Thyrm VariArc in the Wild


As you can see the Thyrm VariArc is beginning to appear more and more frequently “in the wild”. That’s a testament to its utility as a helmet accessory and usefulness in a wide range of tasks and applications.

The VariArc is a helmet light mount with 360 rotation. First introduced in October 2019, the light mount has become increasingly ubiquitous in several career fields. It’s seen, survived, and proven itself during law enforcement responses to civil unrest, on military operations in various places, and across the spectrum of first responder activities. 


The VariArc is intended to provide a variety of task light options. It can be indexed forward for direct illumination, down for a bounce light effect, up for an umbrella/canopy applications…whatever is needed. Keep it locked in forward, or twist and unlock to rotate it through 8 additional index points for administrative use.

Thyrm, a part of the HMW Tactical Alliance, says of the VariArc,

“The locking teeth are biased to the forward position, keeping your light aligned for the most critical uses, but with a firm twist, the VariArc mount unlocks and rotates…Its small footprint and low-profile keep things tidy and the Picatinny Rail allows for maximum compatibility with visible and IR lights..”
