Some of the bulbs I have purchased only lasted two weeks at no more than a couple hours use per day. Very disappointing (maybe 30 hours lifespan). I am a big fan of LED lighting. Choose a bulb that fits the application (lumens and color) and you will be happy. Unfortunately many manufacturers and vendors overstate (I'm being kind here) their products specifications. I have purchased 45 LED bulbs and have had mixed reliability. The good news - some are very reliable. I have five LED bulbs outside that have run dusk to dawn for two years with no problems. The bad news - some bulbs are VERY unreliable. VERY high failure rates. I purchased 12 of one type LED bulb and 12 out of 12 have failed (8.5W product 47856 from LEDLight.com). 100% failure rate. To make matters worse they are refusing to replace them now. Beware of LEDLight.com. This company is selling products that they know are defective. No support for failed LED bulbs. These bulbs are very expensive ($20 - $105) and in some cases last only two or three weeks. They refuse to replace defective bulbs. LEDLight.com is selling known defective products and has bad customer service. ledlight.com, LED, problem, fail, failure, burnout, quit, reliability, unreliable, review LED bulb reliability – HIGH FAILURE RATES

I thought they weren't used in things larger than dorm fridges due to inefficiency. As far as I know, most other countries still also use Freon-based cooling technology, at least for homes and cars. Larger scale cooling uses amonia and other mediums. @phil – Can you please provide a reference for this US ban on Peltier junction devices.

It's not as hot as some places, but it's hot enough, long enough for air conditioning to be a much bigger power consumption issue than lighting. There is a huge push to adopt lower-power devices for lighting but almost no push to adopt any kind of air conditioning system improvement. When the U.S. drops it's ban on solid-state coolers (Peltier junctions) I will start considering spending money on improving the power consumption efficiency of my home. (note, you can get junctions, but they are small and most usually incorporated into an existing product.) And before you jump me for being an electricity waster, my electric bill for the last 11 years has been less than $200 -any- month of the year, and most months much less than $100 and I live in a 30 year old, 2200 square foot stick-built house.

So your 60 watt bulb is basically a 50-some odd watt heater. The amount of CO2, particulates, and mercury, emited during the generation of this excess current are its main problem.

They are highly evolved and offer consistent light for the lifetime of the bulb. And you can get four for a buck or so. They are extremely important in many industries, which is why they will be around for a lot longer. CFLs are expensive to produce, contain mercury, and are very dangerous when they explode (which happens often when they get to the end of their useful life, at least in my experience). They spew mercury vapor into the air you breathe. In many places, it's illegal to throw them away but household recycling won't accept them. You have to drive your incredibly inefficient internal combustion engine to the nearest Home Depot or Lowe's for recycling (or do what I suspect most people do: wrap them in newspaper and toss them in the trash). Compare this to a normal incandescent bulb: the glass will break down back to sand, the metal used will rust away, and all is well with the world.

I'd like to point out that trying to find an equation which includes electrical usage, component fabrication/creation, and final construction has been beyond my capabilities to research. For example - an LED (as I have noted) uses an artificial saphire substrate. That artificial saphire should require formation in a 3000 degree plus electric oven maintained for 7 or 8 days. What I haven't seen is just how many substrates are created for individual LEDs. I have a hunch that a simple 75 watt incandescent bulb is almost nil (relatively speaking) an energy expenditure to put together. And it contains nothing of the environmental significance that the mercury in a flourescent does. Couple that with the real usage of fixtures in the average 1600 sq. ft. home and you are not gonna save anywhere near enough in our homes to offset the huge waste in New York and Chicago as empty skyscrapers are lit up (inside and out) throughout the night.

You don't mention the actual watts consumed by the bulb; you don't mention the lumens of light output; you don't even compare the light output of one LED bulb with that of a 100W incand. bulb. These are essential facts. I can calculate all by my lonesome the cost per year IF I know the actual wattage consumed by the bulb. Let's improve the fact presentation.
