They are mostly for fun and not even the most powerful lights I own. Ever thought to yourself I wonder what that is 1km away well with a K1 you’ll light it up like it’s daytime.

I have only been collecting like a year or so and never had to use my lights in an emergency.

The sbt90.2 is a monster of an led but also costs about $50 extra and eats batteries.the sft70 with boost driver isn’t as bright but will run at full power for hours unfortunately the manufacturer doesn’t offer this combo I had to order it and add the led myself

I have posted some pics to /r/flashlights
