Yes, but how often to your usual light bulbs fail when they have been on for a while, they usually break when they are initially turned on. I wonder how these eventually fail.
This particular LED has 50K hours of burn time (5.7 years of constant use)..
A bigger problem (at least they are honest about it
“Remember: LED lights are directional (like a spotlight). This EcoLED light has a beam angle of 100 degrees, which is equivalent to a wide spotlight. It is not appropriate for use in lamps with lamp shades or other lighting applications where light needs to be emitted in all directions at once. (However, it can be aimed at a wall or ceiling to produce radiant ambient light that radiates through the entire room.) Also note that this EcoLED product produces clean, bright “white” light, not the typical yellowish light produced by incandescent bulbs. Most people agree that our white lights offer far better visibility and clarity than common yellowish light bulbs.”
LEDs get dimmmer over their lifetime, especially if they are driven hard.
