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
