I have several reasons. I work outside & camp quite often. Love the new technology as well. These new lights out are just amazing... My whole deal on collecting lights? I guess it boils down to this.. I like collecting things that are useful.. First it was leatherman multi tools... Well, there are only so many leathermen you can collect. The flashlights are much more plentiful & useful. Some people collect stamps, matchboxes, etc etc... Not that there is anything wrong with that. I just prefer my collections to be able to be utilized. Some where along the way I started learning about lumens, Lux, throwers,flooders, different emitters, the list goes on & on. The great thing about lights? You can find all different kinds in all different price ranges... From very expensive search lights to very inexpensive pocket lights. SO it even fits your paycheck... Weather you plan to spend hundreds, or just five or ten bucks.
