Query: Short Life Span

They don't outlast 8-10 incandescent bulbs as claimed. My experience they last about the same. I swapped out my entire house last summer, about 40 bulbs altogether, 5 are still working. So I'm back to using incandescents. I do recall ever replacing so many burned-out bulbs. I'm all for saving energy but more work on the technology needs to be done before I jump in again.
