to become a cinder ball, adopt two
policies that'll only affect you and your rich celebrity buddies:
1. Turn off all the lights that illuminate government buildings in
DC, particularly the Capitol dome. And never, never, never fly by
private jet.
2. Take up Michael Crieghton's suggestion and ban all private
jets in the US except for medical transport. Let your rich and
celebrity buddies fly commercial like the rest of us.

heating up the dimmer instead of the bulb... Keeping the bulb dim
seems a specialty of yours...
I honestly don't see how the florescent bulbs are any better. Sure they save power but they are toxic, incandescent aren't. With all of the extra driving need to dispose of the florescent ones that is going to add to the pollution.
I think it is a bunch of pooh! myself.

I can hardly wait for the solid state lamps that are even more efficient.
Disclosure: I own stock in four electric companies and it will be advantage to them (and our dividends) in not building ever larger generation plants, transmission lines and pollution controls.
Perhaps a wattage tax on hot filament lamps would speed the transition. Consider that California has about a tenth the population of US it alone might be the trigger to make change over a done deal.
Final thought: Since the lower power used and lack of hot filament, the surface is only warm to the touch. That should reduce fire risks significantly. Our bed lamps are cool, and unlikely to start a bedding fire compared to ordinary lamps.
Why should someone who likes incandescents but keeps his lights off be penalized, compared to someone who uses fluorescents but leaves his lights on?
And bedding fires are nearly always caused by smoking or candles, so that's a non-issue.

I've got some great dot-com stock that I'd like to sell. Would you like some?
It would be far more effective to state that the energy efficiency of a light bulb producing X lumens must be Y as even if incadescent light bulbs can not produce this level of efficiency today as it would allow companies (like GE) the flexibility to improve the incandescent light bulb if they think they can make it efficient enough.
our sun where as fluorescent bulbs create an unnatural greenish
light. If incandescent bulbs are to be removed from the shelves
before an exact replacement (power saving) bulb is developed you
can be sure I'll be buying hundreds of incandescent bulbs in
advance of such a ban.
Our lighting project benefit as well!
That said, now I know to avoid your company studiously, and will advise others to do the same.
Any company that would stoop to your level of spamming would just as easily stoop to shoddy materials and/or workmanship.
IOW: **** off.

Flourescent light bulbs in a house cause too much shortwave and AM radio interference (yes, there are some of us who care about that). The light produced by them is not full spectrum either.
Getting rid of incandescent bulbs is not the total answer. Unless a new type of bulb is invented that does as well as incandescent bulbs, don't ban them!
The other problem is size. LEDs currently can't be too large or they experience issues, unlike incandescents which could be as big as they really want to be.
High quality LEDs, such as those used in flat panel display indicators, can last for years without going out. Some are so strong they can effectively light part of a room. And that's just a TV indicator.
flickering...Led's are direct current devices and if fed a constant
voltage don't flicker... the great waste of energy in converting our
distributed ac to dc by almost everything that uses electricity is
conveniently ignored.
But LED flicker? I've seen fluorescent bulbs flicker, but not LED.
Candle Manufacturers [b]GET READY TO RU-U-U-MMMMBLLLLLE!!!!!!!!!!!!!!!!!!!!!!!
very misleading statistic with respect to these flourescent bulbs, since most of the energy for lighting involves office buildings , highways, etc. that already use flourescent fixytures. Residential lighting is where you find the vast bulk of incandescents, and there 8.8% of U.S. energy is used for lighting. Of course, residential lighting also includes some flourescent which wouldn't be affected.
Another problem with these bulbs is that they use mercury and would have to be recycled. Another problem is that there are no versions at the present that are 3 way bulbs and none that can be used to replace candelabra and other specialty type bulbs. I use the new bulbs msot places in my home - they save money and last a very long time-
a 60 watt equivalent bulb only uses 12 watts. I do want three way bulbs, however.
But I've been using a 3-way CFL in my livingroom for about two years now. There are also more decorative CFLs, and even dimmable ones, although they do cost more. Some of them might fit your candelabra/specialty bulbs.

I'll stick to Incandescents.

- The CFLs I've tried burned out quick when used where I only needed it on for a couple of minutes to find something. They also seem to burn out when plugged into the same outlet as an electronic speed control for a motor. These design flaws need to be addressed.

- The first batch of CFLs I bought (from local stores like Lamps Plus, Walmart, etc.) weren't so great.

- Most fluorescents are used on dedicated circuits, where they do fine. But if they're not, there can be problems with voltage fluctuations and RFI due to other things on shared circuits. My experience with the longevity of CFLs in plug-in lamps has also been disappointing, and I suspect that's the reason. There still seems to be some work needed to make them a truly suitable substitutes for incandescents in some situations.

Showing 1 of 2 pages (77 Comments)I doubt CFLs will ever work very well in an area subject to temperature extremes, like a front porch in northern climates. The bulbs start out dim and get stronger as the bulb warms. It's going to overheat if it starts bright at -20F.
Like you said, they "start out dim" and take a few seconds before getting to full brightness. They also give off a horrible color, and some weren't as bright as their incandescent counterparts.
It depends on what company makes them. I haven't been back to the local stores for CFLs, so I don't know if they've stocked better quality CFLs. I did, however, find better ones online. These were brighter, had better color, and turned to full brightness instantly.
One thing that I haven't tried is to put one where there would be extreme temperatures, so I don't know if they've improved the technology on that end. But considering the other improvements, it's not unlikely that such a issue might have also been addressed.
