Why did my 10,000 hour energy saving compact fluorescent lightbulb stop working after less than 5,000 hours?
I don't think I realized my promised energy savings.

Don't believe what they're saying
- ... some of the gems in the blogosphere, such as ... Environmental Economics
-- Economic Way of Thinking - First I must say that I have found your blog to be a fantastic read. My colleagues and I actually laughed out loud at some of the posts!
-- UKNEE - Environmental Economics offers broad and shallow comment on that field, with an emphasis on valuation, climate policy, transport, and beer.
-- Aguanomics - The charming dorks at Environmental Economics point out ...
-- Lisa Margonelli - If I could only read two blogs each day they would be Environmental Econ and Environmental Capital.
-- Rich Sweeney - Excellent post, and a rare one on your site without any snark, sarcasm or puerile humour.
-- The Olive Ridley Crawl - Checking your blog is the highlight of my morning (well, unless I missed The Daily Show the night before, then you run a close second behind catching the missed episode). So, who needs the public affirmation of high rankings when you've got hordes of loyal readers?
-- Meredith - Are you sure you guys have econ PhDs? Something doesn't fit.
-- Bob Murphy - I can't believe you're an economist. Fantastic.
-- B Madsen - John Whitehead = HILARIOUS!
-- Mark C R UK - ... explains the mechanics of things with numbers and reason and insight. Don't be intimidated by the economics angle. It's never abstruse or technical. Instead, the tone is straightforward and forthright, at times bracing or breezy.
-- The Suzuki Foundation Blog - 10 Interesting Economics Blogs
-- Milken Institute Review - These guys have the self-confidence to call their blog simply 'Environmental Economics', and rightly so.
-- Oikos - ... [a] surprisingly entertaining site about economics.
-- Bottleworld.net - "... the refreshingly accessible 'Environmental Economics' blog"
-- American Institute of Biological Sciences - I'm not an economist nor am I a genius, but what you state is so glaringly obvious I don't understand why the vast majority of Americans don't get it.
-- Fritz - ... the Environmental Economics blog ... is now the default homepage on my browser (but then again, I guess I am a wonk -- a word I learned on the E.E. blog). That is a very nice service to the profession.
-- Anonymous - "... I try and read the blog everyday and have pointed it out to other faculty who have their students read it for class. It is truly one of the best things in the blogosphere."
-- Anonymous - "... the best environmental eco blog on the web – regular, informative, entertaining."

"I don't think I realized my promised energy savings."
Worse, you likely also forced your utility to have to generate more power than you thought it took to light that lamp of yours!
But, back to the problem at hand, there is that whole problem of large numbers of shoddy CFLs being produced, mainly for the sake of getting the cost of the lamps down to a level where consumers will choose to buy them.

"I don't think I realized my promised energy savings."
Yes, but just think about all the Green jobs you will be creating when you are out buying a new bulb.

If something sounds too good to be true, it usually is.

Thank you for posting this question - it's a prime example of the short term thinking, stop-gap solutions our wonderful government (all levels) dishes out.
- points above are certainly valid.
- CFL's have a "life span" issue if you cycle them too often (on/off)
- what will you do with the mercury from your old bulb.
Since you are aware (most likely) these are hazzardous waste...you'll probably take them to a proper disposal facility.
How many Americans are just tossing them in the garbage? We'll soon have issues with Mercury leeching into our water supply.
I still think these bulbs are a good idea if you properly match the bulb to the application....but, they're no silver bullet.

How do you know how many hours it ran? did you have a timer on it? Was the circuit overloaded and below voltage? Was it in a location it is switched on and off frequently? Was it on a dimmer switch?
Any of these will reduce lifetime.
