LED light source projectors are rated as lasting 15,000, 20,000 and 30,000 or more. They have been around a while now so I'm sure some of you have put many hours on them.

Could you share your experience with longevity? Have you noticed any change in brightness?

If you don't mind including:
the maker,
the highest rated lumen,
how many hours you have on it,
Whether you mostly use it in Full or eco mode.
