GE Announces Advancement in Incandescent Technology 619

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?"

        What gets on MY chimes is the fact that the politicians are considering laws banning incandescents and moving towards CFBs... and, suddenly, GE announces a "new" technology that will let incandescents be just as efficient.

        I mean, I'm not putting on my tinfoil hat just yet, but the timing here seems to be more than coincidental. Just how long has GE been "researching" this technology?

      Recent, name-brand CFLs have mostly acceptable color rendition. Where you will notice their shortcomings is with deep red objects, like red velvet. These usually appear as brown or magenta under triphosphor CFLs, because there is simply no real red in the spectrum.

      Now, there are halophosphate and mixed halophosphate/triphosphor lamps which achieve > 90 CRI, but they trade off brightness. Chroma 50 tubes come to mind.

      People like to mention LEDs as a solution. They're great for low-intensity lighting, but

      In understand that this is slashdot, and therefore RTFA isn't required, so here is the relevent section from the link:

      "(3) A general service incandescent lamp does not include an appliance lamp, black light lamp, bug lamp, colored lamp, enhanced spectrum lamp, infrared lamp, left-hand tread lamp, marine lamp, marine signal service lamp, mine service lamp, plant light, reflector lamp, rough service lamp, shatter resistant lamp, sign service lamp, silver bowl lamp, showcase lamp, three-way lamp, traffic signal lamp, or vibration service or vibration resistant lamp."

        Why would you want to use an incandescent light in this? I think a lot of cities are switching to LED lamps here because they use much less power and last longer (so they don't need to send out expensive crews as often).

      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."

      Have you tried any of the newer CFL's with non-magnetic ballasts? The oscilation frequency is now much higher, beyond what the human
      eye can typically perceive.

      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".

      A quick reference: http://medfordcan.home.comcast.net/Myths.html [comcast.net]

        • Also, according to this site [lamptech.co.uk] (which manufactures low-pressure sodium lamps) doubling the efficiency of traditional incandescents to 30 lumens/watt would leave them less efficient than halogens and LEDs, and still far, far short of fluorescents.

    Here's why. These are INCANDESCENTs. Glowing filliments. You can try to reduce the radiation in the UV and IR, but you aren't going to get rid of it. Running hotter (the Halogen way) ups the UV content which gets filtered out or flouresced down (and if you have a flourescent coating, why not just have a compact flourescent).

    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 .14 kwh power cost), so that at the register you actually see what the bulb will cost.

      I highly doubt that this is simply a marketing statement or that it was a technology that they were just sitting on waiting for proposed bans on their products. Likely they noticed that CFL were cutting into the sales of their regular bulbs and developed the technology so that they can compete.

      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.

        You can make them more efficient by running them hotter (its how halogens work), and this breakthrough is probably a similar high-temperature filliment strategy, allowing you to get the halogen efficiency (better than a standard incandescent but worse than a CFL) out of something fitting in the standard incandescent form factor. But you can't beat direct radiation technologies (CFL, LED).

        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.

        • Many/most /.ers are engineers or like-wired people. You cannot be pessimistic and survive as an engineer or developer for very long. You have to be able to believe that the thing you are designing/developing can and will exist even though when you start out it likely does not exist. That is surely not pessimistic.

          The flip side, however is that you can't just wish problems away or ignore them. Good engineers actively seek out the problems and figure out how to address them or work around them.

      I agree on the overstating of efficency. Odds are the process has been known for years how to make the bulbs more efficent but chances are it would make them more expensive resulting in fewer sales so they never moved ahead with the technology. The hands down winner though are LED bulbs. They use little power and have insanely long lives and don't suffer from surge shock like filament bulbs and even flourecent. The problem is obviously cost. It'll drop but it's hard to say how much and how fast. They are already being used in hard to reach areas to avoid the labor expense of replacement.

      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.

      • Because taxes are a much better mechanism than an outright ban. There are still reasons for incandescents (there are NO good chandileer style CFL bulbs, CFLs are less weather resistant, etc), and if those uses are worth something, they are worth an extra buck or two a bulb.

        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.

      They might be using tungsten photonic lattice technology [sandia.gov]. Note that this is an article from 2002, and claims a similar efficiency. IIRC this was discussed on /. at the time:

      Now a microscopic tungsten lattice -- in effect, a tungsten filament fabricated with an internal crystalline pattern -- developed at Sandia has been shown to have the potential to transmute the majority of this wasted infrared energy (commonly called heat) into the frequencies of visible light.

