Which one to pick
Take the Fenix HM65R-T
Leads on Performance and Durability.
- Night trail running, where seeing thirty meters ahead decides your pace
- Search, night work, and anything that has to keep going past midnight
- You already own 18650 cells and a charger, so spares cost nothing new
Take the Petzl Actik Core
Leads on Value and Design.
- Trips that start on a charger and end somewhere with a shop that sells AAA
- Mixed use — camp, night walks, an occasional run on the flat
- You want a red mode that comes on without cycling through white first
What each one gets wrong
Fenix HM65R-T
- Weight on the forehead matters; this is the heavy end of the category
- You want it to run at 1,500 lumens rather than step down to hold temperature
- Simple is the goal — two buttons and separate emitters take learning
Petzl Actik Core
- The lamp will be out in sustained rain; IPX4 is splash, not weather-proof
- You need a beam that reaches, rather than one that floods close ground
- You object to a proprietary pack you will eventually have to replace
