how long does a LED last. I'm looking at a
 
I was wondering how long a LED TV lasted. I'm lookin a a floor model Sony 55 KDL55EX620. Sears has it on clearance for $839. Im just concerned that it has been on for display for 7 days a week from 10am to 9 pm. Any opinions??

The half lifes for flat panel displays nowadays are in the ten thousands of hours or pretty much on 24/7 for 15-20 years before you would see a picture dim. Short answer - much, much longer than you will probably keep the tv or else before something else may break- i.e. power supply short etc..

But it depends, mine LED stopped working in 1 year

You will never know how long any particular product will last. (well, unless it's Toyota :D)You'd have to pull out the good old crystal ball to know for sure.;)

Normal half life of an LED is 10000 hours, but the LEDs are only a light supply.

There's way too many other components that could fail before a LED gives out.

That is not A-typical, most sets, even 3rd tier sets, last several years.

Get a warranty

The components usually give out before the panel.

Everyone is pretty much correct here. I am a Reliability Engineer by trade and more then likely something else will fail in the pnael before the LEDs go-out....LEDS made it todays makret last anywhere from 30,000 to 100,000 and longer depending on the grade..and that is just the half-brightness spec. Although the industry seems to be moving towards the 70% brightness spec...either way it doesn't matter because..by then something else would probably of failed. Manufacturers like to list this spec to consumers because it sounds amazing and relatively easy to measure but it really says nothingabout how long your panel will last. That comes down to Production Line Quality and how well the Design Team did in designing sub-compoents with enough margin in them to account for shifts in the distributions and grade of the lower level components.

Nope, it all comes down to how much supply chain changed the specs to save a nickle. I'm the design engineer that gets a bad rap because of supply chain!!!

Haha!! I didn't mean to offend you, in your case you may be a great design engineer. However, I have also seen the opposite.

I have about a dozen 110 "mushroom" fixturesin my garage (one of those projects that never got done) and two spot lights. I'd like to convert them to LED or low voltage.
