  •  CFLs are a stopgap... waiting for LED to mature (0+ / 0-)

    now those are some awesome lights (tech just has to catch up)... but I did see some LED floods (not decorative like you usually see) at Lowe's last week, so almost there. :)

    •  I don't know enough about LEDs (2+ / 0-)

      to make a call on them one way or another at the moment.

      I never liked fluorescent lights because they gave me headaches, but it was only recently that I found out how toxic they are.  Personally, I've contributed many from our laundry room to my local landfill without knowing how toxic and dangerous they are.

      I just don't understand how in the world the Green Movement would think it a better thing for all of us to turn into MadHatters than to use electricity.  I'd rather turn my lights off than risk mercury poisoning for me, my family or my dogs - dogs that do from time to time manage to take out a lamp or two when they play in the house...

        I am hoping that LEDs are being manufactured in a more ecologically-friendly way than they have been in the past. They are, essentially, a semiconductor and they have had a history of using some pretty awful chemicals in the manufacturing process. Just cleaning the wafers used to involve toxic chemicals that workers were getting sick from and resulted in some drawn out lawsuits some years ago. I seem to recall that the processes switched to water instead of the nasty toxic stuff for some stages of the manufacturing process but they are not, by any stretch, as "green" as one might think. On the other hand, I doubt CFL (or even incandescent) bulb manufacturing is anything I'd want taking place in my back yard either.

        I am hoping that the LED replacement bulbs come in high enough wattages and fit in our existing lamps. Many of the CFLs do not fit (too tall for the harp/shades) and they don't come in higher wattage equivalents for people who read a lot. (And they seem to emit enough EM for my guitar pickups to, well, pick up.) The only LED replacements I've seen were only 40W equivalent (maximum) and were outrageously expensive.

        •  Halogen. (0+ / 0-)

          You can use halogen bulbs for your smaller lamp/harp configurations.  And I agree that it is likely that none of the bulbs are manufactured in super environmentally friendly ways.  The thing about the EPA guidelines for CFLs that bothered me really had to do with the fact that people are using them in their homes and likely really don't how toxic they are when and if they break.  It is one thing to be in a manufacturing plant with procedures and protections systems, but quite another to impress upon a dog or a toddler the importance of not getting near mercury - if you yourself even understand how serious the situation is.

    •  And after LED, incandescent (0+ / 0-)

      Everyone thinks that incandescent light bulbs are inefficient, but that's just using today's filament technology.

      Engineers have already developed metamaterials which do not emit blackbody radiation in the infrared range.  If you use this as an incandescent filament, you have a light that is far more efficient, and without the mercury or need for DC conversion.

      Banning incandescent bulbs because of energy waste is like banning cars because of carbon emissions.  This only makes sense if you don't believe anyone will invent a better one.

      Linking to a news article is journalism in the same sense that putting a Big Mac on a paper plate is cooking.
