I look at my lights as tools, not collectables. For me I'd have a hard time buying even two flashlights that have mostly overlapping functionally.
I hope your collecting them because you like them, and not as an "investment". Other than in some rare cases, technology tends to go down in value, not up. I imagine that 5-10 years from now people will be saying, "They only got 200 lumens for 2 hours out of one set of batteries. . Can you believe that!!"
Now that you have all these lights, what are you going to do when the next gen, or the gen after that comes out, that makes the current lights look like cave dweller technology? Replace all of your lights? Open an LED museum? :thinking:
