How we calculate scores →About this gear
LED NAUTILUS MKII is Ammonite’s new adjustable-beam light head. A Fresnel lens and magnetic-clutch zoom ring vary the published beam from 4.7 to 60 degrees, with a maximum claimed output of 3,200 lumens.
Consider before buying
This is the MKII announced for the first October 2026 batch, not the older 4,000-lumen Nautilus. Earlier Nautilus reviews and retailer comparisons cannot grade the new design. It also requires an external battery system; the head is not a complete torch.
Our take
Consider MKII if changing between a narrow spot and a wider beam is more useful than a fixed beam. The 366 g head is larger and heavier than the listed Speleo MKII, so compare handling as well as light output. Current evidence is manufacturer documentation; no independent overall rating for this new generation was verified.
