GE hopes to initially offer 2x the energy efficiency of incandescents and ultimately 4x the energy efficiency

The incandescent light bulb has been coming under fire from two sides in recent times. On the one side, we have LED lighting looking to encroach into incandescent territory with brighter light and drastically reduced power consumption. On the other side, we have seen that fluorescent technology is being embraced increasingly by consumers.

General Electric (GE) hopes to fight off its rivals with a reinvigorated incandescent technology. GE's Consumer & Industrial’s Lighting division is developing an incandescent light that boosts the energy efficiency to near-fluorescent levels. GE also claims that the increased efficiency will not come at the expense of brightness, color and light quality.

"In addition to offering significant energy savings comparable to CFLs, the 21st century version of Edison’s bulb provides all the desirable benefits including light quality and instant-on convenience as incandescent lamps currently provide at a price that will be less than CFLs," said Kevin Nolan, VP of Technology for GE Consumer & Industrial. We and other lighting manufacturers have been aggressive in developing and marketing CFLs. But consumers want more options and we plan to respond to their needs and deliver environmental benefits, too."

The high efficiency incandescent (HEI) bulbs would replace current household incandescents ranging from 40 to 100 watts. The initial HEIs are expected to be at least two times as energy efficient as traditional incandescents. As the technology progresses, GE is targeting four times great efficiency which would make it comparable to fluorescents.

I'm worried about the color of these bulbs. Even though these incandescents are more efficient and cheaper than previous incandescents, they're still going to have a hard time encroaching on the efficiency and longevity of compact flourescents. I'm sure the competition will be good and will drive CFL makers to build CFLs even better and cheaper, but if incadescents of the future are going to suffer from the same problems as CFLs (bad for spot lighting, recessed lighting, etc.) . . . I'm not so sure I would buy these new incandescents.

According to this article GE claims that the light quality is the same, but looking at the pictures I've see online of these bulbs, they look a little bluish.

The picture in this article is a standard "reveal" incandescent, which GE intentionally adds blue to the glass, in order to produce a slightly more natural spectrum.

I don't know the details on these new incandescents...but the only way you can possibly increase the efficiency of that technology is to raise the operating temperature. That's going to have the effect of making the spectrum close to that of the sun, so I think quality of light would be the least of the worries. Cost and bulb longevity, now, may be real concerns.

The color of the sun comes from its surface blackbody radiation temperature of ~6300K. Current incandesent light fixtures operate anywhere from 2000K-6500K. So we are already at/near the sun's spectrum. Increasing the temperature would shift the light "bluer" and while there is more energy at higher frequencies, I don't think that is the only way to increase efficiency. Modifying the filiment, such that it has higher resistance, yet still emits radiation in the standard range will reduce current demands, and hence improve efficiency.

On a side note, many applaud flourescent lighting but one thing has been absent from discussion. Flourescent lights affect the power factor of the incoming power, so do not actually conserve power. The higher lumens of CF's, however, require a smaller wattage bulb compared to incandescents.

Correcting the power factor does not save any power, at best it only lowers the VA by lowering the VAR (VA Reactive). As long as one's power meters actually measure watts, there would be no difference. Power factor correction (even in PC's) really does the user no practical good at all, it's really only an issue with commercial concerns with large usage of poor PF devices (most of a home's usage would be things like electric stoves and water heaters or electric dryers where the power factor is "perfect"). Having poor PF's, in terms of power lost, only is in the wire-losses in the cabling where the I^2-R losses increase a little -- and that's more an issue for large currents and high percentage of total use. Losses in home wiring is small compared to the power used by the light bulb (in these examples) and the PF's increase in the wire losses is a tiny portion of that already small number.

A standard tungsten incandescent bulb filament operates from 2000-3000K. There are specialized high temperature ones which operate above this range...but those are already more efficient. I imagine GE is simply trying to bring that technology down to the residential market.

> "I don't think that is the only way to increase efficiency.."

It is. Efficiency of a tungsten filament is a direct function of operating temperature, via Planck's law of blackbody radiation.

