It means that 25 hours is the expected (not minimum) lifetime. YMMV depending on actual voltage supplied, how much you shake it while lit and random differences in manufacture. Everything screams before it dies, and incandescent get hotter just before they burn out.

Does this mean the bulb will burn out after 25 hours or just that they can no longer guarantee the color temperature after 25 hours?
