Not as good as the past

2nd one I've bought, loved the first one. Not at all happy with the resent purchase, head band is not user friendly and to small. Should of kept it simple, at least it worked.


I've used this several times for early morning runs and camping trips. It is great, it stays up even when running but doesn't squish my head.

The Perfect +1 Headlamp

The HL18R-T is the perfect +1 headlamp! Given that I also own the HM65R-T & HL32R-T, both of which are my primary, overnight, long-lasting (ultramarathon) headlamps, the HL18R-T perfectly fills the gap left by those two and serves as my early morning/late evening go-to. With a superb (rechargeable) battery, exceptional brightness in all conditions, and a lightweight, storable package, the HL18R-T gets me through my shorter, less intense (time-wise) early/late training miles without issue. I never have to worry about this headlamp not working when I need it to (unlike others I’ve used before), and regardless of condition-rain, sun, or snow-the HL18R-T gets the job done. Well worth the price of admission! The perfect compliment to the rest of the Fenix running line and, in my opinion, the best bang for your buck headlamp on the market today. Never a dull moment!
