content: My favorite was the ENDLESS replacements I kept getting for free, from Phillips, because they'd burn out within a couple months (1 year warranty).  I started writing the date on the base, 5 weeks was the shortest one with Maybe 20 hours. But they kept sending more, always.  I even got to the point of having a direct email contact with one of the CS supervisors/managers. I finally got tired of it and bought incandescent again... which is most of what still lights my house today (2 or 3 LEDs to try them, worlds better than any CFL).
