..and that is cheap!

Any comments on life? Output?

The manufacture claims 4,000 hours. Compared to conventional filament lamps,
you should get twice the light output and four times the life.

Dubious. For a halogen, you can design for higher light output
colour temperature and efficiency, or for longer life.
You can't get both options together, at least nowhere near twice
the light output and 4 times the life -- those figures aren't
even available separately.