While I don't disagree, can you tell me which law of physics mandates using tungsten filaments, which was my original point. Research on other materials/alloys/composites may increase the efficiency while at the same temperature.

You miss the point. Other materials may indeed be more efficient. But if they are, it will be because they operate at a higher temperature.

If you're generating light through a hot element, then its spectrum will be determined by Planck's Law. And that spectrum determines its efficiency. Incandescents are inefficient because they radiate most of their spectrum into the infrared. The only way you change that is to increase the temperature.

The picture is of a current GE Reveal bulb - they are deliberately bluish to cool down the colour temperature. Sorta like the blue-bulb headlights.

Regardless of that, it seems that the hope to get to incandescent efficiency, not that they are already there. Me, I'm all CFL at home now except for those lights that have different bulb bases. Next will be LED - they're not far off from ready to fly at the consumer level. They'll probably be there by the time GE can make their 4x efficiency bulbs.

LEDs should be great in terms of efficiency and longevity, but they ones I've seen in person tend to be bluish and dim. They installed some in the recessed lighting in the elevators where I work. They're not as good as the old incandescents they had in the elevators previously. I'm not a big fan of those LED lamps, but the ones they put out for consumers will probably be better.

There are low color temp white LED's being made now. Early ones used to be more blue (higher color temp). If you find an LED based bulb, make sure you check or ask about the color temp. Something around 4000k is considered warm and around 7000k is cold. You can find all sorts of LED based replacement bulbs on ebay, but they are more expensive than CFL's and have a way to go on the price for them to be competitive ($/watt). LED's are something like 90% efficient at producing visible light and last a long time. As production is ramping up around the world, we'll see more LED based bulbs on the market. Hopefully in a few years!

Nowhere near. The best commercially available LEDs run about 75 lumens/watt. That's worse than the best fluoresecents (100+ l/w) and far worse than sodium lights, which can hit 200 l/w.

The theoretical maximum is ~680 l/w, so LEDs are still only around 10% efficient.

Yes, but they are more expensive and less efficient than the standard B+Y white LEDs.

I've run tests that showed otherwise. I don't know what LED's you're using for the numbers, or what the lumen distribution was, but something is missing. We found LED's to be more efficient that the best CFL bulbs. I noticed you didn't say CFL but just Fluorescent, and that may be a differing factor.

I might also ask if you're using commercially available lamps for your numbers, as I've seen some pretty impressive lab results that just didn't pan out in real-world testing.

It is. CFL bulbs average around 50 l/w, or less than half what standard fluorescent can do. Still, most white LEDs are below even CFL, though a few commercially available variants can best them.

Nichia recently developed a white LED which produces 150 lumens/watt, making it as efficient as sodium lamps. Cree and Lumileds both claim to have produced LEDs around the same level of efficiency. I don't think either of these are being mass produced just yet, but I wouldn't be surprised if they are by the end of the year. All these LED manufacturers have made big jumps in the efficiency of their LEDs in just the last year alone.

The ~50 lumens/watt for CFL seems consistent with what I've seen online from the manufacturers. I think the long fluorescent tubes come in around 80 lumens/watt.

Not quite. LP sodium lamps can break 200 l/w...though these have even worse spectrums than white LEDs.

A T5 tube can exceed 100 l/w.

All you have to do is overdrive the voltage and the lamp gets energy efficient - for a very short time.

GE, Sylvania etc... have a LOT invested in plants to make incandescents that they'd like to keep using. If everybody replaced their old bulbs with compact fluorescents, that would hurt big time.

Nice open-minded view - NOT!

If GE can hit the same efficiency as CFLs as they claim they can, and at a lower cost, then I for one would be pretty interested. After all, what is so special about CFLs? The only reason to use them over incandescents is the efficiency. In other aspects, people seem to generally prefer incandescents - color temperature, flicker (real or perceived), start-up time, etc. Also, since CFLs require an electronic ballast, they will almost certainly always cost more than an incandescent.

Good points as usual, TomZ. Even if an incandescent was almost as efficient as a CFL, it'd be a better environmental choice, due to the much lower amount of materials used to construct it.

What is so special is that they evolve too, color temp and flicker, start up time are negligable and beyond perception in many cases.