      This would raise the efficiency of an incandescent electric bulb from five percent to greater than 60 percent and greatly reduce the world's most vexing power problem -- excess electrical generating capacity and costs to homeowners caused by inefficient lighting.

      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 .14 kwh power cost), so that at the register you actually see what the bulb will cost.

      I'd want neither bans nor taxes. Rather, leadership by example. Here's what I don't get: the State of California itself purchases a huge number of light bulbs of every sort. Why don't they just pass new procurement rules? If the government itself uses only Compact Fluorescent Lightbulbs (or whatever's trendy), the rest of us Californians will be exposed to them. If the new bulbs really are better, we'll all follow in time.

      I come from Iowa. When I got here, people told me about the difference between midwestern liberals and Californian liberals. I'm starting to get it...I don't appreciate this nanny state "we will tell you what kind of light bulbs you must buy" thing.

  • On the one hand, GE is the market leader in CFLs (thanks to Wal Mart) & is building another plant or two in China so they can increase production.

    OTOH, each and every CFL is handmade, which is why they're so much more expensive.

    My guess is that these HEI bulbs will be significantly cheaper, even if they don't have the same lifespan, which should make them a net plus. And you can put them into fixtures that CFls are either cosmetically or technically untenable.
    • Virtually every CFL I have had lasted less long than an incandesent. I major plus for this new technology would be a low wattage bright bulb that fits current fixtures. I have a lot of fixtures that cant use them, as well as outdoors or inside the oven.

    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.

      That's because you got a Daylight model. You can buy CFLs in incandescent orange if you want. I have one in the lamp across the room right now, and it's virtually indistinguishable from the incandescents I have (certainly a 'warmer' colour than halogen lights, that I have in the downlighter fixtures).

      You can get CFLs in pretty much any colour you like.

      That's because you bought daylight bulbs. They are supposed to look like that since their color temperature is typically 6500K which approximates the color temperature of the sun. If your eyes have not adjusted to it and there are regular warm bulbs nearby then it will look bluish. Next time buy one with a lower color temperature, like 2800-3500K. See http://en.wikipedia.org/wiki/Color_temperature [wikipedia.org] for more information.

        Not to be pedantic, but I do need to crrect a misperception.

        Actual daylight is anywhere from 4400-5600k. Daylight-balanced incandescents like SoLux bulbs are at 4700k and are similar to mid-morning light. Note that the color of "daylight" on a reflective white surface is highly subjective depending on atmospheric interference, latitude, and of course, time of day.

        6500k is a normally-used tristimulus daylight benchmark - accurate for transmissive media like RGB computer monitors, but not for bulbs. A computer monitor calibrated to a D65 at 2.2 gamma will show the aforementioned white board photographed in the sun accurately, but it not, strictly speaking, daylight-balanced - merely tuned to reproduce daylight using three component colors. Hence, the higher color temperature than "real" daylight.

        I prefer to measure in mireds!

      W. has given a series of tax breaks to Coal and Oil and has our troops guarding major pipelines where the oil companies are having issues (Iraq comes to mind). In addition, he has dropped a number of needed environmental protections and possible fines. IOW, he has artificially lowered the costs of Oil and Coal. He is pouring money into hydrogen research, while trying to cut all other avenues.

      OTH, there has been damn little incentives for nukes or Alternatives. Now you have states offering incentives for highly unprofitable solar or even ethanol production (which is still unprofitable)and saying that they will ban products. What is needed is for gov. to drop all the incentives and the playing games with picking techs. If they want to encourage us to move away from imports and dirty items, then simply increase the tax on a good in such a way that it encourages alternatives. In particular, rather than banning incandescents, a simple tax based on energy usage would have a much higher impact on creating alternatives. In fact, if they go the route of taxing the energy, then they should tax the pollutants such as the mercury. But this approach of gov. encouraging a particular tech is fool hardy and will lead us down the same road. Basically, it will put the west on a single type of tech which will give us the same damn problem.

    LED's are the way to go if you ask me. Long life span, great performance, more color availability (more "soft" colors/natural looking lights). LED flood lights put out 200-300 lumens @ 7-11 watts of power. I replaced 16 external lights with LEDS and while it was a bit upfront cash my power bill has dropped drastically and no more whipping out the ladder every 2 months to replace burned out bulbs or ones damaged in the weather.

    less garbage over the lifespan, less electricity, less footprint. Seems a dollar short and a day late if you ask me.

