Does GE make CFLs?

OrenT

I guess they apply some type of nanoscale surface treatment to the filament that suppresses emission in in the infrared spectrum.

I wonder what is the theoretical limit. If you could etch perfectly formed and spaced resonant cavities on the surface what efficiency could such a modified blackbody radiator reach?

Yes, GE makes CFLs: http://genet.gelighting.com/LightProducts/Dispatcher?REQUEST=CONSUMERCATEGORYSUBPAGE&CHANNEL=Consumer&CATEGORY=Lamps&bulbtype=Lamps_Compact%20Fluorescent

"The real issue is, if we don't do it, someone else will," says GE's ecomagination vice president, Lorraine Bolsinger, of Wal-Mart's effort to push CFLs. "It's old thinking to imagine that you can hold on to a business model and outsmart the consumer. You can't."

I love the efficiency of CFLs, but not the slow warmup of some models. Nor the mercury. If HEIs are for real, bring 'em on. They may do the trick 'til LEDs mature.

Let's try that again:

Sounds good to me. As usual, capitalism will do more to benefit the environment than all the left wing pot bangers rolled together into one greasy ball.

GE apparently announced this technology at this particular time because of concerns that the various state & country initiatives to "ban the incandescent bulb" would do just that, rather than setting efficiency standards and leaving the technology choices open.

What if the HEI(tm) technology had been invented by a startup company, rather than by GE? Such a company would have had little ability to influence legislation, and might well have been confronted with a wall of "no incandescents" edicts that would kill the technology in its cradle.

I'd like to hear what GE's solution is for the other environmentally beneficial aspect of CFLs and LEDs. Long life.

Sounds like this is GEs play to get their disposable lighting market back under control.

Too little, too late.

The California legislature hasn't yet voted on the proposed bill. If you are a Californian, I would encourage you to write your legislator and point them to this press release.

It isn't too late for them to fix the wording of the bill to make it technology neutral. Setting an efficiency target is far more rational than banning a specific technology under the now obviously false assumption that innovation can't happen.

You can also contact the author of the bill:

And all that mercury. Yummy!

As usual, right wing ideologues get it wrong. Again we see innovation that benefits society not happening until regulation or threat of regulation.

amazingdrx

As usual "freemarketeer corporatarians" do nothing for anyone. And keep on prattling about capitalism as if they know something about it. What they think of as capitalism is actually corporate feudalism. Monopoly suppression of innovation.

Without corporate monopoly gaming this new bulb might already be in full production, but GE had to sell their old incandescent bulbs as a top priority. And now their CFLs.

Real competitive capitalism would have solved our energy crisis decades ago, after the first oil shock in the late 70s.

We need leadership with the guts of the trustbuster, Teddy Roosevelt, to restore real competition to the US and world economy.

It took quite a bit of looking on the Internet, but I found some technical information on these GE lamps. The "trick" is a coating on the inside of the glass bulb that reflects infrared (heat) back to the filament, but allows visible light to pass through. Thus it takes less power input to run the filament at the same temperature.

This stimulated some dim memories, so I dug through my files. I found a flier for the "Mi-T-Wattsaver" bulb which was briefly manufactured by Duro-Test. It used such a coating. These lamps produced the light of a standard 100 watt light bulb but used 65 watts (and lasted 2500 hours vs. 750 hours). The bulb used exactly this sort of reflective coating. Unfortunately, they were quite expensive. The glass envelope was an ellipsoid made in two halves, joined together. I am certain this was costly.

I often think that everything can be found on the Internet, but I found only a brief mention (and no technical details) of this bulb at a Smithsonian website when I did a Google search.

donb -- I'd be interested in seeing an image of the flier you found for the Duro-Test lamp. If you can and don't mind doing it, please send a pdf to jdmitchjr@comcast.net. I have some technical information about the lamp I can send you in exchange. Thanks.
