Quick Specs
What I Like
What I Don't
Ground rule before anything else. This is a recon report, not a review. I have never had this headlamp on my head. Everything below is a read of the product page Longhorn Tactical publishes, and the real review comes after I have one in hand and take it through a few dark mornings.
The Spec Read
Fenix lists two emitters up front: a Luminus SST40 for white and an OSRAM GW PUSTA1.PM for warm white. The claimed numbers are 1600 lumens max, 7353 candela, and 185 yards of peak beam distance.
The published runtime table is short and specific: 1600 lumens for 3 hours on High, 400 for 12 hours on Med, 130 for 24 hours on Low. That 3 hour figure is an ANSI runtime, so it includes thermal step down from peak. Nothing on the page says how long it actually holds 1600.
The housing is listed as magnesium alloy, which Fenix calls 30 percent lighter than aluminum. Listed weight is 4.94 oz with battery and headband, in a head measured at 3.15 by 1.84 by 1.37 inches. The page rates it IP68 with 2 m impact resistance. Power is a single 3400mAh ARB-L18-3400 cell, listed as included, charged over USB-C, though no charge time is stated anywhere. The box list also includes a spare O-ring, a USB-C cable, and the manual.
Two numbers do not hold up. The copy advertises seven brightness levels while the spec table lists three, and the other four are never named. The over 600 hours max runtime is not tied to any lumen level on the page. Both stay marketing numbers until Fenix publishes the rest.
Who It Is For
The product name says trail running. I read it the other way around. This is an 18650 riding in the housing on your forehead at a listed 4.94 oz, and dedicated running lamps move the battery to the back of the strap for a reason. The page does not address bounce or forehead pressure over distance. I have not run in it, so I am not going to tell you it is fine and I am not going to tell you it is not.
Weight matters less when you are standing still, and that is the list this spec sheet actually fits: under the hood in the driveway, the crawlspace, pitching a tent at 9pm because bedtime got away from you, hauling firewood. 1600 claimed lumens is a lot of light for that work, and the warm white is the emitter I would expect to reach for close up.
A headlamp does not replace a pocket light, it is the other half of the kit. I carry an Olight Baton 4; one frees your hands, one lives in your pocket. The best EDC for dads guide covers how the two fit together.
One gap worth naming: no red mode is listed here. The Fenix HM50R V2.0 that Longhorn also stocks does list one. If tent use and night vision matter to you, do not assume this has it.
The Honest Math
$104.95 with no compare-at price, three colorways at the same money: Black, Purple, and one called Nebular that the page never explains. Check Fenix direct before you call that a deal.
Two more things to settle before you click. The page never states a warranty length, so I am not publishing one, and Fenix handles warranty claims rather than Longhorn, so the receipt does not give you a retailer to go back to. Availability is unclear too: the page shows a backorder notice while the product data reports in stock in all three colors. Confirm what you are actually buying before you order.

After Action Report
On paper this is a lot of headlamp for $104.95: two emitters, 1600 listed lumens, a magnesium body, IP68, and a 3400mAh cell in the box. The spec sheet earns a look for camp, truck, and garage work, less so for the running job the name advertises, and the missing red mode is a real gap to know about first. No verdict until I have one in hand.
