Fenix HL40R is a headlamp type. It is equipped with an elastic strap, with which it is attached to the head or to a protective helmet. The occipital band of this strap is made double, which contributes to a more reliable fixation.
Fenix HL40R works due to the modern and quite powerful Cree XP-L HI V2 LED. It provides a brightness of 600 lumens in Turbo mode. And an additional advantage of this model is the presence of a mechanism for manual adjustment of the lighting distance and beam angle. It is a rotating ring that changes the beam width from 13° with additional radial illumination to 52° to 75° with uniform flood light. At the same time, the lighting distance varies from 4 to 147 meters in different modes. Such a lantern is equally convenient to use for reading in a tent, lighting the entire camping area, or moving along a tourist route.
