(23 customer reviews)



The HL18R is a compact USB rechargeable headlamp with extreme versatility. It features two separate beam options (spot and flood), six different lighting levels (plus SOS), and allows you the unique ability to use multiple options to power the headlamp. The simple operating system can quickly get you into utilizing the soft neutral beam that magnifies natural colors with a simple click of the button. The headlamp can blast a max output of 400 lumens and reach runtimes of up to 150 hours. If you find yourself in a situation when you can’t recharge the included 1300mAh battery, then you can simply pop-in three of your favorite AAA batteries to operate the light.

All of this is built into a ultra-light 2.8 ounce (80 gram) body being held in place by a remarkably comfortable headband with reflective strips and anti-slip design. This headlamp is the answer for your trainings in the early morning and late evening when the day needs extended; when chasing the fire flies won’t wait; or when that tent needs to be put up before your head can lay down. Count on the versatile design of the Fenix HL18R to be there for you.

Overheat Protection

The light will accumulate a lot of heat when used on Turbo output level for extended periods. The light will automatically step down by a few lumens to reduce temperature.

Headband Assembly

Notice: The headband is factory assembled by default.

Step 1: Attach the headband to the headlamp as shown (Pic 1), by first sliding the band down to the bottom of the slots. Then hook the top edge under the top slot.

Step 2: Adjust the headband by sliding the buckle to required length.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the headlamp and will void the warranty.
  • Fenix strongly recommends using quality rechargeable Ni-MH batteries.  Alkaline batteries will shorten the runtime with the lamp switched on high output.


This light is a high-intensity lighting device capable of damage to the user or others. Avoid shining the light into anyone’s eyes.

also a trail runner review :) got this on the release date, was pretty excited at the spec particularly 400 lumens for 8.5 hrs, seemed too good to be true...and yes it is. I uploaded a picture which compared this one's 400 lumens with my UC35's 350 lumens, you can see this one is more like 100-150 lumens, I actually compared it (400 lumens) to 150 lumens of UC35, it's not as bright as 150. Beside of not bright as advertised, I was more disappointed at how really really short time at "high" lumen output, it only last a few minutes on "400" lumens, what do I use it for? (ah I do know one, UTMB required a 200 lumens light, so this will fit the bill this August when I run it. Like all of their bullshit mandatory equipments, I'm constantly looking for something just to shut them up) So beware of this new spec listing, i.e. 400 lumens 8.5hrs doesn't mean you'll have that bright level for that long, it just means the light will not die for 8.5hrs, which can be a good thing, a peace of mind. I do agree this is a comfortable and very light head lamp. But it's not a really bright one, it's more like 70 lumens whole night one. Personally I don't think 70 lumens is nearly enough bright for trail running (if you want to run), at least not for any moderate technical trails, not as a primary light source. But as a second light source or backup, this will be a perfect one due to its lightness and comfortableness and last a whole night no matter what kind of setting. As for the spot vs floor mode, I don't know what the floor mode will be used since it's so dimmed, but maybe it can be also served as a backup in case of the spot light bulb dies. I returned this one not because I don't like it, I do like it as a secondary light, but I already own a whole lot of lights so it's too luxury for me to own another one. Instead I will wait for the new HM65R which is past due of release for like a year now.

    Good light. Like the color temp. Unfortunately they sent the wrong product the first time around and it was lost during transit before being delivered late to the persons birthday whom I bought it for.

    Works fine except I don’t know how they got the battery life ratings so wrong. At max setting, it definitely doesn’t last 8.5 hrs on the included battery. Maybe 3-4 hours. Kind of annoying because I bought it specifically for the long rated battery life.

    Dim light. While “lumens” may show this is a “powerful” headlamp, the color is so yellow it’s illumination is worse than a $20 WalMart headlamp. I called Fenix for a return >week ago, still waiting for a call back. Don’t waste your $’s on this light, not as advertised. 1st Fenix light I’ve ever bought that disappointed me.

      Yes, the HL18R is a neutral light, as listed in the description. Neutral lights have a yellow color. The HL18RW is a cool white LED. Warranty is reaching out to you for that return.

    Nice, but haven’t yet tried it.
