Would you even bother trying to get a refund on a $12 lamp after "only" ten years of life? Manufacturers should definitely change their stated lifetimes if the

  Yes I would! I could have bought a $5 lamp of comparable efficiency, and also have had ten years life; I specifically paid more to get the longer life, damn it! :) Maybe the vendors are banking precisely on your thinking; that people in the future will lose their receipts, forget the dates, or consider $12 from ten years ago a trifle matter that isn't worth their time and so on, and yet that people can be conned into coughing up more cash today. By the way, how long an LED lamp will last depends on multiple factors. It's not just the silicon itself, but all of the components in the complex power supply that is integrated into it. It could be zapped by a power surge. (Do these things incorporate TVP's?) Notice how no electronic appliance that you can buy claims to be good for 25,000 hours of continuous use. No smartphone, no television, no home theatre receiver, no computer. Typically you get a 1 year from the date of purchase, whether it's used or not and you can pay extra for more coverage. One year gives you a little over 8000 hours if you fire it up right away and leave it on continuously.
