I agree that there are not much flashlight enthusiast around, and big box stores can't make profit from selling high-end lights. There are also many more users who is not necessarily a light addict, but still use lights.
But the LedLensers they stock are not cheap either, several large electronic stores here have the X21 on stock, which costs roughly the same as a TK70 or SR95.
The LedLedser P7 is also around the price range of Fenix's LD line or Jetbeams's Budget line.
So I think that if brands like Fenix or Olight could expand themselves they could get some of their cheaper lights onto the shelves of those stores and it would be a benefit for both the consumer and the company.
Before, the only way I could get Leatherman tools is to order online, but recently I'm starting to see the Wingman and Sidekick on the shelves of stores. Maybe some flashlight companies could also follow this example.
