The newly-introduced Pharox bulb from Lemnis Lighting uses only four watts of energy compared to seven watts used by a CFL bulb, and emits 2.69 kg of CO2 compared to 4.70 kg emitted by a CFL bulb. The Pharox bulb contains no mercury so it is entirely recyclable, lasts for 35 years (at 4 hours a day) or 50,000 hours, does not get hot, and emits a soft warm glow./////snip/////If one percent of the earth's population were to replace just two incandescent bulbs to Pharox bulbs each, then we would save about://////- 6.3 billion KWh of energy//////- 100 million tons in CO2 emissions//////- $35 billion in usage/replacement costs.//////end of excerpt.////Imagine that. Buy a bulb, save the world... or at least do something to atone for the damage we have already done to this planet.

  • Cool. Can we buy them at any store or are they being sold exclusively? Also, are they a lot more expensive than regular light bulbs?

  • http://www.lemnislighting.nl/partners.html This is the link noted to order http://upscalelighting.com/subcat.php?did=1&catid=1... $59.00 per this site. A bit more than I thought but it's in the introductory stage so maybe the price will go down. Hopefully they will also be more widely distributed.

  • That is a bit pricey, but if it lasts 50 years the cost per year isn't so bad.

  • I think the problem with the price is a lot of people have trouble seeing the long term (financial) benefit of buying energy efficient products. It may be that they save money in the long run, but not everyone can afford to buy a $59 light bulb.

  • we are about to see a lot of bulbs like this in upcomming years due to the fact that congress passed a bill making the sale of incandescent lights illegal by 2014

  • blockbuster, do you have a link to the bill you cite?

    $59/bulb makes it boutique lighting. Good to know the technology is there, but until we take the money we give to oil companies and use it to subsidize light bulbs and other energy-efficient technologies or practices, the price makes it irrelevant.

    Look, Ma, I bought six light bulbs with last week's pay check! Aren't you proud of my investment acumen? Not gonna happen.

  • Like any new technology, the upper class will pay the higher price first. That pays for research and development. As more and more are produced and competition enters the market place, the price will go down.

  • hooray for innovation!

    we can be skeptical (as we should) of how companies could conceivably disregard ethical practices to maximize profits, but this looks like a step in the right direction.

    now, if we can convert our lightbulbs, i'm sure we can convert our cars (to electric)

  • I like this and I have another idea:

    It is often said that the three rules of real estate are location, location, and location, but what if we could change that to location, location, and energy efficiency. Imagine if energy efficiency became one of the important criteria in purchasing a home. We view energy efficiency as important in purchasing our automobiles and many of our household appliances, but not our homes.
    I would suggest we begin to change this by requiring all homes when they are placed on the market for sale include the results of an energy audit. Now clearly this requirement would have to be phased in over time, but if home buyers could use energy efficiency as one of their criteria in determining which home is most suited to their needs, than more homeowners, and homebuilders would be motivated to increase the energy efficiency of their homes.

    This simple change would have many beneficial results not the least of which would be the tens of thousands of new high tech jobs retrofitting and constructing energy efficient homes. New jobs to teach energy efficiency, new jobs to identify and build energy efficiency, new jobs to supply energy efficiency materials, and the list of the potential increases in employment opportunities goes on and on.

    As homes increased in value because of their energy efficiency, more homeowners and builders would decide to invest in improving their homes efficiency, but, of course, the real benefit of this change would be the decrease in energy demand, and the subsequent reduction in our planet harming habits. I would hope that the increasing price of energy would moderate, and our economy would be greatly strengthened with this increased attention to home energy efficiency.
