My Surefires are now relegated to back-up lights.
That is a pretty impressive testamonial. What can you say as to their (the Fenix) durability? I wasn't impressed with the Streamlights.
I use one daily and have had no issues with it over the past 2 years, give or take. I habitually carry one next to my spare mag(s).
Two have been fly-fishing with me in Alaska and were exposed to all the elements of S/E: saltwater, rain, dirt, etc, and the conditions of the back country. Both performed exceptionally well.
I like the various "modes" of the lights as well. To that point, I had to use the slow strobe feature during a downpour in near-dark conditions to guide my two friends to shore on one of our Alaska trips. They were out in the Zodiak when then weather turned ugly - fast. It was dusk, then dark, and I noticed they were way off base on finding our camp.
I set the Fenix on a stump, turned it on slow strobe, and they made an immediate course correction. The rain was so intense that I left the light outside and went into the cabin to build a fire so we all could dry out and warm up.
Sure enough, when they came in they admitted that they were heading to the wrong island. "If it wasn't for this light, we would have been lost."
That's pretty powerful testimony. That specific light is one of my favorites to carry.
I hope this helps!
