What owners report
Sofirn HS40
- ✓Ships with both 18650 and 18350 tubes — long runtime or light on the head
- ✓Buck driver with better regulation than earlier Sofirn headlamps
- ✓USB-C port sits nearly flush under its plug
- ✓Simple interface with nothing to learn
- ✓Right-angle body works as a headlamp and as a work light
- ✗The button is on the end rather than the side, so no pinch activation
- ✗Less independently reviewed than Sofirn's headline headlamps
- ✗No high-CRI option in the standard configuration
- ✗18350 tube trades most of the runtime for the weight saving
- ✗Basic feature set with no secondary emitter
Wurkkos HD15R
- ✓Same well-rated HD15 platform: dual emitters, magnetic tailcap, strong build
- ✓USB-C charging in the head at over 2.3A
- ✓Nothing to lose — no cell to misplace or fit incorrectly
- ✓Smaller and lighter than the 21700 HD20
- ✓Good value for the feature set
- ✗Sealed cell — no swapping a fresh one in on a long night
- ✗Finite lifespan: when the battery degrades the light is finished
- ✗Too few brightness levels, as on the removable-cell HD15
- ✗Published runtime figures overstate reality by two to three times
- ✗No Anduril, so the mode spacing can't be reconfigured