        I did a search on froogle and found a few sites that had great prices. LED is getting VERY competitive and what was 99-120.00 a light a year ago is around 39-51.00 a light if you don't mind going with a non "boutique" name.

        I purchased 20 LED "flood" lights and got a quantity discount. A decent investment upfront indeed but my first bill has already shown how much the others literally "sucked". Perhaps with people putting priority on these lights they will get even cheaper.

      White LEDs are actually not very good for color in many cases. Most white LEDs actually only produce blue, and through the use of a scintillator, mostly yellow light. The yellow is the wavelength which affects the eye by stimulating both red and green since the wavelength is in-between. The result of this is that when using it to look at various objects, the reflected colors are often pretty bad. See http://en.wikipedia.org/wiki/LED#Disadvantages_of _ using_LEDs [wikipedia.org].

      As per the FA you linked yourself, "GE will close the 96-year-old plant in Wellston on Wednesday and lay off 175 workers because of rising imports and slumping domestic demand for the soft-white standard incandescent light bulbs assembled there."

      Yeah, but are those LEDs going to cost $50 a bulb while the fancy new incandescent is less than $0.50 a bulb? LED bulbs are super cool, but also well outside of affordability envelope at the moment. I think LEDs are the future (until something better comes along at least), but right now they're just not practical.

      You're absolutely right... except the same companies that make the incandescents are the ones making the CF bulbs. So this is an internal competition among research and manufacturing divisions rather than some conspiracy to sell power. Same thing will happen for LED bulbs. Unless their massive R&D investment is also due to some legislation unreported here. As long as there's more than one company, or part of a company making competing products they will... well... compete.

  • One thing that neither the article nor GE's own press release [geconsumerproducts.com] mention is if these bulbs will last longer than their traditional incandescent counterparts. I have owned one particular CFL bulb for over four years. It has been one of my primary light sources—in operation for tens of thousands of hours—and still works almost as well as the day I bought it. Traditional incandescent bulbs don't last anywhere near that long.

    In buying the CFL, I've saved not only in electricity but also in replacemen

    Typical tungsten bulbs are about 15 lumens/Watt. The HEI described get only 30 ln/W. Your old stand-by T12 fluorescent tube in the drop ceiling troffer of a old style cube farm get 50 lm/W. Currently available T5 tubes get 100+ ln/W with improved performance on the way. There are dimmable CFLs out there. Controlling fluorescent brightness is very simple in modern high frequency electronic ballast with PWM. The reason you do not see more dimmable CFLs is due to the small increased cost. In the long run, CFLs are a less optimized solution compared to separating the ballast from the bulb as you might see in many commercial (and some residential) recessed can fixtures. Why replace the ballast every time the bulb goes (hint: CFLs fit into existing sockets)? Also, the old color, flicker and lifespan issure are a tthing of the past with modern electronic fluorescent ballasts. While great tings are promised in LEDs (>150 lm/W), the best LED bulbs that I've seen are only 25 ln/W, but I'm sure there are better out there.

    > How about mandating a level of efficiency rather than assuming that innovation can't happen?"

    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 ... it's also to uncouple the gasoline from the drive train so that the car becomes agnostic about its energy source and the gasoline part can be replaced more easily with a fuel cell or battery or whatever other technology. The hybrid has room to grow and improve whereas a non-hybrid car getting great mileage is still stuck on gasoline. It's just a band-aid to cling to an old technology like gasoline or incandescent bulbs.

    So how is the consumer going to know which light bulb to buy once these come out. I know how bright a 100W bulb is compared to a 40W bulb. Will I have to buy a 50W high efficiency bulb that gives equivalent light of a current 100W bulb? Lets say i walk into the store and need a reading light for my room. I want to get something fairly bright so I look for the 100W bulb. I have the option of buying the old 100W bulb or a "new" 75W bulb. I will go with the 100W bulb because I'm a dumb consumer and assume it will be brighter even though the high efficiency 75W bulb produces more light.

    This poses an interesting issue for the marketers to tackle once this goes to market. Hopefully they will be able to properly convey the "light output" as the deciding factor rather than the wattage.
