The cheaper, low quality diodes don't last as long as the, better, high quality diodes. Some diodes will last 50,000-80,000 hours MTBF but even LED diodes lose intensity over the life of the light. That doesn't mean that every diode will last that long, it's just an average or sometimes it's even an estimate.
