The Fenix WH35RE is a safe work headlamp for explosive environments, designed for various areas with explosion risk, excluding underground mines. It is equipped with ATEX/IECex certification. It offers a maximum output of 280 lumens and is powered by a specially modified ARB-L21-3000Ex Li-ion battery with a capacity of 3000 mAh (included in the package), which is recharged directly in the flashlight via a modern USB-C connector. The practicality of the headlamp is enhanced by the ability to remove the light from the head mount and use it as a handheld or work flashlight. Additionally, the headlamp is equipped with a detachable steel clip, so you can easily attach it to a pocket or strap. Its large switch allows for simple and precise operation – even with gloves on.

The WH35RE has been certified by several explosion-proof certifications, including IECEx, ATEX, and GRGT. Therefore, this product is safe to use in explosive atmospheres classified as Zone 1 and Zone 2, as well as in combustible dust areas classified as Zone 21 and Zone 22.
