Are you saying that LED's put out less light after six months? That's the first I heard that.
Actually, I experienced this big time. The fall before last, I invested in some 15 x 15 = 225 LED grow lite arrays to keep my potted dwarf lemon trees 'happy' indoors through my northern NY winter.
When I moved the trees indoors for this winter, and I also added a couple of identical but new 225 LED array for additional trees I recently acquired , there was a HUGE difference in lumen output between the old LED arrays and the new LED arrays.

I saw some lightbulbs at the local conventional grocery store. They looked exactly like incandescent, but they claimed to put out 20% more light. The box was covered in marketing, but I couldn't figure out how they were doing it. It just seemed like a regular light bulb.

40-80% of most peoples environmental damage is due to the dirty energy use of homes and buildings. You mention 7% of this being form Lighting but for some its 25% and I think an accurate average is 12-15%. In high performance homes, Lighting with incandescents could easily account for 40% of the homes energy use.
Regulate home lighting because its the lowest hanging fruit available.

The simple question to ask, for a neutral observer,
is why the major manufacturers welcome a ban on what they can or can't make!

Maybe some of you know french!

Ok the light in the fridge can be an LED light. I don't think that LED's run well at stove temperatures. Nor do they make good porch and garage lights even at 0 F....

Many of these state efforts became moot when the federal government enacted the Energy Independence and Security Act of 2007 in December 2007, requiring all general-purpose light bulbs that produce 310–2600 lumens of light  be 30% more energy efficient (similar to current halogen lamps) than current incandescent bulbs by 2012 to 2014. The efficiency standards will start with 100-watt bulbs in January 2012 and end with 40-watt bulbs in January 2014.
Light bulbs outside of this range are exempt from the restrictions (historically, less than 40 Watts or more than 150 Watts). Also exempt are several classes of specialty lights, including appliance lamps, "rough service" bulbs, 3-way, colored lamps, and plant lights.
By 2020, a second tier of restrictions would become effective; which requires all general-purpose bulbs to produce at least 45 lumens per watt (similar to current CFLs). Exempt from the Act are reflector "flood", 3-way, candelabra, colored, and other specialty bulbs.

I was not aware of all the exceptions. Thanks. Exceptions make for bad law, IMNSHO
A better way to do this sort of thing is taxing it rather than regulating it. Tax at the source -- the light bulb maker -- easy to collect (there are only a handful).....
paul wheaton wrote:Rather than ban or tax the best, cleanest and most eco friendly bulb on the market (the incandescent), how about if the government looks into ACTUAL energy conservation instead of making-somebody-rich-in-the-name-of-green?
If the focus is on lighting, how about making consumers aware of stuff like turning off the lights when not in use. My experience is that the only people where switching to CFL can possibly save money is where they have lights they are leaving on 24x7.
Next up, rather than going over something that uses 7% of the home energy consumption, how about a little focus on the thing that uses 50%: heat. In my article about micro heaters, if just a few people actually adopt that then the savings will be far greater than anything that the light bulb stuff even claims to be.
Either of these paths require zero laws. It is just passing along some information.
