Armytek Elf C2

Armytek's cheapest 18650 headlamp, and the revision that finally moved from micro-USB to a USB-C port. Output is 1,100 lumens (1,023 in the warm tint) stepping to 650 after four minutes for 2 hours 32 minutes, through a 70-by-120-degree TIR to 105 metres; the lowest mode runs 200 days. Six modes, digital stabilisation, IP68 to ten metres and a ten-year warranty, in a 65-gram body, 115 with the cell. The maker names no emitter or CRI and gives no candela, so 2,756 is derived from the maker's beam distance; independent testing measured the same figure on the previous micro-USB revision.

The price shown is a snapshot from the last catalog sweep, not a live figure. Links to a brand's own store are not paid placements and earn us nothing.
