Actually the lamps I'm using are also probably Chinese - what cheap electronic geegaw isn't these days - but mine are hanging tough. Maybe you need to purchase from a bigger name, one that exacts a bit more quality control over the product.
The spots and floods in the peak of the chapel, placed there because a 50,000hr lifespan looked awfully attractive when the fixture is 35' from the floor, are good. I've had one die and I'm not renting a lift just for one lamp. There's about 19 more so we're still good.
The Home Depot-sourced floods in the lobby are in good shape, most are over a year.
All my LED lamp installations at work have been Phillips brand, with a few Lithonia brand for the outdoor fixtures.
