GE Announces Advancement in Incandescent Technology

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?"

      most people here assume because they can't see something nobody can

      That assumption is usually well-founded in reality. People who are "sensitive to radio waves" get sick a couple of weeks after a cell-tower is erected, even if it is never turned on. People can hear ultrasonic differences between two soundwaves, just not when they're in a double-blind test.

      Fact is, our sensory equipment is relatively slow and where we can sense high frequencies, we do so by exploiting a physical or chemical transformation that turns them into a slow signal. What you call "high refresh rate" is orders of magnitude slower than the frequency of all but the cheapest CFLs. There are great differences in the cognitive abilities of different people, but due to the way human senses work, there are limits to these differences. You do not see 40kHz flicker (and not subconsciously either).

    Good god I hope California does put in a minimum efficiency rather than just outlawing Incandescants....

    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.

      They are supposed to look like that since their color temperature is typically 6500K which approximates the color temperature of the sun

      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.

    Of course there should be skepticism, because it sounds like GE pulled some amazing innovation of out their subsidiaryhole just in time to fend off legislation.

    Of course any legislation that talks journey rather than destination is misguided -- it is efficiency and other measurable metrics (e.g. amount of waste per unit, for instance) that matters, not how you get there. Putting specifics into the wording sounds more like some lobbyists got their money's worth.

    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.

    Why? General Electric is probably the largest manufacturer of CFLs. Because there's more to the manufacturing process of a CFL, they're more expensive to make. Assuming that they have a 10% profit margin on both, the CFL bulb will make them more money.

    My guess is that they know there is still a demand for incandescent technology for specialized applications and for those who demand incandescent lighting, so they have found a way to make it more efficient. Perhaps not as good as a CFL or LED, but nonetheless, its a win-win for cases where incandescent is ultimately used.

    They might be using tungsten photonic lattice technology. 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.


    Five years to market doesn't sound especially unreasonable to me.

    The hands down winner though are LED bulbs.
    Do some research. They're not that more efficient that CFL, and they are not very bright. They work well for spot lights, but are terrible as general light bulbs that cast light in all directions.

    LEDs are over ten times more efficient and the directionality of the light can be solved in a number of ways. Mag-Lite did it by having a special package created that incorporates a more useful lens directly into the LED part. This allows them to have a mini mag-lite with an LED that still allows you to focus the beam by twisting the top of the flashlight and thus raising and lowering the reflector.

    The only REAL problem inherent to LED lights is that they are expensive to produce.

    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 if you want something truly bright, you'll find you have problems with heat dissipation.

    For those who like truly ugly AND wasteful (but retro!) lighting, try an uncoated, self-ballasted mercury vapor lamp. 160 watts and slightly less efficient than a standard incandescent.

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.

Australia bans incandescent bulbs, California starts talking about it -- and if it snowballs across the nation, suddenly GE's looking at writing off whole factories and a couple billion dollars. At that point, ethics go out the window.

    So someone in the PR department calls up the head of whatever R&D department they have left and says, hey, do you have anything we can use to make a case that banning incandescents isn't justifiable. So some proposal which was too costly and was sitting on the shelf suddenly becomes the subject of a media blitz, even though it's best case vaporware, worst case FUD.

    The trade press etc is full of all kinds of hype suggesting that there are silver bullets: "Use Product X and all your development problems will go away". The good engineer is no more fooled by this than the Good Housewife believes that Brand X detergent really gets your whites whiter than white!