What remains is whether the intended use would be similarly efficient at similar cost, including the all-important lifespan factor.

I say good for GE to make these, because in a few years some knock-off will be nearly as good for a much lower cost. For what they are, name-brand incandescent bulbs cost too much as it is, especially the floodlight types. Give me a good CFL alternative floodlight for all my recessed lighting needs and I'd have no need for any incandescents anymore except outside.

You're forgetting the one factor that incandescents don't beat flourescents and that's maintenance costs.

The average lifetime of a CFL is many times that of an incandescent which means not only less changes but also paying people less to change bulbs. In really difficult places that puts even the elevated cost of LEDs into commercial range ie. stoplights.

My latest addition is a 27 watt full spectrum CFL and lamp combo for reading. It is very bright, I can put my hand on it and not get burnt. An incandescent at half the brightness would be uncomfortable over my shoulder due to the heat.

I'd expect pricing positioned between the two, a little more expensive than a traditional incandescent but due to lower complexity, cheaper than fluorescent.

The other factor is whether the lifespan is the same (as CFL). I doubt that, but admit I was too lazy to read the article yet. :-)

I don't see the drawbacks in CFL though, turn-on is fast enough, color on decent bulbs is a lot better than it used to be. Mainly I see the problems as a higher susceptibility to fire if poorly made, and less resistant to temperature extremes.

I expect with high enough volumes, the learning curve will allow them to get cheaper though I doubt it will be at the rate of CFL's which can be bought at the dollar store these days, esp since normal incandescents are still around and very cheap.

Other conditions I would like to know is the life expetency especially in continuous on/off cycles which is the only place I use incandescents anymore and high moisture areas.

Anyway, good for GE trying to improve it's product. Nothing like the threat of losing market share to "light" a fire underneath a company's proverbial rear.

They only flicker because humans are too cheap and lazy to clean up the power to them. The noticable flicker is at twice the line frequency (120 or 100Hz depending on locale), and could be done away with at higher expense, while CFL's typically use an electronic ballast which has a much higher frequency, so you wouldn't generally see that flicker.

The CFL's I've used (as well as non-compact fluorescents) don't last anywhere near as long as they're "supposed to" when used in applications where they are turned off and on a lot (incandescents don't have this problem, despite what the old wives tale says). Packages will have asterisks showing the conditions of the expected longevity and the "on time" is pretty long there. We've some on automatic motion turn-on (like in closets) and the like and they don't last long there. For those uses, a 10,000 hour bulb should last nearly forever (never on for more than maybe five minutes a day total, in several sessions) but they'll have to be replaced every few years anyway. Ones that are on for long periods of time do much better.

I know of 2 incandescent technologies that can enable a higher efficiency than the regular incandescent bulb.

#1 - carbon nanotube bulb. This is just like a regular light but except the tungsten is replaced with carbon nanotubes. CN is super tough so it can withstand a higher temp than tungsten.
#2 - nanotech tungsten matrix. A cube of nano lincoln logs made of tungsten is constructed so that the spacing between logs is less than that of infrared. Infrared from inside the cube cannot directly escape so it is reabsorbed. Some of that energy to come back as visible light, most will come back is IR. Still more efficient than a regular bulb though.

I also guess that it would be possible to combine these 2 technologies.

It seems that some folks here assume that as GE takes time to introduce these bulbs and then takes the additional time to get them to "nearly" be as efficient as fluorescents that the other industries will remain stagnant in their technologies. The CFLs of today are far better than just a few years ago. LED lighting is improving constantly with improvements in brightness and spectrum. Costs for both are dropping and will continue to drop as they are improved. As are any of the high end incandescents (long life, special coated), I bet the price on the new GEs will be pretty salty.

Mercury content

The presence of mercury in CFLs (and standard fluorescents) never seems to get mentioned as a potentially large negative to such proliferation of this lighting technology. The mercury recycling infrastructure for these bulbs isn't sufficiently built-up in the majority of the North America to support the large influx of these bulbs. Recycling of commercial tubes is a bit easier to handle, but this is a separate environmental disaster in the making...
