Acquaintances that follow my hobby and love of flashlights have never been overly impressed with the lifespan of my LED lamps. When shown a new light though, one of their first questions is "how long does the battery last on that one"?
When showing my LS lights and finding they haven't much more impressive battery life than an incandescent, most just remark "yeah, that's bright".
I'm not convinced those that haven't grown along with the advances of the LED is impressed with simply approaching and matching light output with incandescents. Other than the technological advancement, I'm not so sure I am either.
