LR35R Real Life Review

At first glance holding it in my hands, it's smaller than I thought it would be and also heavier than anticipated. But overall it feels good in my hand as typical with Fenix Flashlights, it fit good in my hand without gloves and for the most part with gloves on. I live and work in Southern California, Orange County so if I want to get out into the wilderness I need to travel at least 2 hours (min.) to get out to nature. With that said I live in a concrete jungle, and that is the reflection of this review.
The LR35R is a super bright, super wide LED Flashlight, but for those who need to know, a not so deep light. I could see this being a great light for the occasional Urban Search & Rescue person. Someone who has the LR35R in their backpack for that one special purpose of Search & Rescue of a person. Other than that realistically I don't see a real purpose for this light.

Great range of Lumen output from 50 lumens to 10,000 lumens, Sturdy clip to attach the light to almost anything and/or application. Camping, backpacking, beach outing, Grunion Run at the beach. Flip out this light to resolve almost any night time application. The one real drawback is when this light is on anything above Med setting it gets HOT!!!!, hot enough not to hold for any period of time. Having the strobe setting at 10,000 lumens can be seen for miles, reflecting off of the surrounding trees or cliff side to bring greater attention to your surroundings and increase the chances of being found. Running on 50 lumens for 80 hours could be a definite lifesaver. Attach a lanyard to this light and carry it around your neck, use as a self defense flash on strobe in the attackers face will blind anyone, long enough to get away or disable the attacker. Heavy enough to swing and launch this light against another person would do some incredible damage.
But I guess in the end, you would have to be in a more rural state or have that undeniable urge to be in the great outdoors to use this light effectively. Six LED's and an actual glass front lens with an all aluminum body makes this light indestructible against the elements.

Great unit, but with a few minor control design issues - terrible unusable (defective?) holster

This light has tremendous output, though the duration of anything beyond the medium setting, this decays substantially and noticeably within minutes - and that is expected. The build quality is excellent - except for the cheap holster that is so tight as to be unusable. Unlike the "unboxing" videos that I watched - wherein the light was placed head first (down) into the holster, this unit arrived with the light upright and fully unprotected. I found out why - once inserted with difficulty, the unit cannot be removed without using two hands and great effort - all while the sharp edge of the head cylinder scraping against the holster material's edge seam in a manner that will surely lead to it separating. I am hopeful it is simply defective and plan to contact Fenix to try to have it replaced. That has greatly marred my overall experience as the holster is a much needed piece of equipment for me in order to use this unit as intended. Lastly, I care for the user interface on the TK35UE V2.0, which I also own, much better. When I first turned on this light it was in turbo mode - highly suggestive that it had been operated by someone else before I purchased it - perhaps it was returned for some reason - and that might explain the light being upside down in the holster (the only way it will fit in my case. Accordingly, an external clue as to the light's output setting - and/or some restriction on maximum (turbo) output being a memory default -would be an improvement. I'll see how Fenix handles the holster situation before passing final judgment.

Please note we do not send out previously opened products.

Awesome Light!

This light is awesome! It fits perfectly into your hand and is the perfect weight. When you turn it on, you will never buy another one again. It fills every need, from economy to turbo. Turbo mode lights up everything, it’s blows my mind how bright it is.
Awesome job Fenix! Great quality and great customer service as they helped me replace a loose clip by sending me a new one. Fenix has a new loyal customer.
Thank you, Tony
