What owners report
Emisar DW4
- ✓Owners in caving, mine exploration and search and rescue call it flawless
- ✓Light enough to wear on a helmet for hours
- ✓Boost driver gives good efficiency and regulated runtime
- ✓Choice of optics and emitters, as with every Emisar
- ✓CNC-machined aluminium with trapezoid threads and factory lubrication
- ✗No USB-C charging or reverse charging — the cell comes out
- ✗Takes unprotected flat-top 21700s only
- ✗Protected and button-top cells won't fit at all
- ✗Ordering goes through a small-batch supplier with long lead times
- ✗Anduril's configuration menus are steep for a first enthusiast light
Wurkkos HD20
- ✓High-CRI neutral flood emitter alongside a dedicated spot
- ✓USB-C PD charging, and it works as a power bank for a phone
- ✓Excellent runtime and sustained performance on high from the 21700
- ✓Rugged enough to double as a standalone right-angle flashlight
- ✓Flood beam is well judged for close-range work
- ✗The largest headlamp most reviewers have handled — bulky on the head
- ✗Switching between emitters fails around half the time
- ✗The head strap is noticeably lower quality than the light
- ✗The XP-L HD spot emitter under-throws for the format at 141 m
- ✗UI niggles, including losing moonlight when you switch emitters
