ESL — a CRT-Based Replacement For CFL Lights Without the Mercury 348

New submitter An dochasac writes "Everyone knows incandescent lights are inefficient little space heaters which happen to convert 5% of their incoming energy to light. Compact Fluorescents (CFLs) are more efficient, but they contain toxic, brain-eating mercury and emit a greenish light. LEDs are also efficient and last longer, but if their blueish 'white' light doesn't mess up your melatonin balance, their price is high enough to wreck your checking account balance and give you the blues. A company called Vu1 has come up with something called Electron Stimulated Luminance (ESL) lights which claim to solve the mercury and price problem with a light based on Cathode Ray Tube (CRT) technology. These lights have the warm color balance of incandescents and are compatible with dimmer switches. The article has further ESL details along with an explanation of why it's still a bad idea to say these are 'trash can safe.'"

    But we're finally trying to improve the lightbulb again. Thanks, energy crisis.

    And don't forget the lava lamps.

    Please, won't someone think of the lava lamps?

    People have been trying to improve the lightbulb ever since it was invented. They have, so far, been unsuccessful, which is why they had to lobby the government to get rid of traditional incandescent lightbulbs, so that they could sell the "improved" bulbs they had developed.
    If they had actually improved on the traditional incandescent, they would not need to have a law passed in order to displace it, people would have switched. Do people need to have laws passed against old computers to get people to buy new ones?

    The LED bulbs I'm using sure seem to be an improvement. But perhaps you're using some metric other then price, quality, efficiency or environmental impact.

    Maybe he wants to use them in his easy-bake oven.

    4-5 minutes? You're smoking some serious grass or something.

    Well put.

    I know I would never buy another CFL if it wasn't for Congress forcing me too (because they outlawed incandescents). CFLs are the perfect example of an "improved" product that is actually worse than what it is replacing. Kinda like Windows 8 or Vista.

    And I suspect if anybody did a study, they'd find CFLs actually use more energy & increase the carbon footprint more than incandescents, because of the extra energy needed to ship them from China & then drive the dead CFL to a recycling center to dispose of the hazardous mercury. It would be similar to how the ACEEE's study showed EVs are no cleaner than a 45mpg gasoline vehicle (and less clean than a natural gas Civic or 88mpg Lupo TDI).

    As opposed to...the energy needed to ship incandescents from China, then drive them in garbage trucks to a landfill site?

    It would be similar to how the ACEEE's study showed EVs are no cleaner than a 45mpg gasoline vehicle (and less clean than a natural gas Civic or 88mpg Lupo TDI).

    Which completely ignores the fact that electricity is independent of it's energy source, whereas natural gas, diesel and petrol are all fossil fuels which can't be easily substituted.

    Increasing energy efficiency lowers energy costs (and makes systems less susceptible to changes in costs), reduces infrastructure requirements (lower costs, more reliable), lowers barriers to entry, makes sustainability possible, increases productivity (more work per unit energy), and allows increasing density of technology.

    Laptops and iPhones would be impossible with people like you at the helm, because "throw more watts at it" does not lend itself to miniaturization too well.

    We can (and should!) still work on fusion energy, meanwhile increasing efficiency across the board will reap more immediate benefits for everyone at every level of society. Ever observe a bacteria colony in a petri dish? The colony grows and grows, consuming more and more, until they run out of resources... then the entire colony dies. I'd like to think we're smarter than bacteria and can at least recognize the consequences of consuming without regard to this planet's limits.

    And of course now you are going to have to continue to experiment with various bulbs and, in some cases fixtures, until you can find some combination that meets your needs. All because some people decided they knew better than you what you need and what was best for you.*


    *this post is not aimed at the poster I am replying to as much as it is aimed at those who think that this government intervention in the market is a good thing (or any government intervention).

For God's sake, stop researching for a while and begin to think!
