My friend and I are curious about the lifespan of LED's. I have read from several sources that led's get dimmer overtime, whereas my friend thinks led's remain a consistant level of brightness pretty much right through their life until nearly the end.
If they do in fact get dimmer.. at what rate? will they remain 100 % bright until the last few hours of their life at which point they will rapidly get dimmer and cease functioning.. Or do they gradually get dimmer over time, so for example an led light with a 10 year life, after 5 years will be 50% as bright.
I would appreciate any answers (along with proof) that you can find.
Thanks
Anthony.
